26 Potential and Kinetic Energy ASSIGNMENT

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and speed.

Front

What factors affect kinetic energy?

Back

Kinetic energy is dependent on mass and speed.

Front

How is potential energy converted to kinetic energy?

Back

Potential energy is converted to kinetic energy when an object moves from a higher position to a lower position, such as a roller coaster descending a hill.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What happens to energy in a frictionless system?

Back

In a frictionless system, energy is conserved; potential energy converts to kinetic energy without loss.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

If a cat has 400 joules of kinetic energy and moves at 10 m/s, what is its mass?

Back

The mass of the cat is 8 kg.

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.
