change the speed of an object
change the direction of the object
stop a moving object
make a stationary object move
change the shape & size of the object
change the speed of an object
change the direction of the object

FORCE______
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...__:-)
USES OF FORCE:_-
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: Consider the image beside; as the player kicks the ball the changes its speed from zero to a non-zero value thus changing the state of motion of the ball. Similar situation can be thought when a player kicks a moving ball in the game(increasing the speed of moving object)
Example of decrease in speed:
The image in the side shows that as the dog catches the ball its speed comes down from a non-zero value to a zero value, which finally results in change of state of motion of the ball
It is clear from the image besides that as the person hits the ball from the bat the direction of motion of ball changes thus changing the direction of motion of the ball....___:-)
