Mechanics Quiz

1   . What  is  the mass    of  a   block   with    weight  100 N?

2   . Give  the equations   for two types   of  potential   energy, identifying each.

3   . When  an  object  of  mass    m is    on  an  incline of  angle   θ   ,   one must    break   the weight  of  an  object  into

components  parallel    and perpendicular   to  the incline.

        i.  What    is  the component   of  the weight  parallel    to  the incline?_________

ii. What    is  the component   of  the weight  perpendicular   to  the incline?_________

4   . Write two expressions for work,   including   the definition  of  work    and the work-energy principle.

5   . Quickly   identify    as  a   vector  or  a   scalar:

6   . Name  at  least   four    things  that    can NEVER   go  on  a   free-body   diagram.
