Calculating Net Force

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

You add the magnitudes of the forces together.

Front

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

Back

You subtract the smaller force from the larger force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What force pulls objects towards the Earth?

Back

Gravity pulls objects down towards the Earth.

Front

If Mrs. Jones pulls a rope with 73 N and a student pulls with 47 N in the same direction, what is the net force?

Back

The net force is 120 N in the direction of the pull.

Front

If two forces of 30 N and 20 N are acting in opposite directions, what is the net force?

Back

The net force is 10 N in the direction of the larger force.

Front

What happens to the net force if no forces are acting on an object?

Back

If no forces are acting on an object, the net force is 0 N.

Front

What is the net force if an object is pushed with 45 N to the right and 5 N to the left?

Back

The net force is 40 N to the right.

Front

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

Back

An object with a net force of 0 N will remain at rest or continue moving at a constant velocity.
