Question: Explain the velocity of two different objects: heavy rock & light feather. 1st, describe what happens when the two objects are dropped on Earth. 2nd, compare this to what happens on the Moon (make sure to refer to the movie found on the web site which shows a NASA astronaut doing this experiment on the Moon). Finally, find a cotton ball & rock that are about the same size & drop them. Then place them in two boxes with the exact same size, shape, & material. Drop them again. What do you find? Explain your findings in terms of air resistance before placing the objects in the container & after placing those in the container (i.e. try a cylindrical 35mm film holder).
Activity & description of rock & cotton ball dropped on Earth. First drop them. Then drop them in the same size container. Make sure to explain your findings in terms of the effect of air resistance.

A rifle with a barrel length of 62 cm fires a 12 g bullet with a horizontal speed of 460 m/s/s. The bullet strikes a block of wood and penetrates to a depth of 15 cm.
A beam of parallel rays from a 24 MHz citizens band radio transmitter passes between two electrically conducting (hence opaque to radio waves) buildings located 45.00 m apart. What is an angular width of the beam as it emerges from between the buildi..

A 2.00 syringe has an inner diameter of 5.00, a needle inner diameter of 0.270, and a plunger pad diameter (where you place your finger) of 1.20. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100. Suppose the ..
A diffraction grating with 395 lines/mm is 1.00 m in front of a screen. What is the wavelength of light whose first-order maxima will be 16.9 cm from the central maximum on the screen.
Two projectiles are thrown with the same initial speed, one at an angle with respect to the level ground and the other at angle 90 degree. Both projectiles strike the ground at the equivalent distance from the projection point. Are both projectiles i..
A 14 g bullet travelling at 247 m/s is fired into a 0.459 kg wooden block anchored to a 100 N/m spring. How far is a spring compressed to the nearest thousandth of meter.
At a construction site, a 63.0 bucket of concrete hangs from a light (but strong) cable that passes over a light friction-free pulley and is connected to an 83.0 box on the horizontal roof. The cable pulls horizontally on the box, and a 45.0 bag of g..
The pulley system is used to lift a 52 kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to crate. assume the masses of the chains, pulleys, and ropes are negligible, conclude the forc..
