Newton's First Law Intro

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

The tendency of an object to resist a change in its motion

• acceleration
• inertia
• mass
• frame of reference

What kind(s) of objects have inertia?

• all objects with mass
• only objects at rest
• only objects in motion
• only objects whose motion is being changed

If one object has twice as much mass as another object, it also has twice as much...

• inertia
• velocity
• acceleration due to gravity
• DO NOT PUSH ME

The law of inertia (Newton’s First Law) applies

• to both moving and nonmoving objects
• only to moving objects
• only to objects that are not moving

Why does an 18-wheeler truck have more inertia than a bicycle?

• it has more mass

• it has more volume

• it is not as aerodynamic

• It has more space

Objects with greater _________ also have greater inertia.

• speed
• mass
• temperature
• friction

You push on a car and it does not move.  What is true about the inertia?

• The inertia is changing
• The inertia of the car is too great 
• The inertia of the person is equal to the car
• There is not inertia because of no movement

Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a _________acts on them.  

• force
• velocity
• inertia
• acceleration
