WebbStep 1: State the known values. Maximum speed, v max = 12 m s-1 Amplitude, A = 1.4 m Step 2: Write down the equation v max = ωA. Step 3: Rewrite angular velocity in terms of frequency f. ω = 2πf. v max = 2πfA. Step 4: Rearrange for … WebbThis equation is important! For example, an object of mass 500kg has a velocity of 12 m/s, what is its kinetic energy? KE = 0·5 x 500 x 12 2 = 36,000J. (See also the KE of a Car). The kinetic energy of an object is directly proportional to its mass. This means that if you double the mass you also double the kinetic energy (for the same velocity).

Average velocity v ¯ is defined as displacement divided by the travel time. In symbols, average velocity is v ¯ = Δ x Δ t = x f − x 0 t f − t 0. The SI unit for velocity is m/s. Velocity is a vector and thus has a direction.
WebbFinal speed equation gcse - We can calculate the final speed of an object if we know how fast it was originally travelling (its initial speed) and its. Math Guide. Final speed equation gcse.
WebbAcceleration is the rate of change of velocity and its units are m/s². It can be calculated by dividing the change in velocity by the time taken. This equation can be rearranged into v = u + at, where v is the final velocity, u is the initial velocity, a is … WebbThe speed equation is one that you need to be able to recall and apply: v = speed (m/s) s = distance (m) t = time (s) Before you ask ‘why is speed ‘v’ and distance ‘s’? The reason is because ‘v’ and ‘s’ really stand for velocity and displacement but we are using them for speed and distance as well.
