• Grassy field, gym floor, concrete sidewalk, soccer ball, meter stick

• Soccer ball, bowling ball, beach ball, stopwatch, meter stick

• 4-foot-tall student, 4½-foot-tall student, 5-foot-tall student, soccer ball, meter stick

Picking up a heavy box is much more difficult than putting it down. What is a likely explanation for this?

• Pushing force is more difficult to accomplish than pulling force.

• The force of gravity acts against you when you try to push something to the ground.

• The action is less difficult because nothing is pulling the object toward the ground.

• The force of gravity is pulling the box toward the ground which makes the action of putting the box down easier to do.

The force of friction was less on the left so the box moved to the right. What can be said about the effect of the force being applied by the above student on the left?

• The force of magnetism was greater on the left so the box moved to the right.

• The pull of gravity was greater on the right so the box moved to the right.

• The pushing force was greater on the left so the box moved to the right.

• The force of friction was less on the left so the box moved to the right.

Some students are designing an experiment to test the effect of force on an object. The force they are testing is friction. The students will investigate how far a car will slide when rolled across surfaces with different textures. The cars all have equal masses. Which of the following experimental procedures would be the best one for the students to use to conduct the above investigation?

• First, create a ramp for each of the textures to be tested. Then, create a table to record your data. Next, roll each car down each ramp one time. Measure the distance the car traveled, and record the measurement in your table.

• First, create a ramp for each of the textures to be tested. Make sure that all the ramps are the same height and length. Next, roll each car down each ramp three times. Each time, measure the distance the car traveled.

A student wanted to test the effect of friction on a toy car rolling down a ramp. She has constructed the ramp with five lanes, each covered with a textured material. She rolled a toy cart down each lane and used a timing device to measure the length of time it took the cart to reach the end of the ramp. Her results are shown in the chart below. What conclusion could the student make based on this experiment?

• The force of friction is greatest on the wood.

• The force of friction is least on the sandpaper.

• The force of friction is least on the tile.

• The force of friction is not affected by material.

Students were asked to list observations of the uses of energy in the classroom. One student's list is provided below. Which observations listed above involved the use of electrical energy?

• Observations 1, 2, and 4

• Observations 3, 4, and 6

• Observations 1, 3, and 5

• Observations 1, 4, and 6

A student designed the circuit above. Which switches should the student close to produce sound energy only?

• Switch 1

• Switch 4

• Switch 3

• Switch 2

A student designed the circuit above. What would most likely happen if the student closed Switch 1, Switch 2, and Switch 4?

• Bulb A would light up and the bell would ring, but bulb B would not light up.

• Bulb B would light up, but bulb A would not light up and the bell would not ring.

• Neither of the bulbs would light up, and the bell would not ring.

• Both of the bulbs would light up, but the bell would not ring.

Observe the diagram above. How many bulbs would turn on if a student closed switch C and switch D?

• 0

• 1

• 2

• 3
