Year 10 Physics - Acceleration

what is the velocity formula triangle

what is the speed formula triangle

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
