Contact vs Non contact forces

Front

What are contact forces?

Back

Forces that occur when two objects are physically touching each other, such as friction, tension, and normal force.

Front

What are non-contact forces?

Back

Forces that act on an object without physical contact, such as gravity, magnetism, and electric forces.

Front

What happens when like poles of magnets are brought together?

Back

The magnets repel (push apart).

Front

What are the two poles of a magnet called?

Back

North and South Pole.

Front

What are the three main non-contact forces?

Back

Gravity, electricity, and magnetism.

Front

What is gravity?

Back

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

Front

What is magnetism?

Back

A force that can attract or repel certain materials, typically associated with magnets.

Front

What is the electric force?

Back

A force that occurs between charged objects, which can be attractive or repulsive depending on the charges.

Front

What is the normal force?

Back

The support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.

Front

How does distance affect electric force?

Back

As distance increases, the electric force decreases.
