What else can I help you with?
Which example best illustrates a change from elastic potential energy to kinetic energy?
A ball dropped from a height transforms its stored elastic potential energy due to gravity into kinetic energy as it accelerates downward.
What type of energy transforms when a ball rolling off a table top and bouncing on floor until it stops?
The potential energy of the ball (due to its position on the table) transforms into kinetic energy as it rolls off the table and falls. When the ball hits the floor, some of the kinetic energy transforms into elastic potential energy as the ball compresses and then rebounds. Finally, friction and air resistance gradually dissipate the ball's kinetic energy into thermal energy, causing it to stop.
Is kinetic energy conserved in an elastic collision?
Yes, kinetic energy is conserved in an elastic collision, meaning the total kinetic energy before the collision is equal to the total kinetic energy after the collision.
What forms of energy are in stretched elastic?
In stretched elastic, the primary forms of energy present are elastic potential energy, which is the energy stored in the elastic material due to its deformation, and kinetic energy, if the elastic material is moving.
Is elastic energy the total potential and kinetic energy in a system?
Elastic energy specifically refers to the potential energy stored in an elastic material when it is stretched or compressed. It does not include kinetic energy, which is the energy of motion. In a system, the total energy would be the sum of both potential and kinetic energy.

How does an elastic power car work?
Elastic cars work by converting elastic potential energy into kinetic energy. The most potential energy, the more kinetic energy.

The energy in earthquake is kinetic energy or potential energy?
The energy in an earthquake is primarily released as seismic waves, which are a combination of kinetic and potential energy. As tectonic plates undergo stress and strain, they accumulate potential energy in the form of stored elastic energy. When this energy is suddenly released, it transforms into kinetic energy, causing the ground to shake.

Elastic energy is the total potential and kinetic energy in a system?
No. For example a falling stone is converting potential energy of gravitational attraction into kinetic energy, and there is no elastic energy.
What are the three forms of mechanical energy?
The three forms of mechanical energy are kinetic energy, potential energy, and elastic energy. Kinetic energy is the energy an object possesses due to its motion, potential energy is the energy that is stored in an object due to its position or condition, and elastic energy is the energy stored in elastic materials when they are stretched or compressed.
Describe the role of energy transformation in the production of electricity?
Heat energy (as steam or hot gas) transforms to kinetic energy through the turbine. The kinetic energy transforms into electricity through the rotor of the electric generator.
When a bus brakes to a stop its kinetic energy transforms?
When a bus brakes to a stop, its kinetic energy transforms into heat energy due to friction between the brake pads and the wheels. This heat energy is dissipated into the surroundings.
Does kinetic energy and elastic potential energy have anything in common?
Yes, kinetic energy and elastic potential energy are both forms of mechanical energy. Kinetic energy is the energy of an object in motion, while elastic potential energy is the energy stored in an object due to its deformation (stretching or compressing). Both forms of energy can be converted into other types of energy and are related through the conservation of energy principle.
