Unit 5: Work & Energy

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, often related to height or configuration.

Front

What is kinetic energy?

Back

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

Front

What is the formula for calculating potential energy?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the relationship between work and energy?

Back

Work is done when a force causes an object to move, resulting in a transfer of energy.

Front

What must happen for work to be done on an object?

Back

The object must move in the direction of the applied force.

Front

What type of energy transformation occurs when wood burns?

Back

Stored chemical energy is transformed into thermal energy and light.

Front

What two variables most influence potential energy?

Back

Mass and height.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.
