THE MECHANICAL UNIVERSE Name: Mai Nguyen Video 2. The Law of Falling Bodies Class: PHY2425.1p1 1. What was one of the great mysteries of physics regarding gravity? That all bodies fall with the same constant acceleration, regardless of their weight. 2. What 2 objects are dropped together in a vacuum near the beginning of the video? Penny and feather 3. Which fell faster? Same for both 4. What 2 objects were dropped simultaneously on the moon to demonstrate Galileo’s findings? Feather and a hammer 5. State Galileo’s Law of Falling Bodies: All bodies fall with the same constant acceleration, at v=gt and s=2/3 gt^2 regardless of

Unformatted text preview: their weight once the resistance from air is removed 6. According to Galileo, the distance fallen is proportional to which numbers? Odd numbers 7. The distance fallen is proportional to the of time. Square 8. Define instantaneous speed: The speed of which an object is at a certain point of time 9. Write an equation for the velocity of an object during free fall at any point: v(t)= 2ct 10. How does an object’s acceleration change during free fall? Uniformly accelerated motion. a(t)=2c it is constant. g=2c....
