Mechanical Systems
This Achievement Standard builds on a strong understanding of Level 2 Mechanics and introduces the concepts of ;
Centre of Mass -the point in an object or system at which the force of gravity appears to act
Momentum and Vector Components -developing the Level 2 work on momentum to look at collisions in 2D
Gravity -the force of attraction between any objects that have mass
Rotational Motion -the study of rotating objects using radians as a measure of rotational displacement
Simple Harmonic Motion -motion where the acceleration is proportional to and in the opposite direction to the displacement
