Before beginning a discussion on how to calculate velocity, it is first necessary to clear the common confusion that young physics students typically have about speed and velocity. Speed is a scalar quantity, which means it only has a magnitude and no direction. On the other hand, velocity is...
You can use these same formulas to calculate a projectile's initial velocity if you know the height it reaches when tossed into the air and the number of seconds that it takes to reach that height. Simply plug those known values into the equations and solve for v0instead of h. References...
Add this velocity to the initial velocity. In the example above, if the object had an initial velocity of 5 meters per second, the resultant velocity would be 34.4 meters per second. The overall formula here is v (final) – at + v (initial) where "v" is velocity, "a" is acceleratio...

Step 2:Use the formula {eq}v_{x} = v (cos\theta) {/eq} for x-component (horizontal) and {eq}v_{y} = v (sin\theta) {/eq} for y-component (vertical) of the velocity. To calculate the x- and y- components of the velocity, we use the respective formulas: ...
Calculating superficial velocity is relatively easy once you know the formula and required measurements. Read on to learn more about the assumptions underpinning superficial velocity and how to calculate it yourself. The Superficial Velocity Formula ...
How to calculate the velocity of a pendulum A pendulum has a period of 13.45 seconds. (a) How long is the pendulum? (b) What is the frequency of the pendulum? How to measure the oscillation of pendulum If a pendulum has a length of 5 meters, what will be the period of the pendulum...
Step 2: Substitute these quantities into the equation {eq}\tau = |r|\ |F| \sin{\theta} {/eq} to calculate the torque. Step 3: Apply the right hand rule to determine the direction of the torque. Formula and Vocabulary for Calculating Torque Torque: Torque, {eq}\tau {/eq}, is...
