Hooke’s Law
As long as the elastic limit of the body is not exceeded, the strain produced is proportional to the stress causing it.
Moment of Force
The product of the force and the perpendicular distance from the line of a action of the force to the pivot.
Sensitivity of the thermometer
Large change in reading/length for small change in temperature.
Linearity
Distance between each degree on scale is the same.
Range of thermometer
Highest and lowest temperature that the thermometer can measure.
Heat capacity
The amount of energy required to raise the temperature of the body by 1K or 1 degree Celsius.
Specific heat capacity
The amount of energy required to raise the temperature of a unit mass of the material by 1K or 1 degree Celsius.
Specific latent heat of fusion (Lf)
The amount of energy needed to change a unit mass of the substance from solid to liquid without a change in temperature.
Specific latent heat of vaporization (Lv)
The amount of energy needed to change a unit mass of the substance from liquid to gas without a change in temperature.
Wavefront
The line that join all identical points on a wave.
Transverse wave
Waves which travel in a direction perpendicular to the direction of the vibrations.
Longitudinal wave
Waves which travel in a direction parallel to the direction of the vibrations.
Ciritcal angle
The angle of incidence in the optically denser medium for which the angle of refraction in optically less dense medium is 90 degree.
Conditions required for total internal reflection
i)The light ray must travel from an optically denser medium towards an optically less dense medium.
ii)The angle of incidence must be greater than the critical angle. i>ic
Electromotive force (emf)
The work done by the source in driving a unit charge around a complete circuit.
Potential difference
The work done to drive a unit charge through the component.
Function of diode
Allows current to flow one direction only.
Function of commutator
The commutator changes the direction of the current through the coil, so the force change the direction and keep the coil turning.
Electromagnetic Induction
The process in which emf is induced in the close circuit due to change in magnetic field.
Why does transformer require AC?
Alternating current can occur the changing magnetic field in the primary coil which induced a curren/emf in the secondary coil.
Analogue
Readings can vary smoothly and have any value between the lowest and highest.
Digital
Readings can only have certain definite value, usually just on or off.
Half-life
The time taken for half the number of atoms in any sample of a radioactive element to decay.
