BRAINCAKEForce-Time Graphs for Impacts
For impact forces if a graph of force against time is plotted, the area under the graph is the change in momentum or impulse.

Key terms in this lesson
- Impulse
- The product of the force acting on an object and the time for which it acts; it equals the change in momentum that the force produces.
- Momentum
- The product of an object's mass and its velocity; a vector quantity, conserved in any interaction provided no external resultant force acts.
