Energy Transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. An example is water falling down a waterfall.

Front

What type of energy do we receive from the Sun?

Back

We receive light and heat energy from the Sun.

Front

What is the first step in the energy transformation process of photosynthesis in plants?

Back

The first step is the absorption of light energy from the Sun.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.

Front

What is the order of energy transformations in photosynthesis?

Back

The order is light energy → chemical energy.

Front

What energy transformations occur in a lamp when it is turned on?

Back

The energy transformations are electrical energy → thermal energy → light energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.

Front

What energy transformation occurs when water turns a turbine in a dam?

Back

The transformation is mechanical energy → electrical energy.

Front

What is the role of a generator in energy transformation?

Back

A generator converts mechanical energy into electrical energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.
