Energy Transformations

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in an object when it is stretched or compressed, such as in a spring or rubber band.

Front

What transformation occurs when food is converted into energy for physical activity?

Back

The transformation is from chemical energy (in food) to mechanical energy (used for movement).

Front

What type of energy do plants convert from sunlight during photosynthesis?

Back

Plants convert radiant energy (sunlight) into chemical energy (food) during photosynthesis.

Front

What type of energy is released in a nuclear explosion?

Back

A nuclear bomb converts nuclear energy into kinetic, sound, light, and thermal energy.

Front

What is the process of converting chemical energy into mechanical energy in living organisms?

Back

This process occurs during cellular respiration, where glucose (chemical energy) is converted into ATP (usable energy for mechanical work).

Front

Define 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 above the ground.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.

Front

What is an example of energy transformation in a battery-powered device?

Back

In a battery-powered device, chemical energy stored in the battery is transformed into electrical energy, which then powers the device.

Front

What type of energy transformation occurs in a hydroelectric power plant?

Back

In a hydroelectric power plant, gravitational potential energy of water is transformed into mechanical energy (movement of turbines), which is then converted into electrical energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, often experienced as heat.
