Physics equations
Essential physics formulas include acceleration as change in velocity over time, velocity as distance over time, force as mass times acceleration, work done as force times distance, power as energy transferred over time, volume as length times depth times breadth, pressure as force divided by area, density as mass divided by volume, and charge as current times time.
Acceleration
Acceleration = change in velocity/time taken
