Exam points
- interpret or sketch position–time and height–time graphs, using gradient and curvature to describe displacement, velocity and acceleration
- interpret velocity–time graphs by using gradient for acceleration, area for displacement and turning points for changes in direction or speed
- determine the instantaneous velocity direction from the tangent to a trajectory and identify position or velocity values from a motion figure
- calculate or interpret average speed or acceleration from stated distance, time or graph data

IB Physics SL A 1 1 Position Velocity and Acceleration Questions question 1
A ball of mass 0.250 kg is released from rest at time t=0, from a height H above a horizontal floor.
The graph shows the variation with time t of the velocity v of the ball. Air resistance is negligible. Take . The ball reaches the floor after 1.0 s .
Question (a)
(a)
Label the time and velocity graph, using the letter M , the point where the ball reaches the maximum rebound height.
[ 1 ]
Question (b)
(b)
State the acceleration of the ball at the maximum rebound height.
[ 1 ]
Question (c)
(c)
Draw, on the axes, a graph to show the variation with time of the height of the ball from the instant it rebounds from the floor until the instant it reaches the maximum rebound height. No numbers are required on the axes.
