What is an applied force?

Back

An 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 friction that occurs when air pushes against a moving object, causing it to decelerate.

Front

What is a frictional force?

Back

A frictional force is a force that opposes the motion of an object when it is in contact with another surface.

Front

What does the normal force do?

Back

The normal force acts perpendicular to the surface of contact and supports the weight of an object resting on a surface.

Front

What is weight force?

Back

Weight force is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity.

Front

What is tension force?

Back

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

Front

What is drag force?

Back

Drag force is a resistance force that acts opposite to the direction of motion of an object moving through a fluid (like air or water).

Front

What is buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on an object that is submerged in it, counteracting the weight of the object.

Front

What is the relationship between normal force and weight force?

Back

The normal force typically balances the weight force when an object is resting on a horizontal surface.

Front

What factors affect frictional force?

Back

Frictional force is affected by the nature of the surfaces in contact and the normal force acting between them.
