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.
