What is speed?

This is the distance an object travels in a given time
State the SI unit for speed

Metres per second (m/s)
What is the equation for speed?

Speed = Distance ÷ Time
What is velocity?

This is the speed of an object and the direction it is travelling in eg. 100 km/h south
What is the equation for velocity?

Velocity = Displacement (metres) ÷ Time Taken (second)
What is acceleration?

This is when there is a change in speed over a given period of time
State the SI unit for acceleration

m/s²
What is the equation for acceleration?

Acceleration = Change in speed ÷ Time taken
What are scalar quantities?

These have a magnitude (size) and do not take place in any direction eg. distance, speed and time
What are vector quantities?

These have both magnitude and direction eg. velocity
