Is measuring the acceleration of gravity using a stopwatch accurate? Why or why not? -
Answers - Not accurate. This is due to the fact that over short periods of time our
reaction times in pushing the buttons determine the precision of the measurements.
Did stopwatches exist in Galileo's time? Was there any equipment that would allow
Galileo to measure accurate results? - Answers - No. The equipment available in
Galileo's time did not allow for the accurate measurement for a free falling object.
Bc there wasn't equipment to measure the motion of a free falling object accurately,
Galileo couldn't.... - Answers - measure the short times required for objects to fall freely.
Things simply happened too fast.
How did Galileo get around this accuracy problem? - Answers - Galileo studied a motion
very similar to free fall, that of a ball starting from rest and rolling down a ramp.
As the ramp is inclined more and more, what happens to the speed of the ball? And the
time it takes for the ball to reach the end of the ramp? - Answers - Increases; decreases
When the ramp is vertical, the ball... - Answers - falls freely.
Why did Galileo choose to use a ramp to get around the problem? - Answers - He
hoped that he would be able to ignore the complications of rolling motion and friction in
order to come up with a rule for free fall before the ramp became too steep and the
ball's motion became too fast to measure
At each new ramp angle, Galileo discovered the same rule: - Answers - the acceleration
was constant. He correctly concluded that the ball would obey the same relationship if
the ramp was vertical.
Sir Isaac Newton:
*Born in England on Dec 25, 1643, the same year that Galileo died
*Raised by his grandmother
*Attended Free Grammar School
*Trinity College Cambridge
*Became interested in math, physics, and astronomy in college
*Received both a bachelors and masters degree - Answers - *While Newton was in
college, he began writing his ideas about motion in a journal. These ideas became his
three laws of motion.
*These ideas were so impressive that Queen Anne knighted him in 1705
*His foundations laid the foundations for modern science and revolutionized the world
*Died in 1727.
