Forces Review

Front

What are Contact Forces?

Back

Contact forces are forces that occur when two objects are physically touching each other. Examples include friction, tension, and air resistance.

Front

What are Non-Contact Forces?

Back

Non-contact forces are forces that act on an object without physical contact. Examples include gravitational force, magnetic force, and electrostatic force.

Front

What unit is used to measure force?

Back

The unit used to measure force is the Newton (N).

Front

What is a vector?

Back

A vector is a quantity that has both direction and magnitude, often represented by an arrow.

Front

What does 'magnitude' refer to in the context of forces?

Back

Magnitude refers to the size or strength of a force, measured in Newtons.

Front

What does 'direction' refer to in the context of forces?

Back

Direction refers to the line along which a force acts, indicating where the force is applied.

Front

What is air resistance?

Back

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

Front

Is air resistance a contact or non-contact force?

Back

Air resistance is a contact force because it acts on an object when it is moving through the air.

Front

What is friction?

Back

Friction is a contact force that opposes the motion of two surfaces sliding past each other.

Front

What is tension?

Back

Tension is a pulling force transmitted through a string, rope, or cable when it is pulled tight.
