Front

What are the four fundamental forces in nature?

Back

1. Gravitational Force 2. Electromagnetic Force 3. Weak Nuclear Force 4. Strong Nuclear Force

Front

What is gravitational force?

Back

The force of attraction between any two objects with mass.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases with the square of the distance between two objects.

Front

What happens to the gravitational force if the distance between two objects is tripled?

Back

The gravitational force becomes 1/9 as much.

Front

What is nuclear fission?

Back

A nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing energy.

Front

What happens to the mass during nuclear fission?

Back

The mass of the products decreases slightly compared to the original mass.

Front

What is a practical application of nuclear fission?

Back

Nuclear reactors are a practical application of nuclear fission.

Front

What is electromagnetic force?

Back

The force that acts between charged particles, responsible for electricity and magnetism.

Front

What is the weak nuclear force?

Back

A fundamental force responsible for the process of beta decay in atomic nuclei.

Front

What is the strong nuclear force?

Back

The force that holds protons and neutrons together in the nucleus of an atom.
