equations

• kinetic energy = 0.5 x mass x (speed)squared
• power = work done / time taken
• work done = force x distance moved
• momentum = mass x velocity
• elastic potential energy = 0.5 x spring constant x (extension)squared
• gravitational potential energy = mass × gravitational field strength × height
• change in thermal energy = mass × specific heat capacity × temperature change
• charge flow = current × time
• potential difference = current × resistance
• power = potential difference × current
• power = (current)2 × resistance
• energy transferred = power × time
• energy transferred = charge flow × potential difference#
• density = mass/volume
• thermal energy for a change of state = mass × specific latent heat
• weight = mass × gravitational field strength
• force = spring constant × extension
• moment of a force = force × distance (normal to direction of force)
• distance travelled = speed × time
• acceleration = change in velocity/time taken
• (final velocity)2 – (initial velocity)2 = 2 × acceleration × distance
• resultant force = mass × acceleration
• period = 1/frequency
• wave speed = frequency × wavelength
