- State displacement as the change in position and distinguish its signed/vector meaning from distance travelled.
- Calculate net displacement from the signed area under a velocity–time graph, including intervals where direction changes.
- Interpret the sign of a position or displacement using the stated reference direction.
- Determine the separation or relative displacement between objects from their velocity–time graphs.
- Combine perpendicular or sequential components to calculate the magnitude of a two-dimensional displacement, including projectile motion and circular-track geometry.

IB Physics SL A 1 3 Displacement Questions question 1
This question is in two parts. Part 1 is about kinematics and gravitation. Part 2 is about radioactivity.
Part 1 Kinematics and gravitation
A ball is released near the surface of the Moon at time t=0. The point of release is on a straight line between the centre of Earth and the centre of the Moon. The graph below shows the variation with time t of the displacement s of the ball from the point of release.
State the significance of the negative values of s.
