... From the table opposite, it can be seen that the relative magnitude of the densities of solids and liquids are similar but the relative magnitude of gases are smaller by a factor of 1000. When a solid melts to a liquid, there is little relative change in volume due to expansion. The densities of liq ...

... Example: Head-on elastic collision of an isolated system. A softball of mass 0.200 kg that is moving with a speed 8.3 m/s collides head-on and elastically with another ball initially at rest. Afterward the incoming softball bounces backward with a speed of 3.2 m/s. a) Calculate the velocity of the ...

Physics 325 – Homework #13 due in 325 homework box by Fri, 1 pm
... Let’s approximate the Earth as a perfect sphere of radius R♁ = 6,400 km; in this approximation the g-value (acceleration due to gravity) is constant over the planet’s surface: g ≣ fgrav ≣ Fgrav / m = GM♁ / R♁2 = 10 m/s2. Of course the Earth also rotates, at an angular speed that we will label ω and ...

Determining the Drag Coefficient for a Ping Pong Ball
... Typically, the reference area A for simple shapes, such as a sphere, is exactly the same as a cross sectional area. For other objects (for instance, a rolling tube or the body of a cyclist), A may be significantly larger than the area of any cross section along any plane perpendicular to the directi ...
