Physics Equations Flashcards
Kinematic equation if X is not given or shown.
V = Vo + at
Kinematic equation if a is not given or shown.
X = 1/2 (V + Vo)t2
Kinematic equation if V is not given or shown.
X = Vot + 1/2 at2
Kinematic equation if t is not given or shown.
V2 = Vo2 + 2aX
What is Newton’s first law?
Objects in rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force.
What is Newton’s second law?
Force = mass x acceleration
What is Newton’s third law?
for every action there is an equal and opposite reaction. (Normal force)
Work formula
Force x distance cos (Ø)
Ø is the angle between the force and direction of motion
First Law of Thermodynamics
buoyant force equation
continuity equation
Electro static force equation
Electrostatic Field equation
Electric potential
Kq1q2 / r
*graph wise, potential energy is always decreasing
Ohm’s law
Magentic Force
Left hand trick keep thumb aligned with the current qv
fingers alligned with the magnetic field
and magnetic force point out of palm
Magnetic Field equation
thumb will represent the movment of positive charges while we wrap our fingers around wire giving us direction of the field.
The equation illustrated Is just for a straight wire if your doing a cicular loop just don’t use 2π
period-frequency relation
Doppler shift
Snell’s law
mirror and lens equation
F = 1/2 r
Mirror equations
- -When M is negative is inverted
- -When M is positive it is Upright
- -When I M I Is less than one than image is reduced
- -When I M I Is greater than one than image is big
- -When i is same side as source is virtual
- -When i is opposite side of source is real
- -When r is positive it’s a concave ) mirror
- -When r is negative it’s a convex ( mirror
Lense equations
- -When M is negative is inverted
- -When M is positive it is Upright
- -When I M I Is less than one than image is reduced
- -When I M I Is greater than one than image is big
- -When i is opposite side of source is real
- -When i is same side as source is negative
- -When r is negative it’s a concave ) lense
- -When r is positive it’s a convex ( lense
