Unit 5: Forces at a Distance Review

Front

What type of radioactive decay gives off energy only (no particles)?

Back

Gamma decay is a type of radioactive decay that emits energy in the form of gamma rays without releasing particles.

Front

What is the symbol for beta particles?

Back

The symbol for beta particles is β.

Front

What can be either a force of attraction or repulsion?

Back

Electromagnetism can be either a force of attraction or repulsion.

Front

What is the only force of attraction?

Back

Gravity is the only force of attraction.

Front

What charge do beta particles have?

Back

Beta particles have a -1 charge.

Front

In nuclear fission, what happens to the mass of the products compared to the original mass?

Back

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

Front

What is the force of attraction between two masses called?

Back

The force of attraction between two masses is called gravity.

Front

What is the force that acts at a distance without contact?

Back

Forces at a distance include gravitational, electromagnetic, and nuclear forces.

Front

What is the principle behind electromagnetic forces?

Back

Electromagnetic forces arise from the interaction of charged particles.

Front

What is the difference between alpha and beta decay?

Back

Alpha decay emits alpha particles (2 protons and 2 neutrons), while beta decay emits beta particles (electrons or positrons).
