Section A
Speed, Distance & Time
Speed tells you how far something travels each second. speed = distance ÷ time Rearrange it: distance = speed × time and time = distance ÷ speed. Speed is usually measured in metres per second (m/s).
Try it — set a speed and watch the distance-time graph build
Time

Distance
0 m
Speed
5 m/s
A steeper line on a distance-time graph means a faster speed. A flat line means stopped.

Section B
Forces & Motion
A force is a push or a pull, measured in newtons (N). When the forces on an object are balanced (equal and opposite) it stays still or keeps moving at a steady speed. When forces are unbalanced, the object speeds up, slows down or changes direction in the direction of the resultant force.
Try it — change the two forces and watch what the box does
Balanced — resultant 0 N. The box stays still.

Section C
Pressure
Pressure is how much force is pressing on each unit of area. pressure = force ÷ area The same force on a smaller area gives a higher pressure (a sharp knife), and on a larger area gives a lower pressure (snowshoes, camel feet). Pressure is measured in N/m² (also called pascals, Pa).
Q13
Which is the correct formula for pressure?

Q15
Why does a sharp knife cut more easily than a blunt one, even with the same pushing force?
