1C10.05 Ultrasonic Ranger
Use ultrasonic ranger and computer to measure x,v and a of a student or other moving object.
Setup Requirements: Advance preparation needed. Teacher needs to know how to use computer setup and Science Workshop / Data Studio. Software may not be on computer in classroom. May need to set up on cart before class using computer in Demo Room.
Equations: One Dimensional Motion Equations
Safety Issues: Avoid bumping into things while moving around in front of ultrasonic ranger.
1C10.10 Relative Motion Place battery powered truck on sheet, cart or large piece of paper and pull paper while truck moves in same, opposite or perpendicular direction.
Setup Requirements: Minimal Equations: V(AC) = V(AB) + V(BC) Safety Issues: Prevent vehicle from running off table. |
1C20.10 Penny and Feather Drop penny and feather simultaneously in plastic tube. Compare evacuated tube versus tube filled with air. All objects should fall with same acceleration in vacuum. Setup Requirements: Hook to vacuum pump and run about 30 sec before closing valve. Screw driver may be needed to tighten and loosen clamp. Equations: "g" same for all masses at given location. Safety Issues: Tube may break. |
1C30.10 Free Fall Timer Time ball as it drops .5m, 1m, 1.5m, etc. Setup Requirements: Stop watch needed. Equations: y = (1/2)gt2 Safety Issues: None |
1C30.15 Free Fall Timer #2 Same as 1C30.10 with different timer. Time ball as it drops .5m, 1m, 1.5m, etc. Setup Requirements: Use PASCO timer instead of stopwatch.
Equations: y=(1/2)gt2
Safety Issues: None |
