An object moves in a uniform circular motion at 50 m/s and takes 1.0 seconds to go a quarter circle. What is the radius of the circle? A certain centrifuge produces a centripetal acceleration of magnitude 1050 g at a point 9.50 cm from the axis of rotation. Find the number...
In uniform circular motion, are the magnitude of instantaneous velocity and the tangential speed the same thing? An airplane of mass 30000 kg travels in a horizontal loop at radius 10 m at the rate of 10000 km/h. Calculate the centripetal acceleration and centripetal force of the airplane. ...
Statement-I : When the direction of motion of a particle moving in a circular path is reversed the direction of radial acceleration still remains the same (at the given point). Statement-II : Particle revolves on circular path in any direction such as clockwise or anticlockwise the direction ...
where A is cross section area; E is modulus of elasticity; e is thickness of pipe; f is force; G is shear modulus; g is gravity acceleration; I is moment of inertia of pipe; Jp is polar moment of inertia of area; K′ is the corrected bulk modulus; m is the moment; Pf is the...
For example, a particle in circular motion at angular velocity ω and at a position r measured from a point on the rotation axis has centripetal acceleration a=ω×(ω×r). Symbolic Computation In contrast to the situation for linear algebra, where matrix operations, eigenvalue problems, and ...

The arrows indicate the direction of mean drift speed and mean drift acceleration (from n = 58 events). The arrow length was scaled down for illustration. Right, simulated streamlines. The stable regime is highlighted in red. e, Network gain heat maps. Left, 20 s cue-exposure ...
- 《Journal of Neurophysiology》 被引量: 193发表: 2002年 Vestibular Heading Discrimination and Sensitivity to Linear Acceleration in Head and World Coordinates Effective navigation and locomotion depend critically on an observer's ability to judge direction of linear self-motion, i.e., heading. The...
of rotation, and a centrifugal acceleration generated by a circular motion as well as a gravitational acceleration are taken the measured acceleration signals x and y are differentiated mathematically; and- the differentiated γ and γ, respectively, acceleration signal is differentiated one more time ...
magnitude of the net force The centripetal acceleration experienced by an object in uniform circular motion must always be pointing in which direction? a) opposing friction b) upward c) towards the center of the circle around which it is moving. d) There is no acceleration in...
