Types of Forces

Front

What is a force?

Back

A force is a push or pull acting upon an object as a result of its interaction with another object.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object, which keeps planets in orbit around the sun.

Front

What is normal force?

Back

Normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

What is air resistance?

Back

Air resistance is a type of frictional force that opposes the motion of an object moving through the air.

Front

What is frictional force?

Back

Frictional force is the force that opposes the relative motion between two surfaces in contact.

Front

What is tension force?

Back

Tension force is the force experienced by a rope or string when it is pulled from both ends.

Front

What is electromagnetic force?

Back

Electromagnetic force is the force associated with charged particles, responsible for electricity and magnetism.

Front

What is nuclear force?

Back

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

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical contact between objects (e.g., friction, tension), while non-contact forces act at a distance (e.g., gravitational, electromagnetic).

Front

What is the role of friction in everyday life?

Back

Friction allows us to walk without slipping, enables cars to grip the road, and is essential for many mechanical processes.
