Student Projects/Force and Motion
FORCE AND MOTION
In this lesson we will be learning about forces and it effects.
It can be defined as push (or) pull.
In our everyday life we observe that some effort is required to put a stationary object in motion or stop a moving object. We ordinarily experience this as a muscular effort and say that we must push or pull or hit on an object to change its state of motion.
Force can be used to change: (i) the magnitude of velocity of an object, (ii) its direction, (iii)the shape of size of objects.
BALANCED FORCE:Forces that are equal in magnitude and opposite in direction. They don't cause motion.
UNBALANCED FORCE:Forces that are not equal in magnitude and opposite in direction. They cause motion.
It can be defined as the change in position of object over time.
"FORCE is the cause of motion"-it is the force which is responsible for the movement of an object.
