what is the velocity formula triangle
what is the speed formula triangle
when does an object accelerate
when an unbalanced force acts upon it to change it's motion
what is positive acceleration
when an object speeds up
what is negative acceleration
when an object slows down
what is zero acceleration
constant speed
what is acceleration
a measure of that rate at which an object changes it's velocity
if an object mainatins the same speed but changes direction does it accelerate
yes because acceleration is a vector quantity
what are the standard units for acceleration
m/s/s or ms^-2
acceleration formula
a = (v-u)/t
initial velocity formula
u=v-at
final velocity formula
v = u+at
displacement from acceleration formula
s = ut + 1/2at^2
what does each letter mean in acceleration formulas
a = acceleration, t = time, v = final velocity, u = initial velocity and s = displacement
