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 acceleration and direction.

Front

What does it mean if an object has a zero net force?

Back

An object with a zero net force can be at rest or moving at a constant velocity.

Front

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

Back

You add the magnitudes of the two forces together.

Front

If a force of 5 N is acting south and a force of 78936 N is acting north, what is the net force?

Back

The net force is 78931 N to the north.

Front

What is the net force if a car has a force of 54 N forwards and brakes apply a force of 73 N backwards?

Back

The net force is 19 N forwards.

Front

What is the direction of net force if the forces are balanced?

Back

The net force is zero, meaning there is no direction.

Front

What happens to an object's motion if the net force is not zero?

Back

If the net force is not zero, the object will accelerate in the direction of the net force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If two forces of 10 N and 15 N are acting in opposite directions, how do you find the net force?

Back

You subtract the smaller force from the larger force: 15 N - 10 N = 5 N in the direction of the larger force.

Front

What is the net force when a 20 N force to the right and a 20 N force to the left are applied?

Back

The net force is 0 N, as the forces cancel each other out.
