Energy transfers and transformations

Front

What is the process by which plants convert sunlight into chemical energy?

Back

Photosynthesis.

Front

What type of energy transformation occurs when rubbing your hands together?

Back

Kinetic energy is transformed into thermal energy due to friction.

Front

What type of energy travels in waves and can move through empty space?

Back

Radiant energy (or light energy).

Front

What is the relationship between the speed of an object and its kinetic energy?

Back

The faster an object moves, the more kinetic energy it possesses.

Front

What is mechanical energy?

Back

The total energy of an object due to its motion (kinetic energy) and its position or condition (potential energy).

Front

Define kinetic energy.

Back

The energy an object possesses due to its motion.

Front

Define potential energy.

Back

The energy stored in an object due to its position or condition.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of energy transformation in a hydroelectric power plant?

Back

Potential energy of water is transformed into kinetic energy as it flows, which is then converted into electrical energy.

Front

What is thermal energy?

Back

The energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.
