Answer:

1)  The block of wood is at rest.

2)  Weight and Normal Reaction (see attached diagram).

Explanation:

Assumptions

  • The block of wood is a particle (a body whose mass acts at a point, so its dimensions don't matter).
  • There are no other external forces involved.

Question 1

"At rest" or "resting" means that the object isn't moving.

Therefore, the block of wood is at rest.

Question 2

Forces that are acting on the block of wood:

  • Weight (W):  Due to the particle's mass, m, and the acceleration due to gravity, g:  W = mg
    (Weight always acts downwards).
  • Normal Reaction (R or N):  The reaction from a surface.
    (Normal Reaction is always at 90° to the surface).

See attached diagram.
