# 3.1 Measurements and their errors

Content in this section is a continuing study for a student of physics. A working knowledge of the specified fundamental (base) units of measurement is vital. Likewise, practical work in the subject needs to be underpinned by an awareness of the nature of measurement errors and of their numerical treatment. The ability to carry through reasonable estimations is a skill that is required throughout the course and beyond.

# 3.5 Electricity

3.5 Electricity 3.5.1 Current Electricity 3.5.1.1 Basics of Electricity Content Electric current as the rate of flow of charge; potential difference as the work done per unit charge. I = Q/t, V = W/Q Resistance defined as R = V/I. Opportunities for Skills Development Students can construct circuits from the range of components. Electric current … Continue reading 3.5 Electricity

# 3.6 Further mechanics and thermal physics

3.6.1 Periodic motion 3.6.1.1 Circular motion Content Motion in a circular path at constant speed implies there is an acceleration and requires a centripetal force. Magnitude of angular speed, ω = v/r Radian as a measure of angle. Direction of angular velocity will not be considered. Centripetal acceleration, a = v2/r = ω2r. The derivation of the … Continue reading 3.6 Further mechanics and thermal physics
