Net Forces Review

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate or change its motion because the forces acting on it are not equal in size and opposite in direction.

Front

What is the net force when two forces act in the same direction?

Back

The net force is the sum of the two forces acting in the same direction.

Front

What is the net force when two forces act in opposite directions?

Back

The net force is the difference between the two forces, acting in the direction of the larger force.

Front

What is gravity?

Back

Gravity is a force that pulls two objects towards one another.

Front

What is the unit of force?

Back

The unit of force is called a Newton (N).

Front

What is net force?

Back

The overall force acting on an object after all the forces are combined.

Front

What happens to an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

If a couch is pushed with 35 N to the right and 25 N to the right, what is the net force?

Back

The net force is 60 N to the right.

Front

What is the effect of an unbalanced force on an object?

Back

An unbalanced force causes an object to accelerate, change direction, or change shape.
