The adjective kinetic has its roots in the Greek word κίνησις kinesis, meaning "motion".The dichotomy between kinetic energy and potential energy can be traced back to Aristotle's concepts of actuality and potentiality.
At instant 1, a mass dm with velocity u is about to collide with the main body of mass m and velocity v. After a time dt, at instant 2, both particles move as one body with velocity v + dv. The following derivation is for a body that is gaining mass . A body of time-varying mass m moves at a velocity v at an initial time t.
Consider N = 2 particles with equal mass m, acted upon by mutually attractive forces. Suppose the particles are at diametrically opposite points of a circular orbit with radius r. The velocities are v 1 (t) and v 2 (t) = −v 1 (t), which are normal to forces F 1 (t) and F 2 (t) = −F 1 (t). The respective magnitudes are fixed at v and F.

2. New Jersey. The Garden State is known for being the most densely populated state in the country, but it’s also one of the most expensive for homeowners. The average property tax rate is 1.64%.

Magnetic vector potential was independently introduced by Franz Ernst Neumann [1] and Wilhelm Eduard Weber [2] in 1845 and in 1846, respectively to discuss Ampère's circuital law. [3] William Thomson also introduced the modern version of the vector potential in 1847, along with the formula relating it to the magnetic field.
The report also found that generative AI and other emerging technologies have the potential to automate the tasks which take up 60% to 70% of employees’ time at the moment—adding between $2.6 ...
