Homework Statement
Which is equal to zero if angular velocity is constant, normal or tangential acceleration?
The one with zero angular velocity is a crank. The crank moves at a fixed point.
I think it is the tangential one because that means it is a uniform motion but continuously changing speed? is that correct?
sorry it should be constant velocity. changing direction but constant speed, right?
velocity is changing. If that is changing, acceleration is also changing?
Normal acceleration is always towards the fixed point. The normal one?
Can you give a summary on how to determine which is zero among the two in different situations?
How can I determine the tangential acceleration if I have given the angular velocity?
so, if normal is zero, then tangential equals the angular acceleration. I only depend on the tangential and normal formula.
so normal is zero in a sliding block?
i mean in a mechanism, in a flat surface. the sliding block has zero normal? I'll be back.
I mean in a mechanism, the sliding block, the normal in a flat surface is zero?
its only a sample, only a schematic drawing.
its only a sketch angular velocity at 2 is constant
