Newton's laws

Newton’s first law

an object in equilibrium will remain in its current state of motion

what does newton’s first law describes

an object in equilibrium

what is newton’s first law also called

law of inertia

what is wrong with this definition of newton’s first law : an object in motion will remain in motion and an object at rest will remain at rest unless acted upon by an outside force

“in motion” and “outside force”

Newton’s second law

an object’s acceleration is directly proportional to the net force acting on the object and inversely proportional to the objects mass

What does newton’s second law describe

Describes objects that are not in equilibrium

What is newton’s second law also called

law of acceleration

Newton’s third law

when two objects interact, the force object one applies to object two has the same magnitude but opposite direction as the force object two applies to object one

What does newton’s third law states exists

forces exists in pairs

what is newton’s third law also called

law of interaction

force diagram

a picture of an object at one moment in time that includes all the forces acting on the object at that moment
