Question 4

Speed

Answer 4

The rate of which something/someone moves or operates
Measured in metres per second (m/s)
Speed is a scalar

Question 5

Distance

Answer 5

The length of which a space is or someone or something has traveled
Distance is measured by metres (m)
Distance is a scalar

Question 6

Displacement

Answer 6

Is the length of the shortest path to or between objects (the way the crow flies)
Displacement is measured using trianglex
Displacement is a vector

Question 7

Velocity

Answer 7

The measure of the change in displacement over time
Velocity is found by by dividing displacement over time and is referred to as ‘v’
Velocity is a vector

Question 8

Acceleration

Answer 8

A vehicles capacity to gain speed
It is found by the change in velocity over time and is referred to as ‘a’
Acceleration is a vector
