Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object does not accelerate.

What is an example of a contact force?

Back

Friction is an example of a contact force.

Front

What is an example of a non-contact force?

Back

Gravity is an example of a non-contact force.

How does mass affect the force needed to accelerate an object?

Back

The greater the mass of an object, the more force is needed to accelerate it.

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration (F = ma).
