Question
I'm taking a college conceptual physics class and i need i'm aloud to use equations as long as i convert the equation from the concept to the equation. so basically what i need is how to convert the concept to the equation. i need it for when i need to find a force, an acceleration, a distance, a velocity/speed, momentum, kenetic and positive energy, and a time. one of my teachers examples was d~t^2 was the concept and i think it somehow converted to the sum of d=vt+1/2 at^2 or something like that. plz help me if you can.Explanation / Answer
Position (x) as a function of time (t) given initial position (x0), initial velocity (v0) and constant acceleration (a):
x = x0 + v0t + 0.5at2
Velocity (v) as a function of time (t) given initial velocity (v0) and constant acceleration (a):
v = v0 + at
Force (F) as a function of mass (m) and constant acceleration (a):
F = ma
Momentum (p) as a function of mass (m) and constant velocity (v):
p = mv
Kinetic energy (Ek) as a function o mass (m) and constant velocity (v):
Ek = 0.5mv2
I'm not sure what you mean by "positive energy".
