Velocity, Acceleration, Distance-Time Graphs, Velocity-Time Graphs

Velocity has both speed and direction. It is a vector.

Speed and velocity are both measured in m/s - they both imply how fast you are going.

Velocity must also specify direction.

Speed = Distance / Time

In a distance-time graph:

• gradient = speed
• flat sections of the graph are where the object is stationary
• straight sections means travelling at a steady speed
• …
