Which of the following best describes friction?

A force that slows motion between two touching surfaces

A force that pulls objects upward

Which scenario best demonstrates potential energy being transformed into kinetic energy?

A ball dropped from a height and falling to the ground

A cold drink warming up in the sun

Which of the following is an example of heat transfer by convection?

Boiling water circulating in a pot

Which of the following best explains why a ball at a higher position has more potential energy?

It is farther from the ground, so gravity can do more work

A student places a metal spoon and a wooden spoon in a pot of hot soup. After a few minutes, the metal spoon feels hotter than the wooden spoon. Explain why this happens using your knowledge of heat transfer.

Metal is a better conductor of heat than wood, so heat moves more quickly through the metal spoon.

Wood is a better conductor of heat than metal, so heat moves more quickly through the wooden spoon.

Both spoons conduct heat equally.

The soup cools down the metal spoon.

A ball is held at the top of a ramp and then released. Describe the energy transformations that occur as the ball rolls down the ramp.

Potential energy changes to kinetic energy

Kinetic energy changes to potential energy

Thermal energy changes to kinetic energy

No energy transformation occurs

A student places an ice cube in a cup of warm water. Predict what will happen to the temperature of the water and explain why.

The water will get colder because heat moves from the water to the ice cube, causing the ice to melt.

The water will get warmer because heat moves from the ice cube to the water.

The temperature will stay the same.

The ice cube will freeze the water.

A basketball is sitting at the edge of a table. If it falls off, what type of energy transformation occurs as it falls and hits the ground?

Potential to kinetic to thermal

Kinetic to potential to thermal

Thermal to kinetic to potential

Chemical to kinetic to potential

A student observes that a puddle of water disappears on a sunny day. Which process is responsible for this change, and what energy transformation is involved?

Evaporation; thermal energy from the sun causes liquid water to become gas

Freezing; kinetic to potential energy

Condensation; thermal to potential energy

Melting; potential to kinetic energy

A person slides down a playground slide. Explain how both potential and kinetic energy are involved in this process.

The person has potential energy at the top, which changes to kinetic energy as they slide down.

The person has kinetic energy at the top and potential energy at the bottom.

The person only has kinetic energy throughout.

The person only has potential energy throughout.

A pot of water is heated on a stove. Describe how heat is transferred from the stove to the water and then throughout the water.

Heat is transferred by conduction from the stove to the pot, and then by convection within the water.

Heat is transferred by radiation from the stove to the water.

Heat is transferred only by conduction throughout.

Heat is transferred only by convection throughout.

A student places a cold metal spoon in a bowl of hot soup. After a few minutes, the spoon becomes warm. Explain why this happens in terms of heat transfer.

Heat moves from the soup to the spoon by conduction.

Heat moves from the spoon to the soup by conduction.

Heat moves from the air to the spoon by convection.

Heat moves from the soup to the spoon by radiation.
