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 ...

Introduction Have you ever played a video game with a controller that used motion controls? Do you ever wonder how sometimes a smartphone seems to "know" if you're moving? How do these electronic ...

This isn’t really breaking news, but there was this story of a guy that dropped his iPhone 4 out of a plane. The man was quite happy to find his iPhone unharmed. It was partially protected by Griffin ...

When an object does not start at rest, you need to measure both the initial velocity and the final velocity to be able to calculate the acceleration. One way to to do this is to use a double mask. A ...

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 ...

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 ...

Weirdly, spaceships have no direct way to gauge their own speed. Luckily, we can use some physics tricks to figure it out.
