What is the formula for pressure?
Pressure = Force / area
Pressure = Mass / volume
Pressure = Work / time
Pressure = Energy / distance
What is the formula for resultant force?
resultant force = mass x acceleration
resultant force = mass + acceleration
resultant force = mass / acceleration
resultant force = mass - acceleration
How to calculate frequency, f?
f = v / λ
f = λ / v
f = v * λ
f = v + λ
What is the relationship between period (T) and frequency (f)?
T = 1/f
T = f
T = 2f
T = f^2
What does it mean by "background radiation"?
nuclear radiation in an environment where no radioactive source has been deliberately introduced
radiation emitted from the sun
radiation produced by man-made devices
radiation that occurs only during a nuclear event
What is the formula for gravitational potential energy (GPE)?
GPE = mv^2
GPE = mgh
GPE = 1/2 mv^2
GPE = mg^2
O-Level: How to calculate refractive index, n?
n = @@\frac{\sin\ i}{\sin\ r}@@
n = @@\frac{c}{v}@@ (@@\frac{speed\ of\ light\ in\ vacuum}{speed\ of\ light\ in\ medium}@@)

SI Unit for voltage or potential difference
A
V
W
A/m
How to calculate electric current, I?
I = Q * t
I = Q / t
I = Q + t
I = Q - t
State the Principle of Conservation of Energy.
Energy can be created and destroyed.
Energy can be transferred but not transformed.
Energy cannot be created nor destroyed, it may be transferred from one store to another.
The total energy in an isolated system can vary.
Work done = power x ...............
time
energy
force
distance
SI Unit for density
kg / m3
g / cm3
lb / ft3
kg / L
How to calculate potential difference, V?
V = W / Q
V = Q / W
V = W * Q
V = W + Q
What is the formula for acceleration?
acceleration = mass / resultant force
acceleration = velocity / time
acceleration = resultant force / mass
acceleration = force x mass
wave speed, v = ...........
f λ
f / λ
λ / f
f + λ
What is the formula for acceleration?
acceleration = (v - u) / t
acceleration = v + u
acceleration = u / t
acceleration = (v + u) / 2
What is the formula for kinetic energy (KE)?
KE = ½ m v
KE = m v²
KE = ½ m v²
KE = m v/2
SI Unit for charge
C
A
V
J
What is the formula for velocity?
velocity = change in displacement / time
velocity = distance / time
velocity = acceleration x time
velocity = force / mass
