Exploring the Four Fundamental Forces

What is the primary effect of gravity on objects near the Earth's surface?

• It causes objects to repel each other.

• It causes objects to fall towards the Earth.

• It causes objects to move in a circular path.

• It causes objects to become weightless.

Which of the following best describes the electromagnetic force?

• It acts only over very short distances.

• It is responsible for holding the nucleus of an atom together.

• It is the force between charged particles.

• It is weaker than the gravitational force.

What is the role of the strong nuclear force?

• It binds electrons to the nucleus.

• It holds the protons and neutrons together in the nucleus.

• It causes radioactive decay.

• It is responsible for the attraction between masses.

Which force is responsible for the process of beta decay in radioactive materials?

• Gravitational force

• Electromagnetic force

• Strong nuclear force

• Weak nuclear force

Which of the following correctly ranks the fundamental forces from strongest to weakest?

• Electromagnetic, strong nuclear, weak nuclear, gravitational

• Strong nuclear, electromagnetic, weak nuclear, gravitational

• Gravitational, electromagnetic, weak nuclear, strong nuclear

• Weak nuclear, strong nuclear, electromagnetic, gravitational

How does gravity affect the motion of planets in the solar system?

• It causes them to move in straight lines.

• It keeps them in elliptical orbits around the Sun.

• It causes them to spin on their axes.

• It has no effect on their motion.

Which of the following is an application of the electromagnetic force?

• The orbit of the Moon around the Earth

• The binding of protons and neutrons in the nucleus

• The operation of electric motors

• The decay of radioactive isotopes

What is a common application of the strong nuclear force?

• Generating electricity in nuclear power plants

• Creating magnetic fields

• Powering solar panels

• Driving chemical reactions

Which fundamental force is primarily responsible for the structure of atoms?

• Gravitational force

• Electromagnetic force

• Strong nuclear force

• Weak nuclear force

In what way does the weak nuclear force differ from the strong nuclear force?

• It acts over longer distances.

• It is responsible for holding the nucleus together.

• It is involved in processes like beta decay.

• It is stronger than the electromagnetic force.
