Work, Energy, & Power Review Period 3

Front

What is the definition of potential energy?

Back

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

Front

At which point is potential energy greatest in a gravitational field?

Back

Potential energy is greatest at the highest point in a gravitational field.

Front

What is the metric unit for work?

Back

The metric unit for work is Joules.

Front

What is the formula for calculating work?

Back

Work is calculated using the formula: Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is kinetic energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

What is power in the context of work and energy?

Back

Power is defined as the rate at which work is done or energy is transformed.

Front

What is the metric unit for power?

Back

The metric unit for power is Watts.

Front

How is power calculated?

Back

Power is calculated using the formula: Power = Work / Time.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.
