A train sits at the top of a hill and then rolls down onto the track. What has happened to the energy in this scenario?

The energy transferred from the ramp to the car

What are the three requirements for work to occur?

A force is applied to an object

The object moves in the direction of the force

Zach is bowling at the bowling alley. He rolls the ball at pins in the distance and tries to make them fall.. How is energy transferred in the process?

Zach first generates kinetic energy and transfers it to the ball when it is thrown. As the ball hits the pins, some of the kinetic energy is transferred to the pins, which then falls.

Zach first generates potential energy and transfers it to the ball when it is rolled. The ball generates kinetic energy in the rolling and transfers all of the kinetic energy to the pins, which then falls.

Zach first generates kinetic energy and transfers it to the ball when it is rolled. As the ball hits the pins, only potential energy is transferred to the pins, causing them to fall .

Zach first generates potential energy and transfers it to the ball when it is rolled. As the ball hits thepins, some of the potential energy is transferred to the pins, causing them to fall.

Charles picks up a heavy object and lifts it in the air, he then puts it back down on the ground. When is he not doing any work?

when he held the object before placing it back on the ground

when he puts the object on the ground

The graph below shows the relationship between the mass of an object and its gravitational potential energy. What can be concluded from the graph?

Gravitational potential energy increases with mass

There is no relationship between mass and gravitational potential energy

Gravitational potential energy is independent of mass

Which 2 choices would provide mechanical energy?

kinetic energy from any movement

potential energy based on position

Analyze the image of a child riding a sled down a snow-covered hill. Which statement correctly describes the energy transformation in the picture?

The child/sled have the greatest kinetic energy at the lowest point of the hill while the sled is still accelerating.

The child/sled have the greatest potential energy at the lowest point of the hill while the sled is still accelerating.

The child/sled have equal amounts of potential and kinetic energy midway down the hill. Which student, if any, is correct?

All of the potential energy is transformed into thermal energy as the child/sled accelerate down the hill
