ICP 4 Net Force Practice

Front

What is net force?

Back

Net force is the sum of all forces acting on an object, capable of accelerating a mass.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If two forces act in the same direction, how do you calculate the net force?

Back

Add the magnitudes of the forces together.

Front

If two forces act in opposite directions, how do you calculate the net force?

Back

Subtract the smaller force from the larger force.

Front

What is the net force when a 10 N force to the right and a 4 N force to the left are applied?

Back

The net force is 6 N to the right.

Front

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

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

How does friction affect net force?

Back

Friction reduces the net force acting on an object when it opposes the applied force.

Front

Calculate the net force if a student pushes a box with 30 N to the right and friction is 10 N to the left.

Back

The net force is 20 N to the right.

Front

What is the net force if a 50 N force pulls to the left and a 30 N force pulls to the right?

Back

The net force is 20 N to the left.
