At the top of the hill the roller coaster car has potential energy and no kinetic energy but as the car goes down the hill the kinetic energy increases and the potential energy decreases. This pattern continues at every top and every bottom of each hill. A roller coaster track is built with each hill getting a little smaller each time as the car looses energy over each hill due to air resistance and friction. As the car travels along the tracks some of the kinetic energy is converted to thermal energy because of the friction.

What is the transfer of mechanical energy?

The transfer of mechanical energy occurs when work is done on an object, causing a change in its kinetic or potential energy. This transfer can happen through forces acting on an object like pushing, pulling, or lifting. In essence, mechanical energy is transferred when there is a change in the motion or position of an object.


Why do appliances need to transfer energy?

Appliances need to transfer energy in order to carry out their functions. Whether it's heating, cooling, cooking, or powering electronic components, energy transfer is necessary to enable appliances to perform the tasks they are designed for.


What are the main energy transfers that happen as a roller coaster cart travels along the track fromthe start of the ride to the end?

At the start, potential energy is converted to kinetic energy as the cart descends. Kinetic energy is then converted back to potential energy as the cart ascends a hill. Friction between the cart and the track may also cause some energy to be converted to heat.


What is the movement of energy from warmer object to a cooler object?

The movement of energy from a warmer object to a cooler object is called heat transfer. This process occurs until both objects reach a thermal equilibrium where their temperatures are equal. Heat transfer can happen through conduction, convection, or radiation.


What is the form of thermal transfer that does not require matter?

Radiation is the form of thermal transfer that does not require matter. It occurs through electromagnetic waves, such as light or infrared radiation, traveling through space and transferring heat energy. This process can happen even in a vacuum where there is no physical medium for heat transfer.

Gas is burnt to cook a meal is it an energy conversion or an energy transfer?

How does it happen? If there's a chemical change, it's energy conversion, if it's a physical change, it's energy transfer.


Can energy transfer happen between two objects when each object has the exact same energy?

When each object has the same energy, energy transfer can still occur between objects. The object with the greatest mass or traveling speed will transfer the energy.

If the kinetic energy of the coaster goes up What happen to the potential energy?

uh, down? (yes, down) The potential energy, as in a compressed spring, goes to zero as the spring is released. The potential energy (sort of) becomes the kinetic energy. (Now, I'm sure that that statement could get an argument in the physics study room in the science building, but it'll get you by...)
