✨ Key Takeaways

• KinematicsUnderstand the difference between speed (scalar) and velocity (vector). Key formulas include:

  • ( D = VT ) (displacement = velocity × time)
  • ( Vf = Vi + at ) (final velocity = initial velocity + acceleration × time)
  • Projectile motion formulas for maximum height and range.

• Forces

  • Newton's laws describe the relationship between motion and forces.
  • Friction is calculated using coefficients of kinetic and static friction.

• Uniform Circular Motion

  • Centripetal acceleration ( ac = \frac{V^2}{R} ) and centripetal force ( Fc = m a_c ).

• Work, Energy, and Power

  • Work done is ( W = F \cdot d ) (force × displacement).
  • Kinetic energy ( KE = \frac{1}{2} mv^2 ) and potential energy ( PE = mgh ).
  • Power is the rate of doing work ( P = \frac{W}{t} ).

• Momentum and Impulse

  • Momentum ( p = mv ) and impulse ( J = F \Delta t ).
  • Impulse-momentum theorem: ( \Delta p = J ).

• Rotational Motion

  • Angular quantities relate to linear quantities through radius.
  • Torque ( \tau = r \times F ).

• Gravitation

  • Gravitational force ( F = \frac{G m1 m2}{r^2} ) and gravitational potential energy ( PE = -\frac{G m1 m2}{r} ).

• Simple Harmonic Motion

  • Period of a mass-spring system ( T = 2\pi \sqrt{\frac{m}{k}} ) and for a pendulum ( T = 2\pi \sqrt{\frac{L}{g}} ).
