Projectiles

Projectile:

• What defines it?
• Vocabulary:
• trajectory
• hang time
• range
• launch angle
• launch velocity
  
• Print out the Questions below
• Projectile Questions 
• 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

OBJECTIVES:

After studying the material of this chapter, you should be able to: 
1. Represent the magnitude and direction of a vector using a protractor and ruler. 
2. Multiply or divide a vector quantity by a scalar quantity. 
3. Use the methods of graphical analysis to determine the magnitude and direction of the vector resultant in problems involving vector addition or subtraction of two or more vector quantities. The graphical methods to be used are the parallelogram method and the tip to tail method. 
4. Use the trigonometric component method to resolve a vector components in the x and y directions. 
5. Use the trigonometric component method to determine the vector resultant in problems involving vector addition or subtraction of two or more vector quantities. 
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.

Question: what are some sources of error in the lab? 
How much error do they introduce?  

How could you correct for the errors?

Speed of sound = 345m/s
