Work and Energy Flashcard

Front

What does gravitational potential energy depend on?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

If Bobby and Carol lift the same book to the second floor, who does more work?

Back

They did the same amount of work.

Front

What is the formula for work in terms of kinetic energy?

Back

W = ΔKE

Front

How do you calculate the change in kinetic energy (ΔKE)?

Back

ΔKE = KE_f - KE_i

Front

What is the total energy of a system if it is given as 14 J?

Back

The total energy of the system is 14 J.

Front

What is the kinetic energy (KE) halfway down if it is given as 7,500 J?

Back

The KE halfway down is 7,500 J.

Front

Define work in the context of physics.

Back

Work is defined as the energy transferred to or from an object via the application of force along a displacement.

Front

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

Back

The unit of work is the Joule (J).

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy.

Front

What is kinetic energy (KE)?

Back

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