Everything CCEA students need to know about velocity and acceleration for GCSE Physics. ... distance moved = 10 m + 10 m + 10 m + 10 m = 40 m. Speed = 40 m ÷ 20 s = 2 m/s.

(Whereas velocity is measured in m/s, acceleration is measured in meters per second squared, or m/s 2.) How does this constant acceleration affect the distance that an object travels over time?

Acceleration (a)- the rate of change of an object’s velocity over time. Displacement (s)- the total distance and the direction the object travels. Final Velocity (v)- the object’s velocity at ...

The iPhone makes it easy to do all kinds of cool physics. Like, say, use the change in velocity in an elevator to measure the height of a building.

I had an interesting thought, spurred on by a discussion I ran across online about firing guns in space. Apparently, smokeless powder contains its own ...
