6.8A Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

At what point does an object have the greatest potential energy on an inclined plane?

Back

At the highest point of the incline.

Front

How does potential energy change as an object moves down an incline?

Back

As the object moves down, its potential energy decreases while its kinetic energy increases.

Front

What happens to the total energy of a system when potential energy is converted to kinetic energy?

Back

The total energy remains constant; energy is conserved.

Front

In a roller coaster, where is the potential energy the greatest?

Back

At the highest points of the track.

Front

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

Back

At the highest points, potential energy is maximum and kinetic energy is minimum; at the lowest point, kinetic energy is maximum and potential energy is minimum.

Front

When is potential energy at its maximum during a free fall?

Back

When the object is at its highest point before falling.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.
