Quick questions on Motion graphs and free fall: N(A)-Level Physics kinematics
3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What are distance-time graphs?Show answer
On a distance-time graph, the distance is on the vertical axis and time on the horizontal axis.
What are speed-time graphs?Show answer
On a speed-time graph, speed is on the vertical axis and time on the horizontal axis. These graphs carry two pieces of information.
What is free fall?Show answer
Free fall is motion under gravity alone, with no air resistance. Near the Earth all objects fall with the same acceleration, the acceleration of free fall:
