How can displacement be determined from an acceleration vs. time graph? What is total acceleration? What direction does the acceleration vector point in uniform circular motion? A tennis ball is thrown vertically with an initial velocity of 8 \ m/s. What will be the ball's speed when it re...
What is constant acceleration? What is total acceleration? How to find velocity with mass and momentum? What is the kinematic viscosity of air? How does velocity affect momentum? If velocity is a straight line in a graph, what is acceleration?
An electron of mass m, moves around the nucleus in a circular orbit of radius .r. under the action of centripetal force .F.. The equivalent electric current is View Solution What is centripetal acceleration ? Find its magniude and direction in case of a uniform circualar motion of an obje...
This rotational force is also used to simulate the acceleration of a space launch for astronaut training. When a rocket is first launched, it is so laden with fuel and oxidizer that it can barely move. However, as it ascends, it burns fuel at a tremendous rate, continuously losing mass.Ne...
(The Greek letter alpha), is often zero in basic rotational motion problems because **ω** is usually held constant. But because **vt**, as noted above, is always changing, there exists a **centripetal acceleration ac** directed inward toward the rotation axis and ...
As it is shown in the first part of this short essay, duality plus conservation laws allow the violation of Bell’s inequalities for any spatio-temporal separation. To dig deeper into particle dualism, in the second part, a class of models is proposed as a working framework. It encompasses...
scales, leading to the remarkable conclusion that the expansion of the universe is in fact accelerating over time, which in the Lambda-CDM model corresponds to a positive cosmological constant, though there are more complex “dark energy” models that are also proposed to explain this acceleration...
Step-by-Step Solution1. Definition of Centripetal Force: Centripetal force is defined as the force that acts on an object moving in a circular path. This force is always directed towards the center of the c
A train engine of mass m is chugging its way around a circular curve of radius R at a constant speed v. Draw a free body/force diagram for the train engine showing all of the forces acting on it. Evaluate the total vector force acting on the engine as a function of its speed ...
it's just the the negative of the product of the mass of the object and the acceleration of the frame. using the acceleration of an object moving in a circle, i can write this force equation (in just the vertical direction): however, there is something significantly different about a ...
