IPC Review Kinetic and Potential Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

At which point is potential energy greatest in a roller coaster ride?

Back

At the highest point of the ride.

Front

What happens to kinetic energy as the speed of an object increases?

Back

The kinetic energy increases.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

When is kinetic energy highest in a pendulum swing?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

What is the relationship between potential energy and kinetic energy in a closed system?

Back

In a closed system, the total mechanical energy (potential + kinetic) remains constant, meaning as potential energy decreases, kinetic energy increases and vice versa.

Front

How is gravitational potential energy calculated?

Back

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

Front

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

Back

The unit of energy is the Joule (J).

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and its velocity.

Front

Explain the concept of energy conservation in the context of kinetic and potential energy.

Back

Energy conservation states that energy cannot be created or destroyed, only transformed from one form to another, such as from potential energy to kinetic energy.
