Net Force

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined. It determines the object's motion.

Front

If two forces are equal and opposite, what is the net force?

Back

The net force is 0 N, meaning there is no change in motion.

Front

What unit is used to measure force?

Back

The unit to measure force is Newton (N).

Front

In a tug-of-war, if one team pulls with a greater force, what happens to the rope?

Back

The rope will move in the direction of the team pulling with the greater force.

Front

If a person lifts a box with a force of 50 N and gravity pulls it down with 30 N, what is the net force?

Back

The net force is 20 N upward.

Front

What is the normal force?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

How do you calculate net force when friction is involved?

Back

Net force = applied force - frictional force.

Front

If a car is pushed with a force of 100 N to the right and friction is 40 N to the left, what is the net force?

Back

The net force is 60 N to the right.

Front

What happens to the net force if two people push a dresser in the same direction?

Back

The net force is the sum of the forces they apply.

Front

If an object is at rest and no net force acts on it, what will happen?

Back

The object will remain at rest.
