WebSep 19, 2024 · If a reaction takes less time to complete, then it’s a fast reaction. 1/t just gives a quantitative value to comparing the rates of reaction. Obviously the one that finished in less time is quicker, 3 times quicker, which is shown by 1/t. How do you calculate stopping time? 60 MPH = 88 fps. (fps=1.467 * MPH). In physics, time is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics, it is a scalar quantity (often denoted by the symbol ) and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields.

WebDividing m/s by m/s^2 is the same as m/s * s^2/m (just the reciprocal of m/s^2). You would get s. The time in the air is only affected by the vertical component of the vector (s*sin (theta)), because gravity only acts on the vertical velocity. From the equations above, you can calculate t = v / a. WebRight Lines: Distance is the difference between two locations along your track. To find your speed you also need a time interval, the difference between two times on the clock (when you were at the locations). So speed is calculated from difference in location along the track and difference in time (of day). WebApr 18, 2024 · How do you find the height in physics? Determine how high the projectile traveled above its initial height by using the following formula where V is the initial vertical velocity and T is the time it takes to reach its peak: Height = V * T +1/2 * -32.2 ft/s^2 *T^2 For example, if you had an initial vertical velocity of 32.14 ft/s and a time of ... mantralingua website
