Contact and non contact forces

Front

What is a non-contact force?

Back

A non-contact force is a force that acts between two objects that are not touching each other.

Front

What are contact forces?

Back

Contact forces are forces that occur when two objects are in physical contact with each other.

Front

Name three examples of contact forces.

Back

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

Front

Who is known for studying gravity and formulating the laws of motion?

Back

Isaac Newton is the scientist known for studying gravity and formulating the laws of motion.

Front

What type of force is gravity?

Back

Gravity is a non-contact force.

Front

What force pulls objects towards the Earth?

Back

The force that pulls objects towards the Earth is gravity.

Front

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

Back

Contact forces require physical contact between objects, while non-contact forces act at a distance without physical contact.

Front

Give an example of a non-contact force other than gravity.

Back

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

Front

What role does friction play in contact forces?

Back

Friction is a contact force that opposes the motion of an object sliding or rolling over a surface.

Front

How does gravity affect objects on Earth?

Back

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