Force Exam
Give three examples of a contact force.

 
 
 

Give two examples of a field force.
 
 

Give an example of something with a lot of inertia but little mass.
 
 

Give an example of something with a lot of inertia but a lot of mass.
 
 

Give an example of something with a little inertia and little mass.
 
 

List three forces (think in terms of vectors) acting on a racecar speeding around a track.
 
 
 
 
 
 

Describe two things (one each for the relevant terms in F = ma) you can do to hit a baseball farther with a bat.
 
 
 
 

What is the mass of a shot put that is dropped with a force of 130.5 N? (Show your work!)
 
 
 

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

Why don’t we play the game of basket ball with bowling balls? (Your answer should include the words “mass” and “force” to explain yourself in terms of physics if you expect to receive full credit for this response.)
 
 
 
 

Give an example of terminal velocity other than a parachute.
 
 

List and describe the forces in your example above.
 
 
 
 
 

Which is always stronger, static friction or kinetic friction?
 
 
 

A 15 kg block initially at rest on a horizontal floor requires 350 N of horizontal forced to set it in motion.  Once the chair is in motion, a 300 N horizontal force keeps it moving at a constant velocity. (Show your work!)
Find the coefficient of static friction between the chair and the floor.
 
 
 
 
 

Name two things (one each for the relevant terms in µs = Fs,max / Fn) you can do to keep a granite block from sliding down a ramp (Be specific).
