Precautions:

• Raise one end of the runway to negate friction and ensure the trolleys travel at

a constant velocity.

• Dust the runway to remove any dirt or grit.

• Use trolleys with frictionless wheels.

• Ensure there is enough ticker tape out for the trolley to use.

• Zero the balance before measuring the mass of the trolleys.

• Position the trolleys so that they will collide and move off together (Use Velcro).
