Unit 3 Test: Four Fundamental forces

Front

What is gravity?

Back

Gravity is a force of attraction between any two objects with mass.

Front

What is an example of gravity's effect on Earth?

Back

The orbit of the Moon around the Earth.

Front

What is nuclear fission?

Back

Nuclear fission is the process where a neutron hits a large nucleus, splitting it into smaller pieces and releasing energy.

Front

What is the difference between electromagnetism and gravity?

Back

Electromagnetism can be a force of attraction or repulsion, while gravity is only a force of attraction.

Front

Rank the four fundamental forces of nature from weakest to strongest.

Back

Gravity, Weak Nuclear, Electromagnetism, Strong Nuclear.

Front

What causes gravity?

Back

Gravity is caused by the pull between any objects with mass.

Front

What is the strong nuclear force?

Back

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

Front

What is the weak nuclear force?

Back

The weak nuclear force is responsible for the process of beta decay in radioactive elements.

Front

What is electromagnetism?

Back

Electromagnetism is a fundamental force that causes the interaction between charged particles.

Front

What is an example of a force of repulsion?

Back

The repulsion between two like charges (e.g., two positive charges).
