What is the word equation for velocity
velocity = distance / time
What is the symbol equation for velocity
v = s/t
What is the word equation for weight
Weight = mass x gravitational field strength
What is the symbol equation for weight
W = mg (note that “w” must be uppercase)
What is the word equation for inertial mass (Newtons 1st Law)
inertial mass = force / acceleration
What is the symbol equation for inertial mass
m = f/a
What is the word equation for resultant force (Newton’s 2nd law)
Resultant force = mass x inertial mass
What is the symbol equation for resultant force?
f = am
What is the word equation for uniform acceleration (you are not given the time)
final velocity squared - initial velocity squared = 2 x acceleration x distance
What is the symbol equation for uniform acceleration (you are not given the time)
v2 - u2 = 2as
What is the word equation for acceleration (you are
given the time)
acceleration = change in velocity/ time
What is the symbol equation for acceleration (you are
given the time)
a = v - u / t
What is the word equation for momentum
momentum = mass x velocity
What is the symbol equation for momentum
p = mv
What is the unit for momentum
Kgm/s
What is the unit for acceleration
m/s^2
What is the unit for mass
Newtons (N)
What is Newton’s first law
An object at rest will stay at rest and an object in motion will stay in uniform motion unless acted upon by an unbalanced force
What is Newton’s second law
Resultant force = mass x acceleration
What is the word equation for change in momentum?
Change of momentum = Resultant force x time for which the force acts
What is the symbol equation for change in momentum
(delta) p = f / t
