Topics include atomic and nuclear physics, electricity and magnetism, heat transfer, geophysics, light and the electromagnetic spectrum, earth, forces, radioactivity, particle physics, space, waves, sound and medical physics
HT = Higher Tier only equations. kinetic energy = 0.5 × mass × (speed)2. k 2. elastic potential energy = 0.5 × spring constant × (extension)2. e k e2. 2. gravitational potential energy = mass × gravitational field strength × height. p = m g h. change in thermal energy = mass × specific heat capacity × temperature change.
Kinematic equations relate the variables of motion to one another. Each equation contains four variables. The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi).
