SPS8: Force, Mass & Motion Preassessment

Mechanical advantage is the ratio of:

• Work input to work output

• Force input to force output

• Speed input to speed output

• Distance input to distance output

Newton's First Law of Motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This is also known as the law of:

• Inertia

• Acceleration

• Action and reaction

• Momentum

The relationship between force, mass, and acceleration is described by which law of motion?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Law of Inertia
