Learn the difference between distance, displacement, speed and velocity, and how to calculate distance, speed and acceleration.

Just about every introductory physics lab should have some type of graph.

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled.

Why do you always make a graph in physics lab? It's not just for fun, there is a reason. Here is an example.

Shini Somara introduces us to the ideas of motion in a straight line. In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a ...
