Honors WPE Flashcard

Front

What type of energy do we get from our food?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food, which our bodies convert into usable energy.

Front

At which point is potential energy greatest?

Back

Potential energy is greatest at the highest point in a system, where the object has the most stored energy due to its position.

Front

What is being transferred as you do work?

Back

Energy is transferred when work is done, as it involves the movement of an object against a force.

Front

Energy that is stored is called...

Back

Potential energy is the energy stored in an object due to its position or state.

Front

When a pendulum swings, at which point is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing, where the pendulum is moving fastest.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

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 work in physics?

Back

Work is defined as the process of energy transfer that occurs when an object is moved over a distance by an external force.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground, calculated as PE = mgh.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.
