Newton's laws of motion

Definition

Newton's laws of motion are three fundamental principles that describe the relationship between the motion of an object and the forces acting upon it. They explain how objects move when acted upon by external forces.

Related terms

Force:

A force is a push or pull on an object that can cause it to accelerate or change its state of motion.

Inertia:

Inertia is the tendency of an object to resist changes in its state of motion. It is related to an object's mass.

Momentum:

Momentum is the product of an object's mass and velocity. It describes how difficult it is to stop or change the direction of an object's motion.
