Newton's laws of motion

Physics
Grade 9

Force is responsible for the motion of an object. The kind of force decides the kind of motion of an object. All kinds of motions follow Newton's 3 laws of motion. These laws can be used to justify various motion patterns and predict the future motion of moving bodies. A few terms associated with these laws are momentum, inertia and action-reaction forces. Using these concepts the force on a moving object can be calculated and expressed in appropriate units. This unit deals with all of the above mentioned concepts.
