Acceleration-time graphs: $area = change in velocity$
Motion Along a Straight Line — AQA A-Level Physics
- A horizontal $line = constant accelerationThe rate of change of velocityThe rate of change of displacement. A vector quantity. Measured in m s⁻¹.. A vector quantity. Measured in m s⁻².$.
- A line at $a = 0 = constant velocityThe rate of change of displacement. A vector quantity. Measured in m s⁻¹. (no accelerationThe rate of change of velocityThe rate of change of displacement. A vector quantity. Measured in m s⁻¹.. A vector quantity. Measured in m s⁻².)$.
- The area under an accelerationThe rate of change of velocity. A vector quantity. Measured in m s⁻².-time graph equals the change in velocity.
- The gradient of an acceleration-time graph has no standard physical meaning at A-Level.
