Galileo experimented with balls rolling on inclined planes of various angles. What is the range of accelerations from angles 0 degrees to 90 degrees (from what acceleration to what)?
Essay answers are limited to about 500 words (3800 characters maximum, including spaces).
The general formula for acceleration can be written as a = g
sin
Where g = 9.81 m/s2
For = 0, a = 0 and
for = 90 degrees, a
= 9.81 m/s2
The acceleration can be tabulated as,
a
0 0
