1.9 Identify all vector and scalar quantities in the passage below.
Ali uses 5N to pull a box 5m to the right in 3s. He then places the
box on weighing balance. The weight of the box is 10N while its
mass is 1kg.
He uses a heater to heat up the box with 50J of energy. Then, he
pulls the box again by 2m.
