Q2 Checkpoint: Motion, Transfer of Energy, and Electrical Energy

A student watches a basketball roll toward a volleyball. The volleyball is not moving. Each ball's energy of motion is shown in the graph (see picture). Then, the basketball collides with the volleyball and makes a sound. The volleyball starts to roll. The basketball keeps rolling, but it is slower than before. Which graph shows the energy of motion of each ball after the collision?

A student goes to a bowling alley. She rolls a heavy bowling ball. The ball hits the bowling pins. What observation shows the energy changes when the ball hits the bowling pins?

• When the ball hits the pins, the pins do not move.

• When the ball hits the pins, there is a loud noise.

• When the ball hits the pins, the ball stops moving immediately.

• When the ball hits the pins, the crash produces a light.

A student places a toy car in front of a spring and marks a point X, as shown in the picture. The student pushes the toy car back, squeezing the spring different amounts. Then, the student releases the car. This is done four different times. The student records how long it takes the toy car to reach point X for each trial (look at the table). During which trial does the toy car have the most energy?

• Trial 1
• Trial 2

• Trial 3

• Trial 4

The white cue ball is hit and travels toward the red and white ball. The white cue ball contains energy as it is moving. What will happen to this energy when it collides with the red and white ball?

• All of the energy will stay with the white cue ball.

• . All of the energy will transfer to the red and white ball.

• Most of the energy will transfer to the red and white ball. Some energy will travel into the air in the form of sound.

• Some of the energy will transfer to the red and white ball. Most of the energy will travel through the air in the form of light.

Students are investigating how energy is converted. They connect a battery to a small fan as shown in the picture. Which best describes how energy is converted in the student's investigation?

• Motion from the fan is converted into electrical energy within the battery.

• Heat energy from the fan warms up the battery.

• Chemical energy from the battery is converted into light energy.

• Electrical energy from the battery is converted into motion in the fan
