Work and Energy Flashcard

Front

What is the law of conservation of energy?

Back

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

Front

At which point is kinetic energy greatest in a pendulum swing?

Back

At the lowest point of the swing.

Front

What is energy?

Back

Energy is the ability to do work.

Front

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

Back

At the lowest point of the swing.

Front

When a pendulum swings, at which point is potential energy at its greatest?

Back

At the highest point of the swing.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion.

Front

Define potential energy.

Back

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

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does energy transform in a pendulum?

Back

Energy transforms between kinetic and potential energy as the pendulum swings.
