Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

Suppose you throw some object near the surface of the earth. If the only significant force on the object is the constant downward gravitational force, we call this "projectile motion." Yes, that ...

Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken. is the rate of change of velocity. It ...
