Non-Contact Forces

Front

What are non-contact forces?

Back

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

Front

What is the law of universal gravitation?

Back

It states that every mass attracts every other mass in the universe, and the force of attraction depends on the masses and the distance between them.

Front

What determines the strength of gravitational force between two objects?

Back

The mass of the objects and the distance between them.

Front

What is gravity?

Back

A non-contact force that pulls objects toward each other, primarily experienced as the force that pulls objects toward the Earth.

Front

What is air resistance?

Back

A type of frictional force that opposes the motion of an object through the air.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational pull between objects.

Front

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

Back

Contact forces require physical interaction between objects, while non-contact forces act at a distance.

Front

What is an example of a non-contact force?

Back

Gravity, magnetism, and electrostatic forces are all examples of non-contact forces.

Front

What happens to two objects with opposite electric charges?

Back

They attract each other.

Front

What happens to two objects with the same electric charge?

Back

They repel each other.
