Front

What happens when forces are unbalanced?

Back

The object will accelerate.

Front

What is a contact force?

Back

A force that requires physical contact between two objects.

Front

What is an unbalanced force?

Back

Forces that cause an object to accelerate because they are not equal in size and opposite in direction.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

If a box is at rest and all forces acting on it are balanced, what will happen?

Back

The box will remain at rest.

Front

What is the effect of a net force of 0 N on an object?

Back

The object will not accelerate; it will either remain at rest or continue moving at a constant speed.

Front

What is the direction of the net force if an object is pushed with 400 N to the right and 400 N to the left?

Back

The net force is 0 N.
