Work, Power, and Energy Flashcard

Front

What is the formula for calculating kinetic energy?

Back

KE = 0.5 * m * v^2, where m is mass and v is velocity.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

How does mass affect kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object; as mass increases, kinetic energy increases.

Front

What is gravitational potential energy (GPE)?

Back

The energy an object possesses due to its height above the ground and its mass.

Front

What factors affect gravitational potential energy?

Back

GPE depends on an object's height above the ground and its mass.

Front

What does it mean for energy to be conserved?

Back

Energy cannot be created or destroyed; it can only change forms.

Front

What is the relationship between work and energy?

Back

Work is done when energy is transferred to or from an object.

Front

What is the formula for calculating work?

Back

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

Front

If no movement occurs, how much work is done?

Back

0 J; work requires displacement.

Front

What is the unit of energy in the International System of Units (SI)?

Back

Joule (J).
