Which of these quantities is a scalar?

• A displacement
• B force
• C distance
• D velocity

Which of these is a correct unit for pressure?

• A $N/m$
• B ${N/m}^2$
• C $N\; m$
• D ${N\; m}^2$

A wooden block is at rest on a horizontal table.

Draw on this

Why is the wooden block at rest?

• A only gravity acts on the block
• B the upward vertical force is greater than the downward force
• C there is no resultant force acting on the block
• D no forces act on the block

The mass of the wooden block is $250g$. State the equation linking weight, mass, and gravitational field strength, $g$.

Calculate the weight of the wooden block.
