Homework Statement

Give a clear example of:
a,) the conversion of elastic potential energy to Kinetic energy.

What elasticky thing can you stretch to propel something?

b.) the conversion of elastic potential energy to GPE

If you stretch that elasticky thing and propel something how do you give it gravitational potential energy?

c.) the conversion of chemical potential energy to KE

What kind of energy is released in a violent, sudden chemical reaction? How would you give kinetic energy to something with that energy?

d.) the conversion of chemical potential energy to thermal energy

When you cause an energetic chemical reaction to occur what usually is the result? Can you think of an example of such a reaction?

e.) the conversion of electromagnetic energy to KE

What kinds of electrical/magnetic devices cause things to move

f.) The conversion of KE to GPE

I will let you figure this one out on your own.

I think you know all these things. Have a little more confidence in yourself. You can do these.

No problem, I can help you with these examples!

a) An example of the conversion of elastic potential energy to kinetic energy is a bouncing ball. When the ball is dropped from a height, it has elastic potential energy due to its position above the ground. As it falls, this energy is converted into kinetic energy, which is the energy of motion. The ball will continue to bounce up and down, converting between elastic potential energy and kinetic energy until it eventually comes to a stop.

b) A common example of the conversion of elastic potential energy to gravitational potential energy is a stretched rubber band. When a rubber band is stretched, it has elastic potential energy due to its stretched position. If the rubber band is then released, it will snap back to its original shape, converting its elastic potential energy into gravitational potential energy as it rises into the air.

c) An example of the conversion of chemical potential energy to kinetic energy is a battery-powered toy car. The chemical potential energy stored in the battery is converted into electrical energy, which is then used to power the motor of the car. The motor then converts this electrical energy into kinetic energy, causing the car to move.

d) One example of the conversion of chemical potential energy to thermal energy is a campfire. The chemical potential energy stored in the wood is converted into thermal energy through the process of combustion. This thermal energy can then be used to cook food or keep people warm.

e) A common example of the conversion of electromagnetic energy to kinetic energy is a solar-powered car. The solar panels on the car convert electromagnetic energy from the sun into electrical energy, which is then used to power the motor and move the car.

f) The conversion of kinetic energy to gravitational potential energy can be seen in a roller coaster. As the roller coaster car reaches the top of a hill, it has a high amount of kinetic energy due to its speed. As it goes over the top of the hill, this kinetic energy is converted into gravitational potential energy as it gains height. This potential energy is then converted back into kinetic energy as the car moves down the next hill.
