distance time graphs

• Horizontal line= object is not moving
• a constant straight line, pointing diagonally on this graph means the speed is constant
• steeper diagonal line= object moving away with constant speed but faster.
• flatter diagonal line = object moving away at slower speed
• distance-time graph can be used to find acceleration
• the gradient of a distance-time graph gives us the average speed over that period of time
• Diagonal line downwards= object moving back towards start with constant speed.
