A force is a push or a pull upon an object that may cause the object to change velocity. Forces are vectors, meaning that they have both magnitude and direction. If a person pushes a box with a force of 10 N towards the right, the magnitude is 10 N and the codirection is to the...

Resultant Gamma after Einstein velocity addition Hello. Let's say that I am in a frame in which I see a rocket traveling at v. This rocket then fires a projectile forward with velocity u in its rest frame. I can find u' easily enough using the Einstein velocity addition formula. However...
Assertion : For a free falling object, the next external force is just the weight of the object . Reason : In this case the downward acceleration of the object is equal to the acceleration due to gravity. View Solution The following shows the time-velocity graph for a moving object. The ...
Excess water is removed from the apertured film by the impingement of high velocity air from knives 52 and by suction through the suction slots in drums 51. Air knives 52 operate at an air temperature range between about 60°-82°C (150°-180° F). Total air flow through the twelve ...

Mention the correct formula. What is the relationship between velocity, acceleration, mass and force? A 7.50 kg object has the given x and y acceleration components. a_x=(0.47 m/s^2) + (0.75 m/s^2) t, a_y=(11.5 m/s^2)-(0.67 m/s^2) t What is the magnitude F_{n...
As is well known (Usachev, 1915; Zorev, 1966; Shaw, 2004), power is calculated as the product of the resultant force and the velocity in the direction of this force. In metal cutting, however, the magnitudes of the force components and the corresponding velocities have to be considered....
In an accelerate motion of a point upon a circle its tangential velocity changes continuosly; it is no more the value of the initial istant. So the correct formula to use is (v, v0 and a are tangential): v-v0 = at t=0.191 s a = 0.361 m/s^2 v0=0.270 x 0.400 = 0.108 m...
To find the maximum resultant force when two forces of 12 N and 8 N act on a body, we can use the formula for the resultant of two vectors. The maximum resultant occurs when the two forces are acting in the same direction.1. Identify th
