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 are the two main types of forces?

Back

Contact forces and non-contact forces.

Front

Define contact forces.

Back

Contact forces are forces that occur when two objects are physically touching each other.

Front

Define non-contact forces.

Back

Non-contact forces are forces that act on an object without physical contact, such as gravitational, magnetic, and electric forces.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, occurring when two surfaces are in contact.

Front

What is tension?

Back

Tension is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a stable surface.

Front

What is applied force?

Back

Applied force is a force that is applied to an object by a person or another object.

Front

What is air resistance?

Back

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