What is the effect of applying a force over a period of time to an object?
It causes a change in the object's momentum (impulse).
What is the effect of a collision in a closed system?
The total momentum of the system before and after the collision remains constant.
What is the effect of external forces on a system's momentum?
External forces cause a change in the system's total momentum.
What does the area under a Force vs. Time graph represent?
The area under the curve represents the impulse (change in momentum).
What are the differences between elastic and inelastic collisions?
Elastic Collisions: Kinetic energy is conserved, objects bounce off. | Inelastic Collisions: Kinetic energy is not conserved, energy lost as heat/sound, objects may stick.
What are the differences between open and closed systems in the context of momentum?
Closed System: No exchange of matter/energy, momentum conserved. | Open System: Exchange of matter/energy, momentum may not be conserved.
