  1. Building Newton’s Cart Use the GEARS-IDS Components to Verify Newton’s 2nd Law F = ma Who Can Engineer a Way to Obtain the Greatest Acceleration of a Given Mass from the Least Weight (Force)?

  2. Newton’s 2cd Law This GEARS-IDS apparatus will let you study Newton’s second law Mass Newton’s Cart f force= m mass a acceleration Pulley Experiment with masses and forces, and their affect on acceleration Force

  3. Exploded View of Newton’s Cart 3/16” Shaft Collar (10) Poly Cord Tire (3) 3/16” Hex Adapter (3) 3” Hex Wheel (3) ½” Shaft Collar (3) 13 Hole Angle (4) 3/16” x 4” Axle 7 Hole Angle (2) Sine Triangle (2) 6”x 9” Plate (1) 2 Students @ 20 Minutes Assembly Time

  4. Newton’s Cart Axles and bearings can be friction problems or opportunities! Engineering modifications are allowed…remember your objective is to reduce friction! Hint: Sometimes the axles don’t have to turn! Be Careful to Strap the Mass on Securely or Inertia Will Cause an Accident!

  5. Exploded View of the Pulley 7 Hole Angle (2) Sine Triangle (2) 3/16” Shaft Collar (2) 3” Hex Wheel (1) 3/16” Hex Adapter with ½” Shaft Collar (Not shown) (1) 3/16” x 4” Axle (1) 6 x 9” Flat Plate (1)

  6. Newton’s Pulley Note: Clamp the Pulley Securely to a Table

  7. Using Newton’s Apparatus 1.) Set the System Up on a High Flat Table 2.) Connect a Masons String from the Cart Through the Pulley Cart 3.) Attach a Weight (Force) to the end of the Pulley Side of the Line 4.) Place a Known Mass on the Cart 5.) Allow the Weight to Drop and Time the Speed of the Cart Over a Known Distance Pulley Note: Cart and Pulley distance = 2x Table Height. Stop the clock when the weight hits the floor

  8. Calculate the Acceleration of the Cart Note: This formula will work because the Cart started with a velocity of zero and accelerated at an (approximately) constant rate. In this particular case, the final velocity is the average velocity x 2. Where: Ca= Acceleration of the Cart in meters/sec/sec D = Distance Covered in meters T = Time in seconds

  9. Individual Experimental Data Record for Newtons Cart Activity Weight or Force in Kg or lbs. Acceleration in ms2 or fps2 Total of Mass and Cart in Kg or lbs. Trial 1.) 2.) 3.) 4.) 5.) Note: A class can elect to use either unit system, but be consistent. NEVER MIX UNITS!
