Impulse with Variable Forces Video Lessons

Concept

# Problem: The force vs. time graphs for two collisions are shown. Which collision has the largest impulse? A. The impulses are the same. B. The impulse for collision 2 since it lasts longer. C. The impulse for collision 1 since it has the larger maximum force. D. Cannot be determined since the initial an final speeds are unknown. E. Cannot be determined since the masses are unknown.

For varying forces, the total impulse is the area under the Force-Time graph.

$\overline{){\mathbf{J}}{\mathbf{=}}{\mathbf{Area}}{\mathbf{\left[}}{\mathbf{F}}{\mathbf{\left(}}{\mathbf{t}}{\mathbf{\right)}}{\mathbf{\right]}}}$
