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 how fast something moves.

Velocity is how fast it moves and in what direction it moves in.

Acceleration is the change in how fast it moves. I.e. if it speed up or slows down.

Here we are not given a speed, but we are told that Usain Bolt can increase it (change it) faster than any other runner which means we have been given a change in speed (acceleration, speeding up), therefore it is acceleration.

Hope this helped!
