Chapter 3, Problem 6A
How did Galileo discredit Aristotle’s assertion that a force is needed to keep objects, moving?
Expert Solution & Answer
To determine
The way Galileo discredit Aristotle assertion that a force is needed to keep objects moving.
Explanation of Solution
Introduction:
Aristotle predicted the idea of motion by stating two types of motion: Natural motion and volatile motion. Natural motions are not caused due to force. Volatile motions are caused due to force.
Aristotle claimed that the due to nature of the ball it comes to rest. Galileo studied the causes of motion by doing experiments like ball rolling on wooden table. In this experiment, he claimed that due to friction, ball comes to rest.
Conclusion:
Galileo by experiments discredited Aristotle assertion.

- 13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion?
