Translatory Motion
Definition: Body moves straight/curved path; particles cover same distance same time; orientation unchanged.
Types: Rectilinear, curvilinear. Kinematics vs dynamics.
Equations of Motion
- ( v_f = v_i + at )
- ( S = v_i t + \frac{1}{2} at^2 )
- ( 2aS = v_f^2 – v_i^2 )
Free Fall
Under gravity ( g \approx 9.8 m/s^2 ); upward negative, downward positive.
Equations: Replace a with ±g, S with h.
Projectile Motion
Projected object under gravity.
Horizontal: constant velocity (a_x=0).
Vertical: accelerated downward (a_y=g).
Max height, time of flight, range formulas.
Momentum Conservation
Isolated system: total momentum constant.
Applications: collisions, rockets.
Collisions
Elastic: KE conserved.
Inelastic: KE not conserved.
