- Velocity =is the rate of change of displacement(s) =s/t it’s SI units is Metre per second (m/s)
- Acceleration - is the rate of change of velocity (v) it's SI units is Metre per second square =v-u/t g=9.8 or 10approx
- Force-is the product of mass and it's Acceleration(a) =ma it's SI units is Newton(N)
- Momentum - is the product of mass and it's velocity =mv it's SI units is Newton second
- Work(w) - is the product of force and it's distance Fxs it's SI units is joule(J) 1 Newton x 1 meter =1J
- Potential energy is the energy due to level or position
*kinetic energy is the energy due to motion HEAT CAPACITY (C) is the heat required to raise temperature of substance by 1 °C =mc and it's SI units is J/K or J/°C,( 1K=1°C)
SPECIFIC HEAT CAPACITY heat required to raise temperature of unit mass of substance by 1°C (=C/m) it's SI units is J/kgK or J/gK for water c=4200J/kgK or 4.2J/gK
SPECIFIC LATENT HEAT is the heat required to change unit mass from solid to liquid or from liquid to vapour without temperature change (it's SI units is J/kg or J/g
LINEAR EXPANSIVITY is the increase in length per unit length per °C temperature rise (it's SI units is per K or per °C
CUBIC EXPANSIVITY increase in volume per unit volume per °C temperature rise (it's SI units is per K or per °C
VOLUME COEFFICIENT OF GAS increase in volume per unit volume at 0°C per °C temperature rise,pressure being constant (it's SI units is per K or per °C) volume expansivity of most gases is approximated as 1/273
PRESSURE COEFFICIENT OF GAS is the increase in pressure per unit pressure at 0°C per °C temperature rise, volume being constant (it's SI units is per K or per °C) the pressure coefficient of gas is approximated as 1/273 for most gases
ABSOLUTE TEMPERATURE(T) Is the temperature measured from absolute zero (T=273+t°C) it's SI units is K (0K=absolute zero, 273K=0°C) Physics
