Read full descriptionHide full description
The Conservation of Momentum Calculator is a physics/math calculator designed to find the initial and final speed of two colliding objects. Features: - Instant calculation - Results are copyable to other apps - Formulas are included as reference - Supports up to 16 decimal places - Supports various units for each input - Lightweight app with a small size, optimized for everyday use The conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forces acting on the system. It is embodied in Newton's first law (the law of inertia). In Newtonian mechanics, linear momentum, translational momentum, or simply momentum (plural: momenta) is the product of the mass and velocity of an object. It is a three-dimensional vector quantity, possessing both magnitude and direction. If m is an object's mass and v is the velocity (also a vector), then the momentum is given by: p = m * v If the velocities of the masses are u_1 and u_2 before the interaction, and afterwards they are v_1 and v_2, then: m1u1 + m2u2 = m1v1 + m2v2 Where: m1: object mass 1, in Kg u1: object 1 initial velocity, in m/s v1: object 1 final velocity, in m/s m2: object mass 2, in Kg u2: object 2 initial velocity, in m/s v2: object 2 final velocity, in m/s Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.
