At what point does a roller coaster have the most kinetic energy?
A roller coaster has the most kinetic energy at the point where it is moving at its highest speed.
At what point does a kid have the most potential energy on a swing?
A kid has the most potential energy on a swing at the highest point of the swing's arc, when they are furthest from the ground.
he data below was recorded during an investigation of the relationship between potential energy and the mass and height of an object.
Height Data
When a 2 kg weight was lifted 3 meters above the floor, it had 58.8 Joules of potential energy.When a 2 kg weight was lifted 6 meters above the floor, its potential energy doubled.
Mass Data
When a 3 kg weight was lifted 2 meters above the floor, it had 58.8 Joules of potential energy. When a 6 kg weight was lifted 2 meters above the floor, its potential energy doubled.
BEST represents the relationship between potential energy and the mass and height of an object.
