Acceleration, momentum, angular momentum, magnetic and electric fields Each of the examples above involves magnitude and direction.Remember: A vector is not the same as a scalar. (see Part 1 on MiLearn.com) . Scalars have magnitude only. For example, a speed of 35 km/h is a scalar ...
Some examples of vector quantities include velocity, acceleration, and force. How are the vector's direction and magnitude represented? How to Find the Magnitude of a Vector A vector is represented by an arrow. How does one find the magnitude of a vector? The magnitude or the strength of ...
Is centrifugal force the force of reaction of centripetal force? Does centripetal force equal tension? Is centripetal force negative? What direction does the acceleration vector point in uniform circular motion? How are the centripetal and tangential components of accleration produced in an object movin...

Due to the large Cherenkov angle in dense media the direction of the shower axis differs significantly from the arrival direction of the radio signal given by the Poynting vector. Furthermore, simple triangulation of the shower direction is not possible for typical detector designs because the radio...
vector determination unit (50) that, on the basis of the acceleration that is detected by the acceleration sensor (1) and the angular velocity that is detected by the angular velocity sensor (3), calculates an objective function that corresponds to at least one of the magnitude of the ...
A boy enters a patch of ice with a coefficient of friction µ with speed v. By running on the ice, the boy turns his velocity vector by 90◦ in the minimum possible time, so that his final speed is also v. What is the minimum possible time, and what kind of curve...
(the magnitude is 50 Newtons and the direction is down it is a force vector) More vector examples…. Acceleration, momentum, angular momentum, magnetic and electric fields Each of the examples above involves magnitude and direction. Remember: A vector is not the same as a scalar. (see...
If the disk is speeding up at a rate of 4 rad/s^{2}, what is the direction of the angular acceleration vector?A spinning disk is rotating at a rate of 2 rad / s in clockwise direction, what is the direction of angular speed velocity vector? If the ...
After the body leaves the ground, the only force acting on it is the force of gravity W, which produces a downward acceleration -g on the body. At the maximum height H, just before the body starts falling back to the ground, the velocity is zero. The initial velocity for this part of...
