Newton's Laws Introduction

What is Newton's First Law of Motion primarily about?

• Action and reaction forces

• The relationship between force, mass, and acceleration

• The tendency of an object to resist changes in its state of motion

• The calculation of gravitational force

Which equation represents Newton's Second Law of Motion?

• F_g = mg

• E = mc^2

• F = ma

• A = F/F

What is the difference between mass and weight?

• Mass is measured in Newtons, while weight is measured in kilograms.

• Mass is the amount of matter in an object, while weight is the force of gravity on an object.

• Mass changes depending on gravity, while weight remains constant.

• Mass and weight are two different terms for the same physical quantity.

What does Newton's Third Law of Motion state?

• An object at rest stays at rest unless acted upon by a force.

• The net force on an object is equal to its mass times its acceleration.

• For every action, there is an equal and opposite reaction.

• Gravity is the only force acting on a falling object.

A box is suspended motionless by a rope. If the box weighs 5 Newtons, what is the tension force in the rope?

• Less than 5 Newtons.

• Exactly 5 Newtons.

• More than 5 Newtons.

• Cannot be determined without knowing the rope's mass.

If the net force acting on an object is NOT zero, what will happen to the object?

• It will remain at rest.

• It will move at a constant velocity.

• It will accelerate.

• It will lose mass.
