Angular acceleration is change in angular velocity over time.
α=(16-4)/3 = 4 rad/s².

K=½mv².
K=½×2×100 = 100 J.

Linear speed is v=rω.
V=0.5×8 = 4 m/s.

Potential energy change is mgh.
5×10×8 = 400 J.

Rotational dynamics gives τ=Iα.
τ=3×4 = 12 N·m.

Power is work divided by time.
P=600/3 = 200 W.

Opposing torques subtract.
The net magnitude is 15-9 = 6 N·m.

Energy transferred is Pt.
1000×20 = 20,000 J.

Density measures how much mass is contained in a given volume.
Its SI unit is kg/m³.

Net work equals the change in kinetic energy.
Kf=20+80 = 100 J.

Pressure describes how force is distributed over a surface.
Its SI unit is the pascal.

ΔK=½m(v²-u²).
With m=2, ΔK=49-9 = 40 J.
