When a pendulum is released, it swings back and forth. It will continue moving without any additional push until it is slowed by friction from the air around it. Use the illustration below to answer the following question.
At which point does the pendulum weight have the greatest amount of kinetic energy?
Position 3. Because it has transferred most if its potential energy into kinetic.

Every moving object has kinetic energy. This illustration shows four vehicles. Assume that they are all traveling at the same speed on a highway.
What do you know about the kinetic energy of the vehicles?
The delivery van has the greatest kinetic energy because its mass is greater than that of the other vehicles.

Kylie drew this illustration to show what happens when a weight on a spring is pulled down and then released. Position 1 shows the spring at the start of the experiment. Position 2 shows how it looked when the weight was pulled downward. Position 3 shows what happened when she released the spring. Position 4 shows the spring just before the weight started to fall back down.
At which point does the spring have the greatest amount of mechanical energy?
The mechanical energy in all of them is the same.

Students made an electromagnet by wrapping a wire in loops around an iron nail and attaching the wire to a battery, as shown in the illustration below.
The students conducted a test to learn how the number of wire loops affected the number of paper clips held by the electromagnet. The table below shows the results of the test.
Based on the information in the table, which of the following is the best conclusion?
Adding more wire loops makes an electromagnet stronger.
