CP Ch04.6 Collisions

Why are perfectly elastic collisions rare in everyday scenarios?

• Due to heat generation

• Due to friction

• Due to external forces

• Due to gravitational pull

How can the velocity of coupled objects after an inelastic collision be predicted?

• Using the conservation of energy

• Using the conservation of momentum

• By analyzing the temperature change

• By measuring the time of collision

What type of collisions are common at a microscopic level, such as gas molecules bouncing off each other?

• Perfectly inelastic collisions

• Partially elastic collisions

• Perfectly elastic collisions

• Completely inelastic collisions

What is conserved in inelastic collisions even with deformation and heat generation?

• Energy

• Momentum

• Velocity

• Mass

What is transferred in elastic collisions without deformation or heat generation?

• Energy

• Momentum

• Mass

• Velocity

Why is momentum conserved in collisions?

• Due to external forces

• Due to internal forces

• Due to friction

• Due to gravity

How does friction impact momentum conservation in collisions?

• Increases momentum conservation

• Decreases momentum conservation

• Has no effect on momentum conservation

• Reverses momentum conservation
