Contact & Noncontact Forces Test Review

Front

What keeps the planets in orbit around the sun?

Back

Gravity is the force that keeps the planets in orbit around the sun.

Front

What is a contact force?

Back

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

Front

What can force cause?

Back

Force can cause an object to accelerate, slow down, remain in place, or change shape.

Front

What type of force is magnetic force?

Back

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

Front

What type of force is gravity?

Back

Gravity is a non-contact force.

Front

Define non-contact force.

Back

A non-contact force is a force that acts on an object without physical contact, such as gravity or magnetic force.

Front

Define contact force.

Back

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

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.

Front

What is an example of a non-contact force?

Back

An example of a non-contact force is gravitational force.

Front

What happens when two objects exert equal and opposite forces on each other?

Back

They are in a state of equilibrium, and there is no net force acting on them.
