kinetic energy

Answer 1

When an object is in motion, it possesses kinetic energy.

Answer 2

An object’s gravitational potential energy depends on the object’s mass, the strength of the gravitational field, and what other variable?(1 point)
Responses

the speed of the object
the speed of the object

the shape of the object
the shape of the object

the object's height from the ground
the object's height from the ground

the color of the object

Answer 3

An object’s gravitational potential energy depends on the object’s mass, the strength of the gravitational field, and the object's height from the ground.

Answer 4

If you are at an amusement park and you ride a slingshot, how does your potential energy compare to your kinetic energy at the top of the shot?

(1 point)
Responses

The kinetic energy is less than potential energy.
The kinetic energy is less than potential energy.

The kinetic energy is twice the amount of potential energy.
The kinetic energy is twice the amount of potential energy.

The kinetic energy and potential energy are the same.
The kinetic energy and potential energy are the same.

Kinetic energy is greater than potential energy.

Answer 5

At the top of the shot on a slingshot ride, the kinetic energy is less than potential energy. At that point, the ride has maximum potential energy and minimal kinetic energy before it begins to descend.

Answer 6

Rebecca climbs the ladder of a large water slide, waits her turn at the top, and then slides down the slide into a pool. Which answer best describes the energy changes during her time on the slide?(1 point)
Responses

potential → kinetic → potential
potential → kinetic → potential

kinetic → mechanical → potential
kinetic → mechanical → potential

kinetic → potential → kinetic
kinetic → potential → kinetic

potential → mechanical → kinetic

Answer 7

The best answer that describes the energy changes during Rebecca's time on the slide is potential → kinetic → potential.

She starts with potential energy at the top, converts it to kinetic energy as she slides down, and when she reaches the bottom and is momentarily in the water, some of that kinetic energy can convert back to potential energy depending on the height of her position in the water. However, the primary focus is on the conversion from potential at the top to kinetic during the slide down.

Answer 8

Kim is upstairs, but walks downstairs to the kitchen for a snack. Which statement correctly describes the types of energy she has at the top of the stairs and as she walks down the stairs?(1 point)
Responses

kinetic energy at the top of the stairs; potential energy as she walks down
kinetic energy at the top of the stairs; potential energy as she walks down

potential energy at the top of the stairs; kinetic energy as she walks down
potential energy at the top of the stairs; kinetic energy as she walks down

potential energy at the top of the stairs; potential energy as she walks down
potential energy at the top of the stairs; potential energy as she walks down

kinetic energy at the top of the stairs; kinetic energy as she walks down
kinetic energy at the top of the stairs; kinetic energy as she walks down

Answer 9

The correct statement is potential energy at the top of the stairs; kinetic energy as she walks down.

At the top of the stairs, Kim has potential energy due to her height above the ground, and as she walks down, that potential energy is converted to kinetic energy as she moves.

Answer 10

The picture below shows a pinwheel that Bobby has in his front yard.

Often Bobby sees his pinwheel spinning, but other times it does not spin. Which statement best explains what makes his pinwheel spin?

(1 point)
Responses

The Sun heats up the pinwheel, causing it to turn.
The Sun heats up the pinwheel, causing it to turn.

The colors on the wheel repel one another, causing it to turn.
The colors on the wheel repel one another, causing it to turn.

Energy from the ground shakes the wheel causing the pinwheel to move.
Energy from the ground shakes the wheel causing the pinwheel to move.

Energy from the wind pushes on the wheel causing the pinwheel to move.

Answer 11

The statement that best explains what makes Bobby's pinwheel spin is Energy from the wind pushes on the wheel causing the pinwheel to move.

Pinwheels typically turn when wind blows against them, using the force of the moving air to create motion.
