In physics, you will learn about several motions of the body. Do you ever think about what causes motion in these objects? Well, it is force. Similarly, what stops the object under motion? That is also a force. So, you see that force and motion are basically two sides of a coin. For instance, we see the interdependence of force and motion in throwing a ball and catching a ball. This article will take us through the meaning of force and motion and the relation between them.
Force is basically a push or pull which acts on an object or energy as an attribute of physical action or movement. It happens when two entities are in contact. Further, motion is when a body is moving, it is in motion. Thus, we will now look at these separate topics in detail.
For instance, suppose there are two bodies of mass M and m. They are positioned in such a manner that the body with mass m is resting over the body with mass M. In physics, we will state that these two bodies will exert forces on each other. Thus, we can say that whenever there is an interaction between two or more bodies, force is going to be a part of the interaction.
Whenever a body is moving, we state that it is in motion. For instance, if a girl is walking down the street from a park to her home, we will say that the girl is in motion. However, suppose that girl stops for 2 minutes on the way to buy candy.
Force and motion deeply connect in nature. In other words, force is the cause of motion. If something is moving, we will say that some force is acting on it or some force must have acted on it which is producing this motion.
If a woman is walking, and hence in motion, there must be some force acting on her which is making her move. So you ask, what is this force? It is the muscular force of her body. In simpler terms, force is neither a push nor a pull.
Naturally, we can describe motion as a change in speed, or change in direction. The first person to discover the relation between both was Sir Isaac Newton. He concluded that force can accelerate the body, decelerate the body and it can change the direction of the moving body.
A 2-dimensional motion and force study of the ankle joint during gait has been carried out on normal subjects and patients with ankle joint disease, before and 1 year following total ankle replacemetn. The methods employed involved the use of high-speed motion picture film, force plate and foot-switch data. The Achilles and anterior tibial tendon forces, the compressive and tangential (shear) forces across the ankle during stance phase of gait were determined, based on a quasi-static analysis. During stance phase of gait normal subjects used a mean of 24.4 degree of sagittal plane ankle motion. Patients with ankle joint disease showed reduced motion which returned to near normal values 1 year following total ankle replacement. Compressive force across the ankle joint rose to about 5 times body weight during the latter part of stance phase. Backward, or aft, shear forces or nearly full body weight were demonstrated during all but the last 20% of stance phase. Patients with ankle joint disease apparently altered their gait to markedly reduce these forces. Following total ankle replacement, shear forces returned toward more normal values, but compressive forces were not significantly changed.
His second law defines a force to be equal to change in momentum (mass times velocity) per change in time. Momentum is defined to be the mass m of an object times its velocity V.
Remember that this relation is only good for objects that have a constant mass. This equation tells us that an object subjected to an external force will accelerate and that the amount of the acceleration is proportional to the size of the force. The amount of acceleration is also inversely proportional to the mass of the object; for equal forces, a heavier object will experience less acceleration than a lighter object. Considering the momentum equation, a force causes a change in velocity; and likewise, a change in velocity generates a force. The equation works both ways.
The velocity, force, acceleration, and momentum have both a magnitude and a direction associated with them. Scientists and mathematicians call this a vector quantity. The equations shown here are actually vector equations and can be applied in each of the component directions. We have only looked at one direction, and, in general, an object moves in all three directions (up-down, left-right, forward-back).
His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.
In physics, we come across various motions of a body. What causes the motion of an object? The answer is a force. What stops an object under motion? The answer is Force. Thus, in general Force and Motion are like two sides of a coin. Example: the interdependence of force and motion is seen in throwing a ball and catching a ball. Let us first understand the meaning of force and motion individually and then the relation between them.
We can say that force is a push or pull acting on an object or energy as an attribute of physical action or movement. This occurs when two entities are in contact. According to the universal law of gravitation, every object in this universe exerts a force on others. The force acting on an object is given by the following parameter:
For example, if there are two bodies of mass M and m, and they are kept in such a way that the body with mass m is resting over the body with mass M. In physics we say that these two bodies will exert forces on each other. So we can say that whenever there is an interaction of two or more bodies, force is a part of the interaction.
Force and motion are deeply related in nature. We can say that force is the cause of motion. Suppose something is moving, we can say that some force must be acting on it or some force must have acted on it which produced this motion. If a person is walking, and hence in motion, there must be some force acting on it which is making him move. What is this force? This force is the muscular force of his body.
But what exactly is does state of motion mean? In physics, motion is defined as the change in position with respect to time. In simpler words, motion refers to the movement of a body. Typically, motion can either be described as
When force is applied to a body in rest, it starts to move, provided that there is no greater force opposing it. When you throw the ball towards the batsman while playing cricket, the ball starts to move forward from its initial position of rest in your hands.
On the other side of the spectrum, if force is applied on the opposite direction of a moving object, it will decelerate or slow down and eventually stop altogether if the force is continued to be applied. For example, when a goalkeeper stops a ball, he causes it to decelerate and stop.
When force is applied on an object in an angle different to its direction of motion, it causes the object to change motion. Almost every ball game uses this principle. The speed can be maintained if the force is applied in a perpendicular angle but the velocity will change.
Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows:
The three laws of motion were first stated by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), originally published in 1687.[2] Newton used them to investigate and explain the motion of many physical objects and systems, which laid the foundation for classical mechanics. In the time since Newton, the conceptual content of classical physics has been reformulated in alternative ways, involving different mathematical approaches that have yielded insights which were obscured in the original, Newtonian formulation. Limitations to Newton's laws have also been discovered; new theories are necessary when objects move at very high speeds (special relativity), are very massive (general relativity), or are very small (quantum mechanics).
Newton's laws are often stated in terms of point or particle masses, that is, bodies whose volume is negligible. This is a reasonable approximation for real bodies when the motion of internal parts can be neglected, and when the separation between bodies is much larger than the size of each. For instance, the Earth and the Sun can both be approximated as pointlike when considering the orbit of the former around the latter, but the Earth is not pointlike when considering activities on its surface.[note 1]
The physics concept of force makes quantitative the everyday idea of a push or a pull.[note 3] Forces in Newtonian mechanics are often due to strings and ropes, friction, muscle effort, gravity, and so forth. Like displacement, velocity, and acceleration, force is a vector quantity.
Newton's first law expresses the principle of inertia: the natural behavior of a body is to move in a straight line at constant speed. In the absence of outside influences, a body's motion preserves the status quo.
The modern understanding of Newton's first law is that no inertial observer is privileged over any other. The concept of an inertial observer makes quantitative the everyday idea of feeling no effects of motion. For example, a person standing on the ground watching a train go past is an inertial observer. If the observer on the ground sees the train moving smoothly in a straight line at a constant speed, then a passenger sitting on the train will also be an inertial observer: the train passenger feels no motion. The principle expressed by Newton's first law is that there is no way to say which inertial observer is "really" moving and which is "really" standing still. One observer's state of rest is another observer's state of uniform motion in a straight line, and no experiment can deem either point of view to be correct or incorrect. There is no absolute standard of rest.[note 4]
