Energy Transformation Study Guide

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. An example is photosynthesis, where plants convert sunlight into chemical energy.

What type of energy is represented by the gears of a bicycle?

Back

The gears of a bicycle represent mechanical energy, which is the energy associated with the motion and position of an object.

Front

What must be true about the winds in Texas for wind energy production?

Back

The winds in Texas must blow most of the time to effectively produce wind energy.

Front

Which of the following is not a form of energy: A) Kinetic B) Potential C) Thermal D) Friction?

Back

D) Friction is not a form of energy; it is a force that opposes motion.

Front

What energy transformation occurs when sanding wood with sandpaper?

Back

The energy transformation that occurs when sanding wood is from mechanical energy to heat energy.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion, which depends on the mass and velocity of the object.

Front

Define potential energy.

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy or elastic potential 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 is an example of mechanical energy in everyday life?

Back

An example of mechanical energy is a moving car, which has kinetic energy due to its motion and potential energy due to its position.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which is related to temperature.
