Force and Laws of Motion- Notes

Force 

Force is an agent that tries, successfully or unsuccessfully, to move a body at rest or to stop a moving body.

A force can change the state of a body at rest, the state of motion of a body under motion, the direction of motion of a moving body or the shape of an object.

The characteristics of force are magnitude, line of action, nature and point of application.

Force is measured in newton in the SI system and in dyne in the CGS system.

Force is a vector quantity.
