Here’s a concise, objective review based on common feedback from teachers, students, and parents:

  • Solution: $PE = m \cdot g \cdot h \rightarrow PE = 2 \cdot 10 \cdot 3 = 60 , J$.

2. Dynamics (Newton’s Laws)

  • Newton's 2nd Law: $F = m \times a$ (Force = Mass $\times$ Acceleration).
  • Gravity: $F_g = m \times g$ (Remember, $g \approx 9.8 , m/s^2$ or $10 , m/s^2$ depending on your teacher's rule).
  • Friction: Know the difference between static friction and kinetic friction.
