PHYS 0212 One Dimensional Motion 1 One Dimensional Motion This experiment has three parts: 2. Determine g from the horizontal force due to a falling weight 1. Determine g using an inclined plane Basic Equipment: 1. Air Track Like an air hockey table but motion is only in one dimension. Virtually no friction. hose single-foot screw air track surface L 3. Determine walking speed and acceleration using distance and velocity versus time graphs PHYS 0212 One Dimensional Motion 2 2. Photogate Works like a TV or DVD remote control. The computer records the times when the gate is blocked and unblocked. 3. Picket Fence Used to measure acceleration with one photogate. x x x x x x x x PHYS 0212 One Dimensional Motion 3 Photogate The time it takes the n th slat of the picket fence to pass through the photogate will be T n . The average velocity for the n th slat will be: n n x v T = The One Photogate Method 1 average time average time nn n n vv v a + ∆− == () 1 1 1 2 n a TT + + = + 1 1 2 average time = + + The acceleration will be the change in velocity between adjacent slats. PHYS 0212 One Dimensional Motion 4 The Two Photogate Method Photogate 2 Photogate 1 The time photogate 1 is blocked.
