Kinematics

Position, velocity, acceleration. The mathematical language for describing how things move through space and time.

Free Fall Physics: Formula & Real Examples

Free fall is motion under gravity alone. Learn the h = 0.5gt² and v = gt formulas, why every object falls at the same rate, and how to solve free-fall problems step by step.

Velocity vs Speed: What’s the Difference?

Speed is a scalar and velocity is a vector — that one difference is why average velocity can be zero on a round trip while you still cover real distance. Here's the full breakdown with examples, worked problems and an interactive demo.
