Contact and Noncontact forces

Front

What is a contact force?

Back

A contact force is a force that occurs when two objects are physically touching each other.

Front

What is an example of a contact force?

Back

Friction is an example of a contact force.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts on an object without physical contact.

Front

What is an example of a non-contact force?

Back

Gravity is an example of a non-contact force.

Front

How does friction affect motion?

Back

Friction opposes the motion of objects, making it harder for them to slide past each other.

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

Can you name two types of forces?

Back

Contact forces and non-contact forces.

Front

What is the role of gravity on Earth?

Back

Gravity pulls objects towards the center of the Earth, giving them weight.

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical touch, while non-contact forces act at a distance.

Front

What is an example of a force that is not a contact force?

Back

Magnetic force is an example of a non-contact force.
