Energy Flashcard 1

Front

What is the unit of work?

Back

Joule

Front

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

Back

At the highest point (W).

Front

How do you calculate work done when lifting an object?

Back

Work (W) is calculated using the formula W = F × D, where F is the force applied and D is the distance moved in the direction of the force.

Front

What is the definition of energy?

Back

Energy is the ability to do work.

Front

What type of energy is associated with an object's position or condition?

Back

Potential energy.

Front

What is kinetic energy?

Back

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

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy (PE) is calculated using the formula PE = m × g × h, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy of that object.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.
