A man is driving a car. He slows down to stop at a stop sign. When does the car have the most motion energy (kinetic energy)?

When the car's speed is 30 miles per hour

When the car's speed is 15 miles per hour

When the car's speed is 0 miles per hour

The car's motion energy is the same the whole time.

Two birds are moving at the same speed. The birds have different amounts of kinetic energy. Which of the following must be true?

The birds have different masses.

The birds have different shapes.

The birds are made of different materials.

How does increasing the speed of an object affect the kinetic energy of the object?

Increasing the speed of an object increases its kinetic energy.

Increasing the speed of an object decreases its kinetic energy.

Increasing the speed of an object does not affect its kinetic energy.

Whether or not its kinetic energy is affected depends on how much its speed was increased.

UFO 1 and UFO 2 are traveling at the same speed, but the kinetic energy of UFO 1 is greater than the kinetic energy of UFO 2. Does UFO 1 weigh more than, less than, or the same as UFO 2?

Object 1 weighs more than Object 2.

Object 1 weighs less than Object 2

Object 1 weighs the same as Object 2.

More information is needed to compare the weights of the objects.

Two pine cones are falling from a pine tree. Both pine cones are falling at the same speed. If Pine Cone 1 weighs less than Pine Cone 2, which pine cone has more kinetic energy?

Pine Cone 2 has more kinetic energy.

Pine Cone 1 has more kinetic energy.

Both pine cones have the same amount of kinetic energy.

Neither pine cone has any kinetic energy.

A student has two identical springs. He stretches one spring and compresses the other spring. Which of the following describes the elastic energy of the springs while they are being stretched or compressed?

Both the compressed spring and the stretched spring have elastic energy

The compressed spring has elastic energy, but the stretched spring does not.

The stretched spring has elastic energy, but the compressed spring does not.

Neither the compressed spring nor the stretched spring has elastic energy.

What type of energy does the skater possess when he is at the greatest height on the track as shown in the picture above?

Gravitational and Kinetic Energy

What type of energy does the skater possess as he is moving up the track as shown in the picture above?

Gravitational and Kinetic energy

Bocaj builds a model roller coaster with three hills, as shown in the diagram. He places a toy car at the top of the first hill and releases it. The car stops at point X. Which change to the model would allow the toy car to travel over all three hills?

Order the three hills from tallest to shortest to provide the gravitational energy needed for the car to make it over each hill.

Add a loop before the first hill in order to maximize the kinetic energy of the car.

Add a loop after the tallest hill in order to maximize the kinetic energy of the car.

Order the three hills from shortest to tallest so that the gravitational energy builds up according to the height of each hill.
