Thermal Energy and Transformations

Front

What does the law of conservation of energy state?

Back

The total amount of energy in the universe remains constant.

Front

How does potential energy change as a boulder rolls down a hill?

Back

Potential energy decreases.

Front

How does kinetic energy change as a boulder rolls down a hill?

Back

Kinetic energy increases.

Front

At which position does a ball have the greatest kinetic energy and the least potential energy?

Back

Position 2.

Front

What is the relationship between temperature and molecular movement?

Back

As temperature increases, molecules move faster.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

How does temperature affect the kinetic energy of particles in a substance?

Back

Cold substances have lower kinetic energy because particles are moving around less.

Front

What happens to the kinetic energy of a ball at the top of a hill compared to the bottom?

Back

At the top, kinetic energy is lower; at the bottom, it is higher.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.
