What are reading motion graphs?Show answer
The graphs encode the relationships geometrically:
What is vertical motion under gravity?Show answer
Free fall is uniformly accelerated motion with (about ) directed downward. Choose a sign convention (commonly upward positive) and apply it consistently: the launch speed, the acceleration and the displacement all carry signs relative to that choice.
What is q1?Show answer
Define velocity and acceleration, and state how each is found from a velocity-time graph. [3 marks]
What is q2?Show answer
A cyclist accelerates from to in . Find the acceleration and the distance travelled. [3 marks]
What is q3?Show answer
An object is projected vertically upward and returns to its starting point. Sketch its velocity-time graph and explain what the area between the line and the time axis represents. [3 marks]
