describe an activity to show that force can chage the state of motion
Answers
Answer:
A hockey player changes the direction of the moving ball with a flick of the stick (Fig. ... In all these situations the ball is either made to move faster or slower or its direction of motion is changed
Explanation:
ex.1A 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.
ex.2When you kick a stationary ball. You are applying force to it through your legs which causes the ball to start moving. This is not the only effect though, the force can also cause an increase in motion if it is applied in the same direction in which the body is moving. For example, if you’re cycling and you’re already in motion, by pedaling some more you are effectively using force to increase the speed in which you are traveling. This is an example of force being used to speed up or cause acceleration. We should remember that the acceleration happens only as long as a force is being applied. If the force is removed, the acceleration stops.
