Detailed explanation-1: -v=final velocity. 1) average velocity= (u+v)/2. 2)acceleration = change in velocity / time.
Detailed explanation-2: -KE = kinetic energy m = mass v = velocity The definition of kinetic en-ergy for a mass m with veloc-ity v. PE = mgh. PE = potential energy. m = mass. g = acceleration due.
Detailed explanation-3: -Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth’s gravitational force as the acceleration rate of an object.
Detailed explanation-4: -voltage. also called electric potential difference. volt (V)
Detailed explanation-5: -v is the particle’s final velocity. a is the particle’s acceleration. t is the time interval.
