Question
May I please get help with that question... a and b in both. Its tricky reasoning questions so more details would help.. thanks A body moves in a circle with constant angular velocity. (a) Does it have a non-zero tangential acceleration? Is its magnitude constant? Is its direction constant? (b) Does it have a non-zero radial acceleration? Is its magnitude constant? Is its direction constant? A body moves in a circle with constant angular acceleration. (a) Does it have a non tangential acceleration? Is its magnitude constant? Is its direction constant? (b) Does it have a non-zero radial acceleration? Is its magnitude constant? Is its direction constant?Explanation / Answer
Here ,
a)
for a body moving with constant angular velocity
the angular acceleration will be zero that means tangential acceleraetion is zero.
tangential acceleraetion = angular acceleration * radius
hence , the tanegential acceleration is Zero.
b) as the radial acceleration is given as
radial acceleration = w^2 * r
w is the angular speed
hence , the radial acceleration is non zero.
it's magnitude is constant. the direction keeps changing

a)
the angular acceleration is non zero that means tangential acceleraetion is non zero
tangential acceleraetion = angular acceleration * radius
hence , the tanegential acceleration is non zero.
the magnitude is constant.
the direction keeps changing
b) as the radial acceleration is given as

w is the angular speed
hence , the radial acceleration is non zero.
it's magnitude is changing as the angular velocity is changing. the direction keeps changing
