Potential vs. Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a ball held at a height has potential energy because of its position above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has. For example, a ball held at 3 meters has more potential energy than a ball held at 1 meter.

Front

Can kinetic energy be converted to potential energy?

Back

Yes, kinetic energy can be converted to potential energy. For example, when you throw a ball upwards, its kinetic energy is converted to potential energy as it rises.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of an object. This means that if the mass increases, the kinetic energy also increases.

Front

What are indicators that an object has energy?

Back

Light, sound, heat, and motion are indicators that an object has energy.

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 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 potential energy when an object falls?

Back

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

Front

What type of graph represents the relationship between kinetic energy and mass?

Back

The relationship between kinetic energy and mass is represented by a linear graph.
