Previous Next Howitzer on an Incline # 1D60.15
Description: This demonstration shows the independance of hozizontal motion (the cart) and vertical motion (the ball's path) of a single system in a slightly different way than 1D60.10 Instructions: The Howitzer is attached to a Dynamics Cart. The track is inclined. The ball is shot perpendicular to the track when the cart passes a photogate trigger. The ball will not land back in the cart. Have your student predict where it will land. Hazards: Keep an eye on the ball, as it will not land back in the howitzer ball-catch. Parts: PASCO Howitzer attached to a cart PASCO dynamics cart track Block to lift the track PASCO ball Purchased/Built: purchased Quant. in Demo Room: 1 Source: Pasco Scientific Demo References The American Journal of Physics AJP 44(8),783 Some strobe pictures and drawings show the ball is always above the cart relative to the incline, but not always above the cart relative to the horizontal. The American Journal of Physics AJP 43(8),732 Short note on inclined ballistic cart systems. The American Journal of Physics AJP 42(4),326 Perform the howitzer and tunnel on an incline with the car starting at rest.
