At which point in the roller coaster ride is mechanical kinetic energy at a maximum?
D
The diagram shows a child swinging on a swing set.
As the child moves from left to right, at which point will the maximum kinetic energy be reached?
2
The battery in a flashlight eventually stopped working. Does that mean the energy disappeared?
NO!
The energy in the battery did not disappear. It was transformed into electrical energy and radiant energy in the flashlight.
A hydroelectric plant uses the power of falling water to turn turbines to create electricity to power homes, offices, and schools.
Where is the potential energy to run the plant?
1
2 meteors are falling into Earth’s atmosphere. One weighs 25kg and the other weighs 55kg. They both hit the Earth at the same time. Compare the kinetic energy of the two meteors.
There would be more kinetic energy in the 55kg meteor.
The drawing shows a waterfall flowing into a pool of water.
Which statement best describes the energy of the objects in the drawing?
The water has potential energy at the top of the waterfall and increasing kinetic energy as it falls.
A person running down the sidewalk has this type of energy.
(Mechanical) kinetic energy.
energy that is stored in the nucleus of all atoms
