Question

Speed, Velocity or Acceleration?

Olympic runner, Usain Bolt
is able to increase his
speed faster than any
runner in his heat.

Answer 1

Acceleration

Step-by-step explanation:

Speed is just how fast an object is moving (i.e. 3mph). Velocity is speed in a direction (i.e. 3mph west).

Acceleration is how fast or slow speed is changing, which is what Usain Bolt is doing (increasing his speed).
