Net force
The overall force acting on an object when all of the forces acting on it are combined
Newton’s first law
A scientific law stating that objects at rest remain at rest
Inertia
The resistance of an object to a change in the speed or the direction of its motion
Newton’s second law
A scientific law stating that the acceleration of an object increases with increased force and decreases with increased mass
Centripetal force
Any force that keeps an object moving in a circle
Newton’s third law
A scientific law stating that every time one object exerts a force on another object
