How can force change the shape and state of motion of an object??
How can force change the shape and state of motion of an object??
Dear student
A force has both magnitude and direction. Strength of a force is expressed by its magnitude. But to completely determine a force we need to specify both direction and magnitude as if the direction or magnitude of the applied force changes its effect changes.
Change in State of motion State of motion of is described by direction of motion and speed of the object. Even if the speed of object is zero it is to be considered in state of motion which is referred to as state of rest. State of motion of an object cannot change until and unless some force acts on the object.
Example of increase in speed:
When a footballer hits a ball its speed increases from zero to non zero value.
Decrease in speed: when a dog catches a ball its speed decreases from non zero value to zero
Change in direction: When a batsman hits a ball its direstion changes:
CHANGE OF SHAPE
When force is applied to a spring, its shape changes, it shrinks.
When a rubber band is elongated by applying force it streches.
Hope you are clear with the explanation:)
