Learning Goals
At the end of the module students should be able to:
Motion

define the terms
 speed
 velocity
 displacement
 acceleration

plot and interpret distancetime graphs from results obtained from experiments

plot and interpret various graphs representing and involving motion e.g. distance versus
angel of slope

calculate the distance traveled at constant speed using, distace = speed x time

calculate speed from experimental observations of distance and time

plot and interpret speedtime graphs using results obtained experimentally

calculate acceleration using the formula, acceleration = (new speed  old speed) / time
Machines

explain the term gear ratio

perform experiments to show how gear ratio affects speed

describe qualitatively how the weight that can be lifted is affected by gear ratio

describe qualitatively how the speed at which a mass is lifted is affected by gear ratio

plot and interpret graphs of speed at which mass is lifted versus the gear ratio
Forces

describe what a force does to a body i.e. causes
 change of shape
 change of direction
 change of speed

graph the relation between forces and power level for a Lego robot
