When an energy conversion occurs due to friction, does only one of the objects increase in thermal energy or do both objects increase in thermal energy?

• Only one object increases in thermal energy

• Both objects increase in thermal energy

• Neither object increases in thermal energy

• The energy conversion does not involve thermal energy

What does the No Transfer-No Change idea state?

• Without energy transfer, an object's kinetic energy remains constant

• Without energy transfer, an object's kinetic energy decreases

• Without energy transfer, an object's kinetic energy increases

• Without energy transfer, an object's kinetic energy becomes zero

Describe the velocity-time graphs: one for a cart that slows down quickly and another for a cart that slows down slowly.

• The graph for the cart that slows down quickly will have a steeper slope than the graph for the cart that slows down slowly

• The graph for the cart that slows down quickly will have a shallower slope than the graph for the cart that slows down slowly

• The graphs will have the same slope but different intercepts

• The graphs will have the same slope and intercept

Define the term 'negligible'.

• A term used to describe a significant effect

• A term used to describe a measurable effect

• A term used to describe an effect that can be ignored

• A term used to describe an effect that cannot be measured

Provide two different examples when friction can be considered negligible.

• A car moving on a rough road

• A ball rolling on a grass field

• A book sliding on a wooden table

• A person walking on a carpeted floor

Why does rug burn occur if you slide across a carpet floor?

• Friction between the carpet and your skin converts kinetic energy to thermal energy

• Friction between the carpet and your skin converts kinetic energy to potential energy

• Friction between the carpet and your skin converts thermal energy to kinetic energy

• Friction between the carpet and your skin converts potential energy to kinetic energy
