Newton's Laws & Kinematics
Classical mechanics describes how objects move under forces. Newton's Second Law (F = ma) relates net force, mass, and acceleration. Kinematic equations extend this to calculate displacement, velocity, and time for objects under constant acceleration — such as a car braking, a ball thrown upward, or a vehicle accelerating from rest.
This calculator handles the core kinematic equations and Newton's law, making it useful for physics students and engineers modeling motion. Enter the known variables and solve for any unknown. All quantities use SI units (newtons, kilograms, m/s², meters). Calculations run instantly in your browser.
