Homework Statement
We did an experiment where A marble travels down a ramp,
rolls along for 5 cm, then falls off a desk. The marble starts off
while gravitational potencial energy, and ends with kinetic energy.
We were given a formula for the distance from the desk the marble
lands, 'x', calculated by multiplying the height of the ramp by the
height the desk and square rooting the product. So here's my question:
Why is the expected 'X' so different from the 'X' obtained in the experiment?
Homework Equations
Egpe = mgh
Eke = 1/2mv**2
The Attempt at a Solution
Is the large percent error caused by the marble
having some kinetic energy on the ramp?
HELP!
