the magnitude of velocity is th esame as speed.
speed = distance/time
acc= change in speed/change in time
Equations of motion(for constant acc)
v=u+at
2as=v^2-u^2
s=ut+0.5at^2
where
v= final velocity
u=initial velocity
a=acceleration
s=displacement
t=time

Speed is the magnitude of the velocity which is a vector: Speed is expressed as m/sec and is independent of direction.
velocity = distance / time (direction is important in velocity) and its units are m/sec
Acceleration = Change in velocity / time and is also a vector. Its units are m/sec.sec

speed:
s = d / t , where d is the distance travelled, t time taken to travel
Velocity is the same as that of speed formula but with vector or direction of travel.
Acceleration:
a = (Vf - Vi) / t , where Vf is the final velocity, Vi is the initial velocity, and t is the time taken.

Perimeter = length x width length = 4(width) 420 = length x width 420 = 4(width) x width (420 = 4width^2) / 4 ^a million/2 is comparable to sq. root one hundred and five = width^2 10.247 = width

Speed(meters/second)= distance (meters)/ time(seconds)
Velocity(meters/ second, minute, hour)(direction)= distance (meters)/time (sencond, minutes, hours) (velocity has a direction though)
Acceleration= (ending speed - beginning speed)/ seconds
