Work
Explanation:
Energy can do work or bring about change.
Energy is simply the ability to do work. When work is done, changes occur in a body.
- There are different forms of energy and they are all related to work done.
- When work is done on a body, a force causes a change in that body.
- Both potential and kinetic energy are the same as work done.
- Energy is needed to do work.
- Work is done when a body changes energy.

Answer:
-5.9 rad/s^{2}
Explanation:
radius (r) = 30 cm = 0.3 m
mass (m) = 1.05 kg
initial speed (u) = 77 rpm
final speed (v) = 0 rpm
time (t) = 1.37 s
angular acceleration =
therefore
initial speed (U) = 77 rpm = 77 x (2π/60) = 8.06 rad/s
final speed (v) = 0 rpm = 0 rad/s
angular acceleration = 
= -5.9 rad/s^{2}
Explanation:
Power = Work done ÷ Time
