Conservation of Energy

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

What type of energy does an object have when it is in motion?

Back

Kinetic energy.

Front

What type of energy is associated with an object's position or height?

Back

Potential energy.

Front

When a ball is at the top of a hill, what type of energy is it primarily storing?

Back

Potential energy.

Front

What happens to potential energy as an object rolls down a hill?

Back

The potential energy decreases as it is converted into kinetic energy.

Front

Which letter in a diagram typically represents the point where kinetic energy is at its maximum?

Back

D.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed of the object.

Front

At which points in a motion diagram does an object have both kinetic and potential energy?

Back

At points B, C, E, and F.

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 the acceleration due to gravity, and h is height.
