Net Force

Front

What is the definition of net force?

Back

Net force is the vector sum of all the individual forces acting on an object, determining the object's acceleration.

Front

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

Back

You add the magnitudes of the two forces together.

Front

What happens to the net force when two equal forces act in opposite directions?

Back

The net force is zero, and the object does not move.

Front

If a person exerts a force of 50 N upward and gravity exerts a force of 15 N downward, what is the net force?

Back

The net force is 35 N upward.

Front

What is the unit of measurement for force?

Back

The unit of measurement for force is the Newton (N).

Front

What is the effect of a net force of zero on an object?

Back

An object with a net force of zero will either remain at rest or continue to move at a constant velocity.

Front

If two forces of 20 N and 15 N are acting in opposite directions, what is the net force?

Back

The net force is 5 N in the direction of the larger force.

Front

What is the relationship between net force and acceleration according to Newton's second law?

Back

Net force is equal to mass times acceleration (F = ma).

Front

How does increasing mass affect acceleration if the net force is constant?

Back

Increasing mass will decrease acceleration if the net force remains constant.

Front

What is the significance of direction in net force calculations?

Back

Direction is crucial in net force calculations because forces are vector quantities; forces in opposite directions must be subtracted.
