Question

A vertical force F acts on a block of wood of weight mg, as shown in the figure below. All other forces, if present are negligible. Patrick argues that since the forces are balanced, the block is at rest. Joanne disagrees and says the block is in uniform motion. Who is correct? Explain your answer.

Answer 1

when an object is at rest only the normal force (the top arrow) and gravity (bottom arrow) is present. it is difficult to say from a free body diagram with limited information that an object is in uniform motion

Answer 2

So the best option will be at rest?

Answer 3

yuppp!

Answer 4
