Instantaneous velocity describes the magnitude of velocity at any point and uses the same formula as average velocity. The difference is that it uses a near-zero change in time to minimize the effects of averaging. Another component of velocity is acceleration, which increases (or decreases) veloc...

The magnitude of the velocity and the direction of the flow in the cavity for Reynolds numbers of 100 (left) and 10,000 (right). The lid-driven cavity is a benchmark problem, so we want to compare it to existing literature (Ref. 1). To do so, let’s take a look at the velocit...
For example, in a game of billiards, the direction and magnitude of the cue ball's velocity can be represented by a vector. In navigation, vectors are used to represent the direction and speed of a moving object, such as a ship or airplane....
calculate the magnitude of the resultant of a pair of 100km/h velocity vectors that are at right angles to each other.calculate the speed of raindrops hitting your face when they fall vertically at3m/s while running horizontally at 4m/s....
Notice that the length of the bar is not needed for any calculation. Step 2: We will substitute these values into the torque equation to solve for the magnitude of the torque: $$\tau = |r|\ |F| \sin{\theta} = (0.4\ \rm{m})(20\ \rm{N})\sin{90 ^\circ} = 8.0\ \rm{...
If you were further told that the light beam has a range of 10 meters, what would be the tip of the beam's linear velocity v, its angular acceleration α and its centripetal acceleration **ac**? To solve for v, from above, v = ωr, where ω = π/...
If the velocity vector field is given as \vec{V}= (3x=2y)\vec{l}+(2z+3x^2)\vec{j}+(5t-2z^2)\vec{k}, find the magnitude of the velocity at point A (1,3,1) for time t=3 s. Find the acceleration vectors in x,y and z directions.How can...
Yes, trigonometry can be used to find the components of a vector. This can be done by multiplying the magnitude of the vector by the cosine of the angle of its direction to find the x component, and by multiplying the magnitude by the sine of the angle to find the y component. ...
How Newton's Laws apply to this situation: a mass suspended from two strings? How calculate the energy when I have force, time, and velocity given? Is a Ferris wheel an example of tension force? How to solve pendulum physics problems ...
