Changes in energy when a child slides down a slide?

Answer 1

At the top of the slide, the child has a bunch of potential energy. Potential energy becomes converted to kinetic energy as the child accelerates down the slide. At the bottom of the slide, your science teacher will say that all potential energy is converted to kinetic.

If your looking to be more technical, some kinetic energy will become heat along the length of the slide via friction. At the end of the slide, the child has to stop right? When the child lands on his feet, or face, the inelastic collision between his feet or face and the sand would produce more heat from kinetic energy. Then he will have neither potential nor kinetic energy, the heat he created would be dissipated into the air, sand, and slide as if everything is back to normal. But he might have some cuts and bruises if he did slide down face first.

Answer 2

The gravitational potential energy of the skier is converted into kinetic energy of the skier. Due to friction, part of his kinetic energy is converted into internal of the skier's shoes, snow and air.

Answer 3

When the sled ('sled' refers to the sled and the child here) is at the top of the hill it has potential energy. As the sled travels down the hill, the potential energy turns into kinetic (movement) energy.

(In a real-world application, some of the kinetic energy is transferred into thermal (heat) energy because of friction. Because the friction between a sled and snow is not very high, this energy conversion is often ignored.)

Answer 4

gravitational potential energy because the child is a the top, then i changes to heat energy because of the friction then, then it goes to kinetic energy ..........im a beast

Answer 5

At the top of the hill, the sled has potential energy because it is not moving. The reaction of the sled to the elevation and the force of gravity working on the sled is kinetic.

Answer 6

Kinetic energy decreases and potential energy increases

Answer 7

energy to sound
