Velocity

Speed with direction v=d/t

Speed

How fast or slow s=d/t

Acceleration

Change in speed/velocity over time a=v/t a=f/m

Deceleration

Friction

When something tends to rub or does rub against something else

What direction does friction always go in?

The opposite way of motion

What is inertia and is it a force?

An object's resistance to changing its state of motion. Inertia is not a force.

Directly Proportional

When two quantities both change by the same factor

Indirectly proportional

When two quantities don't change by the same factor

Newton's Second Law

The acceleration produced by a net force on an object is erectly proportional to the net force, is in the same direction as the net force, and is inversely proportional to the to the mass of the object

Newton's Third Law

Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first
