Calculating Net Force Test Review

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

How do you calculate net force when two forces are acting in the same direction?

Back

Add the magnitudes of the forces together. For example, if 10 N and 5 N are acting to the right, the net force is 15 N to the right.

Front

How do you calculate net force when two forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force. The direction of the net force is in the direction of the larger force.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What is a balanced force?

Back

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

Front

If a box is pushed with a force of 20 N to the right and a frictional force of 5 N acts to the left, what is the net force?

Back

The net force is 15 N to the right.

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 the unit of force?

Back

The unit of force is the Newton (N).

Front

If two people push a car with forces of 50 N and 30 N in the same direction, what is the net force?

Back

The net force is 80 N in the direction they are pushing.

Front

If a force of 10 N is applied to the left and a force of 15 N is applied to the right, what is the net force?

Back

The net force is 5 N to the right.
