Force and Motion
Before we dwell into how force can affect the state of motion of a body, let’s take a glance at the force. Force is an interaction between two or more bodies that when unopposed causes a change in the state of motion of the objects. So in the definition of force itself, it explicitly states that force is something that causes a change in the state of motion. Force can also be thought of as a push or a pull. So let’s see how force affects the state of motion of a body. But what exactly is a change in the state of motion? A change in the state of motion corresponds to either a change in the speed of the body and/ or a change in the direction of motion of the body. The change in speed could mean speeding up (acceleration) or speeding down (deceleration).
A ball cannot move on its own, neither can a chair or a table. All non-living objects are stationary unless a force is acting on them. You need to have an engine to generate force in order to make it move, you need to kick the ball which is a form of applied force in order for the ball to fly into the goal. The chair will not move unless you move it. All these are examples of how force plays a huge role in our daily life.
