In Which Situation Listed Would Angular Acceleration Be Positive. This means that the scale is pushing up on the person with a force greater than his weight, as it must in order to accelerate him upward. Clearly, the greater the acceleration of the elevator, the greater the scale reading, consistent with what you feel in rapidly accelerating versus slowly accelerating elevators. During which interval or intervals is the train’s acceleration positive? (a) when the torque of a force causes counterclockwise rotation about the axis of rotation, we say that its sense is positive, which means the torque vector is parallel to the axis of rotation.

The angular velocity of the object to change a net torque applied to an object causes __________. In which situation listed would angular acceleration be positive? İ/ an object is rotating clockwise and speeding up submit request. Since up is positive, and the rock is thrown upward, the initial velocity must be positive too.
This gives ω = ω0+αt (8.7) we followed very similar steps in finding the equation v = v0+at in one.
(if we do this, the acceleration will be positive for each mass. Arc length s centripetal acceleration ac w = work energy theorem: The tourque is the product of force and distance (in this case, the radius): We use plus and minus signs to indicate direction, with up being positive and down negative. I not sure the direction of angular speed as it is not stated in my notes. Now let’s do a similar analysis to determine acceleration.
