Motion and Inertia

What is Newton's First Law of Motion?

• An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

• An object will move in a circular path without any external force

• Objects in motion will stop without any external force

• An object will accelerate if no force is applied to it

According to Newton's First Law of Motion, an object at rest tends to stay at rest unless...

• an external force is applied to it

• it accelerates

• it shrinks

• it changes color

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

• Newton's Third Law

• Principle of Motion

• Law of Rest

• Law of Inertia

What is Newton's Second Law of Motion?

• Force = Mass x Acceleration

• Acceleration = Force / Mass

• Mass = Force / Acceleration

• Mass = Acceleration / Force

What is the formula for calculating force?

• F = m^2a

• F = ma

• F = mc^2

• F = mv

How is force related to acceleration and mass?

• Force is directly proportional to mass and inversely proportional to acceleration.

• Force is directly proportional to acceleration and inversely proportional to mass.

• Mass is directly proportional to force and inversely proportional to acceleration.

• Acceleration is directly proportional to mass and inversely proportional to force.

What is inertia?

• Inertia is the ability of an object to float in water.

• Inertia is the speed at which an object moves.

• Inertia is the force that causes objects to move.

• Inertia is the resistance of an object to changes in its state of motion.

How does mass affect inertia?

• Mass affects inertia by directly proportional relationship.

• Mass increases inertia.

• Mass has no effect on inertia.

• Mass decreases inertia.

What is the SI unit of force?

• Newton (N)

• Watt

• Joule

• Volt

What is the SI unit of mass?

• pound

• kilogram (kg)

• liter

• gram
