What are the differences between elastic and inelastic collisions?
Elastic: Kinetic energy is conserved. | Inelastic: Kinetic energy is not conserved, transformed into other forms.
Compare energy transformation in elastic vs. inelastic collisions.
Elastic: No energy converted to other forms. Kinetic energy is conserved. | Inelastic: Kinetic energy is transformed into heat, sound, or potential energy.
Differentiate between total energy and kinetic energy conservation in collisions.
Total Energy: Always conserved in both elastic and inelastic collisions. | Kinetic Energy: Conserved only in elastic collisions, not in inelastic collisions.
Compare the final velocities of objects in elastic and perfectly inelastic collisions.
Elastic: Objects typically have different final velocities. | Perfectly Inelastic: Objects have the same final velocity, moving together as one unit.
What is the difference between inelastic collision and perfectly inelastic collision?
Inelastic collision: Objects may or may not stick together. KE is not conserved. | Perfectly Inelastic collision: Objects stick together. KE is not conserved.
What are the key differences between elastic and inelastic collisions?
Elastic: Kinetic energy conserved, no energy transformation to heat/sound. | Inelastic: Kinetic energy not conserved, energy transformed to heat/sound/deformation.
Compare energy conservation in elastic vs. inelastic collisions.
Elastic: Total kinetic energy remains constant. | Inelastic: Total kinetic energy decreases.
Compare and contrast inelastic and perfectly inelastic collisions.
Inelastic: Objects may or may not stick together, KE not conserved. | Perfectly Inelastic: Objects stick together, KE not conserved, maximum KE loss.
Elastic vs. Inelastic: What happens to the objects after the collision?
Elastic: Objects bounce off each other. | Inelastic: Objects may bounce off each other or stick together (perfectly inelastic).
Elastic vs. Inelastic: Give examples.
Elastic: Billiard balls colliding. | Inelastic: Ball of clay hitting the floor.
What is an elastic collision?
A collision where the total kinetic energy of the system is conserved.
What is an inelastic collision?
A collision where the total kinetic energy of the system is not conserved; some kinetic energy is transformed into other forms of energy.
What is a perfectly inelastic collision?
A special case of inelastic collisions where the colliding objects stick together and move as one unit after the collision, resulting in maximum kinetic energy loss.
Define kinetic energy.
Energy that a body possesses by virtue of being in motion.
What does conservation of momentum mean?
In a closed system, the total momentum remains constant if no external forces act on the system.
