Physical Science- Energy

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground, calculated as the product of its mass, the height, and the acceleration due to gravity.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 times the mass of the object times the square of its velocity (KE = 1/2 mv²).

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is the total kinetic energy of the particles in an object.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system, representing the total energy available for doing work.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, which can be converted into kinetic energy.

Front

How is potential energy transformed into kinetic energy?

Back

Potential energy is transformed into kinetic energy when an object falls or moves from a higher position to a lower position, such as a ball dropped from a height.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the mass of the object, the height above the ground, and the acceleration due to gravity.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is directly proportional to the square of the velocity; if the velocity doubles, the kinetic energy increases by a factor of four.
