Chapter 5 Work and Energy conclusion
... A ball is thrown upward with an initial speed v from the roof of a building. An identical ball is thrown downward with the same initial speed v. When the balls reach the ground, how do the kinetic energies of the two balls compare? Ignore air resistance effects. a) The kinetic energies of the two ba ...

... This is because atmospheric pressure acts in all directions, and its effect cancels out in every direction. This means we can also ignore the pressure forces at outlet sections where the fluid is discharged to the atmosphere since the discharge pressure in such cases is very near atmospheric pressur ...

Simple Harmonic Motion – Concepts
... Have you ever wondered why a grandfather clock keeps accurate time? The motion of the pendulum is a particular kind of repetitive or periodic motion called simple harmonic motion, or SHM.1 The position of the oscillating object varies sinusoidally with time. Many objects oscillate back and forth. Th ...

... 6.7 Falling and Air Resistance At low speeds, air resistance is often negligible, but at high speeds, it can make quite a difference. If you hold a baseball and tennis ball at arm’s length and release them at the same time, you’ll see them strike the floor at the same time. But if you drop them from ...
