What is the velocity of an object?
Its speed in a given direction
1 of 6
What happens if the velocity of a body changes?
We say that it accelerates
2 of 6
Why is velocity a vector?
Because it has direction as well as magnitude
3 of 6
Why is speed scalar?
Because it is non-directional
4 of 6
What does the gradient of the line on a velocity-time graph represent?
Acceleration
5 of 6
What does it mean if the line on a velocity-time graph is horizontal?
The acceleration is zero, therefore the object is travelling at a steady speed
