Nathan notices that when the bag moves away from him, it swings upward. Then, it slows to a stop and then swings back. Nathan knows that the _____ energy of the bag is converted to gravitational potential energy as the bag swings upward.

kinetic

potential

thermal

elastic

Answer explanation

The correct choice is kinetic because as the bag moves away from Nathan, it has kinetic energy which is then converted to gravitational potential energy as it swings upward.

A student learning about heat transfer makes this claim:

Some metals change temperature more rapidly than others.

The student will test this claim using metal rods made of iron and copper.

What other lab materials would be useful?

prism, heat lamp, screen, meter stick

beaker, digital scale, stopwatch, clamps

litmus paper, beaker, balance, battery

hot water, pan, stopwatch, thermometer

Answer explanation

The correct choice is hot water, pan, stopwatch, thermometer as they are essential for conducting an experiment to compare the rate of temperature change in iron and copper rods.

MULTIPLE CHOICE QUESTION

Media Image

Nathan lost his balance when he hit the bag with a hard punch. He says that was because of the reaction force from his punch, which was large because the bag is heavy. Is he correct?

Yes, he is correct.

No, it is not the weight, it is the large mass of the bag that gives the large reaction force.

No, the reaction force depends on the force of Nathan's punch, not on the mass of the bag.

No, the bag does not exert a reaction force, because it is flexible.

Answer explanation

The correct choice is 'No, the reaction force depends on the force of Nathan's punch, not on the mass of the bag.' The reaction force is determined by the force applied, not the mass of the bag.
