Stokes'' Law

Experimental Check. We can check this result by dropping small steel balls through glycerin. We choose glycerin because it has a very high viscosity, so the balls fall slowly enough for us to be able to time them. One problem is that the viscosity of glycerin is very temperature dependent, being 1.49 Pa.sec at 20 o C, and 0.95 Pa.sec at 25 o C.

The letters HBS stand for Hardness Brinell with Steel ball, (HBW for tungsten carbide ball) but the qualification should be completed by indicating also the ball diameter (10 mm) and the applied force (load) (3000 kg). The complete and meaningful designation is therefore

EXPERIMENT 8: BALLISTIC PENDULUM

2015-6-19 · 4. Calculate the initial velocity of the steel ball v 0 = m p + m b m b v R. Express this quantity as a value plus or minus its uncertainty, thus: v0 ± v0. 5. Now remove the pendulum and fire the ball horizontally. (Find an appropriate place to shoot the ball, making sure it does not hit anyone.) Observe where the ball hits the floor. By

Physics

A feather and a steel ball are simultaneously released from rest inside the tube. What happens next? a. The steel ball falls and hits the bottom before the feather b. Both objects fall and hit the bottom at the same time c. Both objects float weightless inside the tube d. The feather falls and hits the bottom before the steel ball

Do heavier objects fall faster than lighter objects ...

This is part of a series on common misconceptions.. Is this true or false? Heavier objects fall faster than lighter objects. Why some people say it''s true: If a feather and an egg are dropped, then the egg will reach the ground first. Why some people say it''s false: Acceleration due to gravity is independent of the mass of the object.

Projectile Motion

2012-10-1 · To begin the experiment, a steel ball will be launched from a spring- loaded gun. Once the ball has cleared the barrel of the gun, the force of gravity is responsible for accelerating the ball to the ground. Frictional forces are considered negligible. With this in mind, the motion of the ball can be subdivided into two types: motion
