Work, Power and Energy Flashcard Review

Front

What is potential energy?

Back

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

Front

How does height affect potential energy?

Back

An object's potential energy increases with increasing height, as potential energy is directly proportional to height.

Front

Where is potential energy at its minimum?

Back

Potential energy is at its minimum at the lowest point of an object's position, often referred to as point X in diagrams.

Front

What is the unit of measurement for power?

Back

The unit used to measure power is the Watt.

Front

What is work in physics?

Back

Work is defined as the process of energy transfer that occurs when an object is moved in the direction of the applied force.

Front

What is the unit of measurement for energy?

Back

The unit of measurement for both potential and kinetic energy is Joules.

Front

What is kinetic energy?

Back

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

Front

How is power calculated?

Back

Power is calculated as the rate at which work is done or energy is transferred, expressed as P = W/t, where W is work and t is time.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy, either increasing or decreasing its kinetic or potential energy.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
