Record the values observed or provided in the video and do the calculations. When two fields are provided for a quantity, the number part of the answer goes into the first
field and the units in the second field. Example:

When converting units, never round any numbers. Example: 1.23 cm = 0.0123 m, not 0.01 m or 0.012 m.
There are 1000 g in 1 kg and 100 cm in 1 meter.
Convert Mass of ball bearing to
kg.

When doing calculations below, always use the quantity in standard metric units (
kg
for mass, meters
for distance).
Calculate the Gravitational Potential Energy for each trial. Remember that weight (
W
) and mass (
m
) are not the same thing in physics. Do not round these values.

The three values for the spring constant should be similar although not exactly the same. Round your answers off to 1 digit after the decimal point. Make sure you give the correct units with all your numbers.
All fields initially shaded yellow require a number or a unit. Make sure you have provided all answers.
