Torque and Rotational Motion
A student builds a track for a toy car to go around a curve. If the student doubles the velocity of the car, what happens to the acceleration of the car if the radius is to remain unchanged?
What measuring tool would you use to find the radius of a circular spinning disc in an angular momentum experiment?
What effect would halving the radius at which an orbiting satellite moves around Earth have on its orbital speed assuming no energy is added or lost from the system?
If the mass distribution of a rotating ice skater is altered by stretching their arms outwards while spinning, how does this affect their rotational speed?

If an ice skater pulls in her arms while spinning, what happens to her rotational speed?
What happens to a rotating space station's rotation speed if its radius is halved without changing its mass distribution?

If no external torques act on a closed system, what can be said about the system's total angular momentum?
What determines the amount of torque required to change an object's state of rotation?
What impact coding practice should you follow when creating code that includes sensitive information?
