• Projectile Simulator
• Objective: 
• 6. Use the kinematics equations of Chapter Two along with the vector component method of Chapter Three to solve problems involving two dimensional motion of projectiles. 
•  
• Key PSS STRATEGY:
• Treat the motion of the oject as if it were 2 seperate objects
• 1 in free fall (y-direction)
• 2 with a constant velocity (x-direction)
• Key concepts:
• Only the y variables control time
• The y velocity at max height is 0m/s
• If symetrical
• t(up)=t(down)=t(1/2)=1/2t(total)
  
• v(up)=-v(down) 
• a=g @all points
