When an object changes velocity, it accelerates. Acceleration is the change in velocity per second and is measured in m/s 2. Acceleration is a vector quantity because it has size and direction. The ...

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 ...

The normal component of acceleration is known as the “centripetal” component. It is proportional to the square of the speed, and inversely proportional to the radius of curvature of the path. The ...

This module expands on the capabilities for teaching using a Pendulum. A pendulum by itself can provide valuable insight into harmonic motion and the relationship between frequency and period. It can ...
