force

Force-A push or pull on an object is called force.

Interaction of one object with another object result in a force between the two objects.

Magnitude and direction of force

Forces applied on an object in the same direction added to one another.

For opposite direction

Net force decides the effect on the object The net force acting on the object is the differences between the forces.

If the direction or the magnitude of the applied force changes,it’s effect also changes

Change in direction/magnitude=change in effect

Net force is zero if forces are equal from opposite directions

A forces can change the state of motion

If object is in the rest/not moving it is in state of rest and if it is moving it is in state of motion .Both rest and motion are the state of motion

Some important points of Forces

A force applied on an object may change its speed.

If force applied in the direction of motion=Its speed increased

If force applied in the direction opposite to the the direction of motion –it’s speed decreased

A change in either the speed of an object or its direction of motiobn or both is described as a change in the state of motion of an object.
