6.8A Potential and Kinetic Energy Questions

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

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy due to the gravitational force acting on it.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed. If the speed doubles, the kinetic energy increases by four times.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

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

Back

In a roller coaster, potential energy is highest at the top of the hills, and kinetic energy is highest at the lowest points.

Front

When is potential energy at its maximum for a skateboarder?

Back

Potential energy is at its maximum when the skateboarder is at the top of the ramp.

Front

When is kinetic energy at its maximum for a falling object?

Back

Kinetic energy is at its maximum just before the object hits the ground.

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.

Front

How does energy transform when a child slides down a slide?

Back

As the child slides down, potential energy is converted into kinetic energy.
