According to Newton's Second Law of Motion, what is the formula for net force?

• Net force = mass + acceleration

• Net force = mass / acceleration

• Net force = mass - acceleration

• Net force = mass * acceleration

What does Newton's First Law of Motion state about an object in motion?

• It will stay in motion unless acted upon by a net force

• It will change direction unless acted upon by a force

• It will accelerate continuously

• It will eventually stop on its own

What did the hovercraft lab demonstrate about balanced forces?

• An object will have a constant velocity

• An object will change its velocity

• An object will accelerate

• An object will stop moving

What is another name for Newton's First Law of Motion?

• Law of Acceleration

• Law of Force

• Law of Motion
