Contact/Non Contact Forces and Gravity

Front

What is a contact force?

Back

A contact force is a force that requires physical contact between two objects, such as friction, tension, and normal force.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts at a distance without physical contact, such as gravitational force, magnetic force, and electrostatic force.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What happens when you push the north end of a magnet towards the south end?

Back

They will attract each other.

Front

What is static electricity?

Back

Static electricity is an imbalance of electric charges within or on the surface of a material, which can cause a non-contact force.

Front

What type of force is responsible for making a compass work?

Back

Magnetic force.

Front

What is the gravitational pull?

Back

Gravitational pull is the force exerted by a mass that attracts other masses towards it.

Front

What is an example of a non-contact force?

Back

Charge from static electricity.

Front

What type of force do opposite charges create when brought near each other?

Back

A non-contact force (forces at a distance).

Front

What is friction?

Back

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