Energy Unit - Mastery Check

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the pendulum's swing.

Front

What type of energy is stored in an object due to its position?

Back

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

Front

What happens to energy during a transformation?

Back

During a transformation, energy changes from one form to another, such as from potential energy to kinetic energy.

Front

What type of energy is present in an acorn hanging from an oak tree?

Back

The acorn has potential energy due to its position above the ground.

Front

What is the relationship between electrical energy and heat energy in an electric kettle?

Back

In an electric kettle, electrical energy is transformed into heat energy to heat the water.

Front

When does a baseball have the greatest gravitational potential energy?

Back

A baseball has the greatest gravitational potential energy when it reaches its highest point in the air.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its height above the ground, calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does the height of an object affect its potential energy?

Back

The potential energy of an object increases as its height above the ground increases.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
