Net Forces

Front

What is a net force?

Back

The net force is the overall force acting on an object when all the individual forces acting on it are combined. It determines the object's acceleration.

Front

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

Back

You add the magnitudes of the forces together.

Front

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

Back

You subtract the smaller force from the larger force.

Front

If a skateboarder pushes forward with a force of 25 N and the wind pushes back with a force of 8 N, what is the net force?

Back

The net force is 17 N forward (25 N - 8 N).

Front

What happens to the speed of an object if the net force acting on it is zero?

Back

The object's speed remains constant.

Front

What is the effect of a net force acting in the opposite direction of an object's motion?

Back

The object's speed will decrease.

Front

If two forces of 10 N and 5 N are acting in the same direction, what is the net force?

Back

The net force is 15 N in that direction.

Front

What is the net force if a 10 N force acts to the right and a 4 N force acts to the left?

Back

The net force is 6 N to the right (10 N - 4 N).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a force of 3 N acts to the left and a force of 3 N acts to the right, what is the net force?

Back

The net force is 0 N.
