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

Back

You subtract the smaller force from the larger force.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What happens to an object when 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 the relationship between net force and motion?

Back

Net force determines the motion of an object; it can cause an object to start moving, stop moving, or change direction.

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object.

Front

What is the formula for calculating net force?

Back

Net Force = Force1 + Force2 + ... + ForceN.
