Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that do not cancel each other out, causing a change in the motion of an object.

Front

What can unbalanced forces change?

Back

Unbalanced forces can change the motion of an object.

Front

What happens when two teams pull a rope with equal force?

Back

The rope remains in the same position because the forces are balanced.

Front

What is a contact force?

Back

A contact force is a force that requires physical contact between two objects.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts at a distance, such as gravity or magnetism.

Front

Give an example of a non-contact force.

Back

Gravity is an example of a non-contact force.

Front

True or False: A basketball sitting still on the court is an example of balanced forces.

Back

True.

Front

How can unbalanced forces change the motion of an object?

Back

Unbalanced forces can change the motion of an object at rest or push/pull a moving object.

Front

What is friction?

Back

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