# physic's-key equations

?
Equation for speed , time and distance
speed = distance ÷ time

distance = speed × time

time = distance ÷ speed
1 of 5
Equation for magnification
Actual Length = length of the Image divided by the Magnification.

Magnification = length of the Image divided by the Actual Length.
