The diagram shows a cart moving freely along a track. What happens to the energy of the cart as it moves from point A to point B on the diagram?
Potential energy is transformed to kinetic energy.
Kinetic energy is transformed to potential energy.
Both potential energy and kinetic energy stay the same.
Which diagram models the position of a soccer ball when it has the greatest amount of gravitational potential energy?
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Energy was destroyed during certain steps in the experiment.
The steps in the experiment required more energy than was available.
The experiments created energy that was then used up at a faster rate.
Some energy was transformed into unwanted heat or sound that was not detected.
A hockey player uses her stick to hit a hockey puck. Which statement describes the overall energy transfer?
Energy is transferred from the stick to the puck.
Energy is transferred from the player to the puck.
Energy is transferred from the puck to the player.
Energy is transferred from the stick to the player.
The energy efficiency shown in this Sankey diagram is:
About 10%.
About 30%.
About 60%.
Impossible to tell.
What is the difference between energy transfer and transformation?
They are the same
Transfer is energy moving to a different location. Transformation is energy changing forms.
Transfer is energy changing forms. Transformation is energy moving to a different location.
