... Question Where would the ball land if the van was slowing down? Answer It would land forward of the release point because the ball continues moving with the horizontal velocity it had when released, whereas the van is slowing down. As before, the descriptions of the ball's motion are different. But ...

Because the electrons in the balloon are closer to the attractive positive charges in the sphere, and farther away from the repelling negative charges, there is a net f ...

Sitting in a chair connected to a rope that passes over a frictionless pulley (Fig. P5.51), Pat pulls on the loose end of the rope with such a force that the spring scale reads 250 N. Pat's true weight is 320 N, and the chair weighs 160 N. (a) D ...

However, it is simpler than all of that and right in front of us. The Sun and the solar wind are the most powerful fo ...

Notes on Fluid Dynamics These notes are meant for my PHY132
... In this introductory class, we will limit our treatment to moving fluids whose density doesn’t change and ones that are at steady state. There are two main relationships that we will derive and apply. The first one is called the ”continuity equation”, and the second one Bernouli’s equation. By stead ...

The ends of the rope are at the same height and they make an angle θ with the trees. a) What is the tension at the ends of the rope where it is connected to the trees? b) What is the tension in the rope at a point midway between the trees? Be sure you show any free body force diag ...

Artificial gravity
Artificial gravity is the theoretical increase or decrease of apparent gravity (g-force) by artificial means, particularly in space, but also on Earth. It can be practically achieved by the use of different forces, particularly the centripetal force and linear acceleration.The creation of artificial gravity is considered desirable for long-term space travel or habitation, for ease of mobility, for in-space fluid management, and to avoid the adverse long-term health effects of weightlessness.A number of methods for generating artificial gravity have been proposed, as well as an even larger number of science fiction approaches using both real and fictitious forces. Practical outer space applications of artificial gravity for humans have not yet been built and flown, principally due to the large size of the spacecraft required to produce centripetal acceleration.
