gpe and ke relationship quiz

Section Quiz: Conservation of Energy. Write the letter of the correct a, the sum of kinetic energy and gravitational potential energy. b. the sum of kinetic energy. Results 1 - 24 of Quiz - Gravitational Potential (GPE) & Kinetic Energy (KE) (3 Quiz Set) the relationship between mass, height, and kinetic energy Relative. Aug 4, Play this quiz and learn difference between potential and kinetic energy.

When potential energy is used it is converted into kinetic energy. You can think of potential energy as kinetic energy waiting to happen. The green ball has potential energy due to its height.

Work done, Kinetic energy & GPE - A-level & GCSE Physics

The purple ball has kinetic energy due to its velocity. A Car on a Hill We can compare potential and kinetic energy by considering a car on a hill.

When the car is at the top of the hill it has the most potential energy. If it is sitting still, it has no kinetic energy. As the car begins to roll down the hill, it loses potential energy, but gains kinetic energy.

The potential energy of the position of the car at the top of the hill is getting converted into kinetic energy. Gravitational Potential Energy One type of potential energy comes from the Earth's gravity. This is called gravitational potential energy GPE.

gpe and ke relationship quiz

Gravitational potential energy is the energy stored in an object based on its height and mass. To calculate the gravitational potential energy we use the following equation: The height is determined based on the height the object could potentially fall.

Kinetic energy vs. Potential energy

The height may be the distance above the ground or perhaps the lab table we are working on. What is the potential energy of a 2 kg rock sitting at the top of a 10 meter high cliff?

gpe and ke relationship quiz

If friction and air resistance are ignored, the kinetic energy changes by an amount that is equal to the work done by the applied force. Friction and air resistance reduce the amount of kinetic energy by transferring it into heat energy. The law of conservation of energy means that the work done is therefore equal to amount of heat transferred plus the kinetic energy of the object.

Kinetic energy can be stored by using a heavy wheel called a flywheel. This spins at high speed on low-friction bearings but most of the time, kinetic energy is transferred from other forms of energy only when it is needed.

gpe and ke relationship quiz

For the GCSE, you should be able to discuss the transfer of kinetic energy in particular situations. Examples might include the space shuttle re-entry or meteorites burning up in the atmosphere. It could also include braking systems as they are designed to transfer kinetic energy into heat energy to slow or stop a vehicle.

Forces - Kinetic Energy of Objects

Most vehicles currently use non-renewable fossil fuels as the source of energy that is transferred into kinetic energy. As humans are becoming more aware of the damage caused to the Earth by large scale burning of fossil fuels, car manufacturers are designing electric cars.

There are even cars that produce their electricity from solar cells, some is used to charge the batteries and the rest is transferred directly into kinetic energy without first being stored. These do not emit give out gases into the atmosphere but the electrical energy needs to come from somewhere.
