Projectile Motion

• projectile motion simple

  A) time to apex

  B) total time flight

  C) range to apex

  D) s

  E) h

  
• Velocity horizontal =constant

  as ideal for simple calculations, no losses
• upward movement - deceleration


  -9.81 m / s ^2
• downward movement - acceleration

  +9.81 m / s ^2
• $V_V=$$sin\theta V$


  Vertical velocity = sin angle x main velocity
• time to reach the ground from the highest point is equal to the time taken to reach that height.
• $V_H=$$cos\theta V$


  Horizontal Velocity = cos angle x velocity
• total time = time to get to max height x 2
• If given gradient use tan -1 opp / adj to get angle
