Distinguish between scalar and vector quantities.
Energy is a scalar quantity. State three other scalar quantities.
Fig. 1.1 shows a block at rest on a slope.
Three forces, weight W, normal contact force N and the frictional force F act on the block. The forces are in equilibrium.
[2]
The frictional force has a magnitude of 60 N.
By resolving the vector, calculate the component of the force that acts
