Newtons & Force #2: Newton’s 1st Law of Motion
State Newton’s First Law of Motion.

 
 
 

Restate Newton’s First Law of Motion in your own words.
 
 

Give three examples of something at rest.
 
 
 
 

Give three examples of something in motion at a constant speed in a straight line.
 
 
 
 

Give three examples of something in motion experiencing a net external force.
 
 
 
 

Define:

inertia
 

net external force (aka resultant force)
 

equilibrium
 
 
 
 
 

How is inertia related to mass?
 
 
 
 

If the net external force on an object is zero, does hat mean that no force is acting on it? Explain.
 
 
 
 

If the net external force equals zero, what is known about the velocity of the object?
