6.7B 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 forces are acting in the same direction?

Back

Add the magnitudes of the forces together. For example, if two forces of 5 N and 3 N are acting to the right, the Net Force is 8 N to the right.

Front

How do you calculate Net Force when 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 the unit of force?

Back

The unit of force is the Newton (N).

Front

If a force of 10 N is acting to the right and a force of 5 N is acting to the left, what is the Net Force?

Back

The Net Force is 5 N to the right.

Front

What happens to the Net Force if two equal forces act in opposite directions?

Back

The Net Force is zero, meaning there is no change in motion.

Front

What is the significance of a Net Force of zero?

Back

A Net Force of zero indicates that an object is either at rest or moving at a constant velocity.

Front

If an object has a Net Force of 40 N, what can we infer about its motion?

Back

The object will accelerate in the direction of the Net Force.

Front

What is the formula for calculating Net Force?

Back

Net Force (F_net) = F1 + F2 + ... + Fn, where F1, F2, ..., Fn are the individual forces acting on the object.

Front

What is an example of balanced forces?

Back

If a book is resting on a table, the gravitational force pulling it down is balanced by the normal force pushing it up.
