• Average Speed If an object travels with constant speed, then the formula for the speed of the object is given by
  

– average velocity

– Displacement

– Change in time

The fundamental Formula is:

Important Definition

Terms	Formula
Pressure	P=F/A, F is a force applied to an area, A, that is perpendicular to the force 1 Pa=1 N/m2
Work	W = Fl   W = work (Nm, J),F = applied force (N) l = length or distance moved (m)
Temperature	Fahrenheit to Celsius- ° C = 5/9 (° F – 32) Celsius to Kelvin- K = ° C + 273
Power	P = F × v F= Force,(N), V=velocity (m/s) Unit= joule/second. P= W/t W= work (J), t= Time (Seconds) 1 horsepower (hp) = 746 W
Work	W = Force * Distance P = Fv cosθ 1 J = 1 N·m
Energy	Potential energy (E)= mgh Kinetic energy(E)= 1/2 mv2 ME = mgh + 1/2 mv2 M = mass (Kg), V= velocity (m/s)
Torque	τ = r x F The unit of torque ;Newton–meter (N-m) F= Force, r= Distance
Momentum	m=mass and v=velocity Unit- kg•m/s.
Acceleration	a=Δv/Δt  Δv=change in velocity and Δt=the change in time. Unit= (m s−2)
Velocity	velocity = distance / time Unit= m/s
force	F = m ⨉ a Unit-  kg·m/s2 M= mass, a =Acceleration
Density	ρ=m/V Where, ρ=Density, m=Mass of the body, V=The volume of the body
Ohms Law Formula:	V= I × R Where, V=Voltage measured in Volts I=Electric current flowing through the conductor in amperes. R=The resistance of the material in ohms.
Frequency Formula:	f= V/λ f=Frequency of the wave, V=Velocity or wave speed ,λ=The wavelength of the wave
