Energy Transformations and Conservation of Energy

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as electrical energy to thermal energy.

Front

What is the law of conservation of energy?

Back

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

Front

What type of energy does a microwave oven primarily transform electrical energy into?

Back

A microwave oven primarily transforms electrical energy into thermal energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and velocity.

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

How do plants transform energy from the sun?

Back

Plants transform energy from the sun into chemical energy through the process of photosynthesis.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

How can friction be reduced?

Back

Friction can be reduced by decreasing the contact between surfaces, using lubricants, or smoothing surfaces.

Front

What happens to total energy when an object moves in a closed system?

Back

In a closed system, the total energy remains constant, even as it transforms between different forms.
