Net Forces Review

Front

What is net force?

Back

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

Front

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

Back

You add the magnitudes of the two forces together.

Front

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

Back

You subtract the smaller force from the larger force.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What happens to an object when the net force is zero?

Back

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

What is motion?

Back

Motion is the change of position of an object over time relative to a reference point.

Front

What is relative motion?

Back

Relative motion is the calculation of the motion of an object with regard to another object.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).
