Kinematic equations to memorize and circumstances when to use; kinematic equations are only applicable when acceleration is constant.
Equation 1) Velocity as a function of time
Vf = Vi + at
Equation 2) displacement w. time + velocity
d = vi t + 1/2(at2)
Equation 3) displacement as a function of initial + final velocity
d = (( Vi + Vf) t ) / 2
Equation 4) final velocity as a function of displacement
V2f = V2i + 2ad
What equation is used when we know time + acceleration and need to find velocity?
Equation 1; Vf = Vi + at
What equation would we use when solving for displacement and we have initial velocity, acceleration, and time?
d = vi t + 1/2(at2)
What equation would we use when solving for displacement and have both velocities?
d = (( Vi + Vf) t ) / 2
What equation would we use when solving for final velocity but arenโt given time?
V2f = V2i + 2ad
