Net Force Practice

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

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

Back

Add the magnitudes of the forces together. For example, if 5 N and 3 N act to the right, the net force is 8 N to the right.

Front

How do you calculate net force when two forces act 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 net force if a 10 N force to the right and a 4 N force to the left are acting on an object?

Back

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

Front

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

Back

If the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a box is pushed with a force of 15 N to the right and a force of 10 N to the left, what is the net force?

Back

The net force is 5 N to the right (15 N - 10 N = 5 N right).

Front

What is the net force on an object with a 20 N force to the left and a 20 N force to the right?

Back

The net force is 0 N (20 N left - 20 N right = 0 N).

Front

What does it mean if the net force is positive?

Back

A positive net force indicates that the object is accelerating in the direction of the positive force.

Front

What does it mean if the net force is negative?

Back

A negative net force indicates that the object is accelerating in the direction opposite to the positive force.
