yeah I know the dynamics of circular motion, constant velocity or accelerated
the normal (radial) component is needed to change movement of direction and is always presented
if you want a accelerated circular movement (speeding up in a curved road) the tangential vector which produces change...
thanks for the clear and brief explanation!
must have been very confused: force which is needed to give a body certain amount of movement, is indeed the thing which control way the way the body change it's movement
more friction will slow it down down, so decceleration kicks in, but body off...
so the term (ma(t)) isn't the vector which is related to the movement of the mass?
i find that rather weird, because ma(t) equals the vector sum of all the (external) forces, so i would pressume that this net force gives the direction...
and if I do understand this correctly, I cannot predict...
hello,
new here and confused about Newton second Law.
given:
vertical mass damper system, position of the mass: x(t)=sin(t)
velocity is: v(t)=cos(t)
acceleration is: a(t)=-sin(t)
function x(t): above x-axis describes position of the mass below the vertical equilibrium point, which (below) is...
