What do horizontal lines on a distance time graph represent?
The steeper the gradient on a distance time graph the _________ the speed.
What is acceleration?
Change in velocity.
What are the units for acceleration?

How do you find the distance on a velocity time graph?
The area underneath.
What is a force?
A vector quantity that can make objects change speed, shape or direction.
True or False:
If the resultant for is zero it means the object is stationary.
False, it also means that the object is moving at a constant velocity.
What is force measured in?
