Unit 3 Test "Review" Energy

Front

What is Newton's First Law of Motion?

Back

An object in motion stays in motion unless acted upon by an external force.

Front

What is potential energy?

Back

Energy stored in an object due to its position, such as a rock at the edge of a cliff.

Front

What energy transformation occurs in a hydroelectric dam?

Back

Mechanical energy is transformed into electrical energy.

Front

What is kinetic energy?

Back

The energy of an object in motion, such as a rolling ball.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass.

Front

What is the formula for kinetic energy?

Back

Kinetic energy = 1/2 * mass * velocity^2.

Front

What is gravitational potential energy?

Back

Potential energy related to an object's height above the ground.

Front

What is the relationship between force and motion?

Back

Force causes an object to accelerate, change direction, or change shape.

Front

What is the law of conservation of energy?

Back

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

Front

What is an example of mechanical energy?

Back

The energy possessed by an object due to its motion or position.
