Net Force

Front

What is net force?

Back

The net force is the total force acting on an object after all the forces are combined, taking into account their directions.

Front

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

Back

Add the magnitudes of the forces together.

Front

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

Back

Subtract the smaller force from the larger force and take the direction of the larger force.

Front

What is the unit of force?

Back

Newton (N)

If Mrs. King and Mr. King push a dresser with 30N to the left and there is 10N of friction to the right, what is the net force?

Back

20N Left

Front

In a tug-of-war, if group A pulls with 250N to the left and group B pulls with 400N to the right, which way will the ribbon move?

Back

The ribbon will move to the right and group B will win.

Front

What is a force?

Back

A force is a push or pull that can cause movement.

Front

If the force of gravity on an object is 10N down and the normal force is 10N up, what is the net force?

Back

0N

Front

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

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.
