What is the formula for force
F= MA (force= mass x acceleration)
What is the formula for work done
W= F x D (work done= force x distance moved by force)
What is the formula for average speed
V= D/T (velocity=distance/time)
What is the formula for weight
W=MG (weight= mass x gravitational field strength)
What is the formula for momentum
P=MV (momentum= mass x velocity)
What is the formula for orbital speed
V= 2 x pi x r/t (2 x pi x orbital radius/time)
What is the formula for moment
Moment=FD (moment= force x perpendicular distance between force and pivot)
What is the formula for power
P=W/T (power = work done/time)
What is the formula for change in gravitational potential energy
GPE= mgh (Gravitational potential energy= weight x change in height)
What is the formula for kinetic energy
KE=1/2 x mv squared (Kinetic energy= mass x velocity squared)
What is the formula for efficiency
Efficiency= useful energy transferred/ total energy supplied
What is the formula for charge
Q=IT (Charge= current x time)
What is the formula for voltage
V=IR (voltage= current x resistance)
What is the formula for power
P=VI (power= volts x current)
What is the formula for electrical energy
E=I x T x V (electrical energy= current x time x voltage)
What is the formula for wave velocity
Wave velocity= frequency x wavelength
What is the formula for frequency
Hz=1/t (frequency=1/time)
What is the formula for density
P=m/v (density= mass/volume)
What is the formula for pressure
P=F/A (pressure=force/ area)
What is the formula for pressure in a liquid
P= p x h x g (pressure in a liquid= density of liquid x height of liquid x gravity)
