WebApr 7, 2024 · Ans: Using the speed calculation formula, Speed = Distance/ Time $\dfrac{3600}{30 \times 60}$ = 2m/s = speed. Method for Measuring Speed. Most Americans measure speed in miles per hour or mph. In most cases, cars are measured by this method. In Physics, meters per second (m/s) is usually used to calculate speed. … unwind locationWebMar 16, 2024 · The kinetic energy equation is as follows: KE = 0.5 × m × v², where: m – Mass; and. v – Velocity. With the kinetic energy formula, you can estimate how much energy is needed to move an object. The same energy could be used to decelerate the object, but keep in mind that velocity is squared. recorded evidenceWebIn conclusion, speed and velocity are kinematic quantities that have distinctly different definitions. Speed, being a scalar quantity, is the rate at which an object covers distance.
