Which of the following equations are dimensionally correct? f=ma x=1/2at^3 e=1/2mv e=max v=fxlm

F=ma

Explanation:

Among the given equations there is only one correct, we can know this with the dimension analysis of the units:

This is the equation that represents Newton's second law, where the force has unit of Newtons (). In addition we have the mass () in kilograms () and the acceleration () in ().

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
