1. Projectile motion

2. Example of projectile motion # A projectile is any object upon which the only force is gravity; # Projectiles travel with a parabolic trajectory due to the influence of gravity; # There are no horizontal forces acting upon projectiles and thus no horizontal acceleration; # The horizontal velocity of a projectile is constant (a never changing in value); # There is a vertical acceleration caused by gravity; its value is 9.8 m/s 2, down.

3. Objective #1 : predict where an obstacle should be placed in order to have a projectile go through an opening of a certain height. y x 0 v 0x H X - g + + - - 0 - measure: H, h, X - calculate: d = ? t f = ? v ox = ? Particular equations General equations Use general equations again to determine particular equations and solve for d = ? h d=? tftf t

4. Objective #2 : calculate where the projectile will strike the floor when slide is at an angle - measure: , d, H - calculate: X = ?  H t tftf X=? d General equations v o = ? Particular equations v 0x v 0y v0v0  x y Determine particular equations again and solve for X = ? Record distance X also experimentally by removing the small table; compute % difference after calculations for theoretical value X.

5. Use worksheets provided to gather data for experiment Calculate distance to obstacle in experiment # 1 Calculate & measure experimentally where will the projectile strike the floor in experiment # 2

6. Good luck!
