# What you Need to know

*SPEED, DISTANCE AND TIME*Learn the SI units of distance, time and speed

Convert distance and time from one scale to another

Calculate speed, distance and time

Draw and interpret distance-time graphs

use v=d/t to calculate speed, time and distance

**MOTION FORCES**Name the four forces acting on moving objects

Describe the effect of balanced and unbalnanced forces on an object

Define "friction" and understand how it affects motion

Define "drag" and understand some basic aerodynamic principles

Describe motion, speed and acceleration

Calculate force using acceleration

*WORK AND OTHER FORCES*Explain the difference between kinetic and potential energy

Explain that force is the work done over a distance.

Describe the relationships between "mass" and "weight"

Use force=mass x gravity to calculate weight and mass.
