Chapter 14 Review

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting two atoms to create heat energy.

Front

How does a coal-fired power plant produce electricity?

Back

A coal-fired power plant produces electricity by burning coal to heat water and produce steam, which then drives a turbine connected to a generator.

Front

Give an example of an object with high potential energy.

Back

A book placed on a high shelf.

Front

What happens to energy in a simple pendulum?

Back

In a simple pendulum, potential energy is converted to kinetic energy and vice versa as the pendulum swings.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula KE = 0.5 * mass * velocity^2.

Front

What is the kinetic energy of a 6 kg object moving at 3 m/s?

Back

27 J.

Front

Define potential energy.

Back

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

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy increases with the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.

Front

Explain energy transformation in a roller coaster.

Back

In a roller coaster, potential energy is highest at the top of the hill and is converted to kinetic energy as it descends.

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.
