What are the differences between elastic and inelastic collisions?
Elastic: Kinetic energy conserved, objects bounce. | Inelastic: Kinetic energy not conserved, energy lost as heat/sound, objects may stick.
What are the key differences between elastic and inelastic collisions?
Elastic: Kinetic energy is conserved, objects bounce off each other. Inelastic: Kinetic energy is not conserved, energy is lost as heat/sound/deformation, objects may stick together.
What is the effect of increasing the time interval over which a force acts?
For the same impulse, increasing the time interval will decrease the force required, and vice versa ().
What happens when multiple forces act on a system?
The net force (vector sum of all forces) determines the change in momentum of the system.
What is the effect of a perfectly inelastic collision?
Objects stick together after the collision, and kinetic energy is not conserved.
What is the effect of a closed system?
In a closed system, the total momentum remains constant.
