Question 1.
What is the definition of non-uniform angular motion?
Show hintHide hint
Think about whether the speed is constant or not.
Question 2.
Give one example of non-uniform angular motion.
Show hintHide hint
Consider objects that change speed while rotating.
3Question 3.
What indicates non-uniform angular motion?
- Constant angular velocity
- Changing angular velocity
- Zero angular velocity
Show hintHide hint
Consider what happens when speed varies.
4Question 4.
True or False: Angular acceleration is present in non-uniform angular motion.
- True
- False
Show hintHide hint
Think about what happens to speed.
Question 5.
A wheel of a bicycle accelerates from 10 rad/s to 25 rad/s over 4 seconds. Calculate the angular acceleration.
Show hintHide hint
Remember the formula for finding angular acceleration.
Question 6.
A merry-go-round decelerates from 12 rad/s to a complete stop in 6 seconds. What is the angular acceleration?
Show hintHide hint
Note that deceleration means acceleration will be negative.
