1.2 Plot and interpret distance-time graphs

Plotting

• Distance must be on the y axis
• Time must be on the x axis

Interpreting

• Straight horizontal line (--) means the object is stationary
• Diagonal line upwards ( / ) means the object is moving forwards. The steeper the line, the faster it is moving.
• Diagonal line downwards ( \ ) means the object is moving backwards. Again, the steeper the line, the faster it is moving.
• Although this will most likely not appear in GCSE questions, a curve upwards also means there is an acceleration, a downwards curve means a deceleration
