Universal forces

Front

What is the weak nuclear force?

Back

The weak nuclear force is one of the four fundamental forces in nature, responsible for processes like beta decay in atomic nuclei. It acts over a very short range.

Front

What are the four universal forces?

Back

The four universal forces are gravitational force, electromagnetic force, weak nuclear force, and strong nuclear force.

Front

What is the gravitational force?

Back

Gravitational force is the attraction between two masses. It is the force that keeps planets in orbit around the sun.

Front

What is the electromagnetic force?

Back

The electromagnetic force is the force between charged particles. It can both attract and repel, depending on the charges involved.

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. It is the strongest of the four forces but acts over a very short range.

Front

What is the weak nuclear force responsible for?

Back

The weak nuclear force is responsible for certain types of radioactive decay, such as beta decay, where a neutron changes into a proton.

Front

What is centripetal force?

Back

Centripetal force is a center-directed force that keeps an object moving in a circular path by constantly changing its direction.

Front

How does distance affect universal forces?

Back

The strength of universal forces, such as gravitational and electromagnetic forces, decreases with increasing distance between the objects.

Front

What are artificial satellites?

Back

Artificial satellites are man-made objects that are launched into orbit around the Earth or other celestial bodies for purposes like communication, weather monitoring, and scientific research.

Front

What is an example of a force that can both attract and repel?

Back

Electric and magnetic forces can both attract and repel objects, depending on their charges or magnetic poles.
