Which of the following describes the best way to test the strength of several different magnets?

Count the number of paperclips each magnet picks up.

Place each magnet in water to observe if it sinks or floats.

Use a triple beam balance to mass each magnet.

Measure the length and width of each magnet with a meter stick

A student sets up an experiment using the ramp below to test how friction would affect how far a car would travel after leaving a ramp. In order for the student to test the effect of friction on a rolling car, which of the following variables would need to be changed?

the type of surface on which the car rolls

Which of the following is a question about forces that could be tested in a classroom investigation?

How does the height of a ramp affect how far a car rolls?

A student wants to test the force of magnetism by placing objects on top of a piece of cardboard and then moving them with a magnet placed under the cardboard. Which items will help the student with this investigation?

A nail, a paper clip, and a iron filings

A paper clip, a thumbtack, and a toothpick

A paper clip, a piece of paper, and iron filings

A piece of foil, iron filings, and a nail

A student is conducting an experiment on magnets. The picture below shows the student holding magnet 2 and pushing it towards magnet 1. Which of the following will most likely happen to magnet 1 as magnet 2 is moved closer?

Magnet 1 will move away from magnet 2.

Magnet 1 will move under magnet 2.

Magnet 1 will move toward magnet 2.

Magnet 1 will move on top of magnet 2.

Students in a science class are conducting an investigation to determine the amount of force needed to move a 10 kg mass. Their teacher instructed them to conduct the investigation 3 times and record their data with each trial. Why would the teacher want the students to do the investigation more than one time?

To increase the reliability of their results

To help them understand their results

So they could practice their procedure

Class time was too long to only do the investigation once

Some students predicted that a tennis ball would bounce higher than a golf ball. They conducted one test and found out that the golf ball bounced higher. What should they do to find out if their prediction was correct?

Repeat the test several more times.

Replace the golf ball with a baseball.

Agree that the first test was accurate.

Drop the balls from a higher position.

A student wants to test the force of magnetism by placing objects on top of a piece of cardboard and then moving them with a magnet placed under the cardboard. Which items will help the student with this investigation?

A nail, a paper clip, and a thumbtack

A paper clip, a thumbtack, and a toothpick

A paper clip, a penny, and iron filings

A piece of foil, iron filings, and a nail

What can force do to an object?

Have the object remain in place

Jupiter has about 317 times more mass than Earth. What can you infer from this fact?

That Jupiter’s gravitational force is much stronger than Earth’s gravitational force.

That Jupiter’s gravitational force is much weaker than on Earth’s gravitational force.

That Jupiter’s and Earth’s gravitational forces are equal.

Mass has no effect on the gravitational force between two objects
