Physics- lecture 1
Question | Answer |
---|---|
Acceleration | A=∆v/timeVelocity and acceleration don’t have to be in the same direction.Ex) a ball thrown up is accelerating down. |
Net displacement | square each distance and add. Then take the square root. |
Velocity | V=displacement/timeIf displacement is 0 then V=0 |
Linear motion equations (require constant acceleration) (think projectile) | X=x₀ + v₀t + ⅟₂ at²V= v₀ + atv²=v₀² + 2ax |
average velocity | Avg. V = ⅟₂ (v+v₀) |
