Absorption line spectrum ­ A dark line of a unique wavelength seen in a continuous spectrum

Acceleration ­ The rate of change of an object's velocity. Unit = ms-2

Ampere ­ the unit of electric current (A)

Amplitude ­ The maximum displacement of a particle from…

Displacement ­ the distance moved by an object in a particular direction (measured from a fixed
starting point)

Ductile ­ describes a material that can easily be drawn into wires (e.g. copper)

Dynamics ­ study of motion involving force and mass

Efficiency ­ the ratio of useful output energy to…

s= (u + v) t

s = vt - at2
v2 = u2 + 2as

Equilibrium ­ an object in equilibrium is either at rest or travelling with a constant velocity because
the net force on it is zero

Extension ­ the change in length of a material from its…

Kinetic energy ­ energy of an object due to its motion
Kirchhoff's first law ­ the sum of the currents entering any point (or junction) in a circuit is equal to the
sum of the currents leaving that same point. This law conveys the conservation of charge

Kirchhoff's second law…

Plastic deformation ­ the deformation of a material beyond the elastic limit

Potential difference (p.d.) ­ the energy lost per unit charge by charges passing through a
component. Unit = JC-1 or volt (V)

Potential divider ­ a circuit in which two or more components are connected in series to…

Semiconductor diode ­ and electrical component made from a semiconductor material (e.g. silicon)
that only conducts in one direction. A diode in `reverse bias' has an infinite resistance

Series ­ when components are connected end-to-end in a circuit

Speed ­ the rate of change of the distance moved by an…

Transverse waves ­ a wave in which the oscillation is at right angles to the direction in which the
wave travels

Triangle of forces ­ a closed triangle drawn for an object in equilibrium. The sides of the triangle
represent the forces in both magnitude and direction

Ultimate tensile strength…
