Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is often associated with the height of an object above the ground.

Front

What factors affect potential energy?

Back

Potential energy depends on the mass of the object and its height above the ground. The formula is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing, where the speed of the pendulum is greatest.

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, calculated using the formula KE = 1/2 mv².

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases as mass increases, assuming velocity remains constant. More mass means more energy is required to move the object.

Front

What does a graph showing kinetic energy and mass indicate?

Back

A graph showing kinetic energy versus mass typically indicates that kinetic energy increases as mass increases, assuming velocity is constant.

Front

What is the difference between an atom and a molecule?

Back

An atom is the smallest unit of an element, while a molecule is a group of two or more atoms bonded together.

Front

What does the diagram of oxygen and nitrogen represent?

Back

The diagram represents one molecule of oxygen (O2) and one molecule of nitrogen (N2), indicating the combination of these gases.

Front

What is the formula for calculating potential energy?

Back

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

Front

Which object has greater potential energy: one with high mass or one with high height?

Back

An object with both high mass and high height will have the greatest potential energy, as both factors contribute to the energy stored.
