A roller coaster starts at the top and moves down the hill. When the roller coaster is at the bottom, which statement is true?
The roller coaster has more potential energy
The roller coaster creates kinetic energy
The roller coaster car has more kinetic energy
The roller coaster destroys kinetic energy
Andre is boiling water to cook pasta. The diagram below shows some of the changes that occur when water is heated and boiled. These changes involve both energy transfers and energy transformations.
What is the difference between an energy transfer and an energy transformation?
Transformation is movement of energy from one place to another, and transfer is the change of one type of energy to another.
There is no difference. Both involve movement of energy from one place to another.
There is no difference. Both involve the change of one type of energy to another.
Transfer is movement of energy from one place to another or from one object to another, and transformation is the change of one type of energy to another.
Joanna took her little brother to the playground because he likes to swing. Look at the diagram below that shows Joanna pushing her brother on a swing. Which statement is true about the transformation between kinetic and potential energy while the boy swings?
(A is on the left.B is the bottom middle. C is on the right.)
Potential energy changes to kinetic energy between points B and C.
Potential energy changes to kinetic energy between points A and B.
Kinetic energy changes to potential energy between points A and B.
