š¬ A picture of motion
Words and numbers describe motion — but a graph shows it at a glance. How can a line on graph paper tell us position, velocity and even acceleration?
Why use graphs to describe motion?
- A graph gives a visual picture of how position, velocity or acceleration change with time.
- Graphs help us compare the motion of two objects, calculate physical quantities, and tell uniform from non-uniform motion.
- We plot one quantity (position/velocity/acceleration) against another (time).
