Hints to fix the most common mistakes in the packet:

Finding Frictional Forces:
  • Don't forget that frictional forces always oppose motion, this means that the arrow for the frictional force will go the
    opposite direction from the motion

Section Review 13.1 - p. 273
  • 1 - give the place and the cause, both!
  • 3 - remember 1 lb = 4.48 N
  • 4 - 1kg = 9.8N (on Earth)
  • 10 - Don't give me the mass (kg) give me the weight (N)

Section Review 13.2 - p. 281
  • 2 - sound travels in all directions
  • 6 - don't forget to label what each type of force is. (gravity, friction, normal, tension, compression, etc.)
  • 8 - The swing is being held up by two ropes.

Concepts - p. 258
  • 1 - this one is really tricky!!  They are not the same object.  Object 1 is on Earth and Object 2 is on the Moon, both have a
    weight of 10N.  Think about it.
  • 3 - When the food moves down the belt, what kind of friction makes it move. (this is a reference point question)
  • 7 - Just draw the vectors!
  • 11 - Don't forget to label the forces.

Problems p. 286
  • 4 - look at where the vector starts!
  • 5 - give the normal force, in newtons
