Types of Forces

Front

What is friction?

Back

Friction is a force that resists motion between two surfaces in contact.

Front

What type of force is air resistance?

Back

Air resistance is a type of friction that occurs when air pushes against a moving object, causing it to decelerate.

Front

What force acts in the ropes of a swing?

Back

The force acting in the ropes of a swing is called tension.

Front

What force ultimately slows a roller coaster to a stop?

Back

Friction is the force that ultimately slows a roller coaster to a stop.

Front

What is gravitational force?

Back

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

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 the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding over each other.

Front

How does surface area affect friction?

Back

Surface area can affect friction; however, for most surfaces, increasing the area does not significantly increase friction.

Front

What is the role of friction in everyday life?

Back

Friction allows us to walk without slipping, helps vehicles to stop, and enables objects to be held in place.
