1. What did Aristotle believe about the relative speeds of fall for heavy and light objects?
Expert Solution & Answer
To determine
Aristotle’sconcept about the relative fall for heavy and light objects.
Answer to Problem 1RCQ
Aristotle believed heavy objects should travel faster than lighter objects.
Explanation of Solution
Aristotle’s put forward the idea about fall of bodies from daily life experiences, not on scientifically planned experiments.
Natural motion occurs as result of natural forces. Violent motion is produced by applying a force. Aristotle put forward two main assertions about the motion.
According to Aristotle, heavy objects must reach ground first than lighter objects when they are put together from a height. Aristotle also believed that force should provide continuously to keep motion and object stops when the pull is removed, thus, Aristotle argued that moving object stops when force vanishes.
Later from Galileo’s experiments, Aristotle’s ideas became irreverent.
Conclusion: Aristotle believed heavy objects should travel faster than lighter objects.

2. DETERMINING GRAVITATIONAL ACCELERATION: In this step, we will determine Earth's
gravitational acceleration using free-fall data. We also wish to gain some appreciation for
why measuring gravitational acceleration is difficult.
2.1. One way to measure gravitational acceleration is to simply drop an object and measure
its time of flight, i.e. the time it is in air before landing. Suppose you drop an object from
height h = 2 m. To minimize the effect of drag (air resistance), suppose the object is
aerodynamic in shape, and has a small cross-sectional area but a large mass. Under
these conditions, drag will be negligible. You will measure the time of flight using a
stopwatch.
2.1.1. Suppose you measure the time of flight to be 0.639 s.
