4. Uniform Circular Motion
– v = rω
– ac = rω2
Dynamics
1. Newton’s Second Law
– Fnet = ma
2. Gravitational Force
– Fg = Gm1m2 / r2
3. Tension
– T = Fnet
4. Kinetic Energy
– K = (1/2)mv2
5. Work
– W = Fd cos θ
6. Power
– P = W / t
7. Momentum
– p = mv
Rotational Motion
1. Torque
– τ = rF sin θ
2. Moment of Inertia
– I = Σmr2
3. Angular Momentum
– L = Iω
4. Rotational Kinetic Energy
– Krot = (1/2)Iω2
5. Power in Rotational Motion
– P = τω
Common Mistakes to Avoid
- Misidentifying the direction of acceleration.
- Forgetting to convert units to the correct SI system.
- Mixing up scalar and vector quantities.
