Contact and Noncontact forces

Front

What are contact forces?

Back

Forces that occur when two objects are physically touching each other.

Front

What are non-contact forces?

Back

Forces that act on an object without physical contact, such as gravitational force.

Front

Give an example of a contact force.

Back

Friction, tension, and normal force are examples of contact forces.

Front

What is friction?

Back

A force that opposes the motion of an object, acting in the direction opposite to the movement.

Front

What is a contact pull?

Back

A force exerted through a rope or string when two objects are pulling on each other.

Front

What is a contact push?

Back

A force exerted when two objects are pushing against each other.

Front

How do contact forces differ from non-contact forces?

Back

Contact forces require physical interaction, while non-contact forces do not.

Front

What is an example of a non-contact force?

Back

Gravity is an example of a non-contact force.

Front

What happens to the force of gravity as distance increases?

Back

The force of gravity decreases as the distance between two objects increases.

Front

What is tension in physics?

Back

The force transmitted through a string, rope, or wire when it is pulled tight.
