Physics
Capacitor Energy & Charge Calculator
Calculates the energy stored in a capacitor and its remaining energy at any point during discharge through a resistor. Use it when designing RC circuits, timing circuits, or energy storage systems.

Physics
Force Calculator (Newton's Second Law)
Calculate the net force on an object from its mass and acceleration using Newton’s Second Law, F = m·a. The cornerstone of classical mechanics, used everywhere from sizing motors to estimating brake forces to predicting how hard a ball will hit the ground.
