Kinetic energy is simply the "power potential" of the arrow at the target, based on its mass weight and speed. Momentum can be thought of as the ability to put that power to work, penetrating the target. Light weight arrows at high velocity may have lots of kinetic energy, but generally, heavier arrows generally provide greater momentum ...

Staying with the mathematical approximation, the total energy of a pendulum is always constant, getting transformed from potential energy into kinetic energy and vice-versa. To calculate these quantities at any point in the pendulum's movement, we need to know the mass of the pendulum, as well as its vertical height.

A crush or energy analysis is the scientific process of quantifying energy for the purpose of determining speeds associated with a crash event. A vehicle running into something solid will suffer crush damage as its forward motion suddenly stops. The kinetic energy a vehicle has because of its respective speed is absorbed by the body of the vehicle.
The concept of kinetic energy, from which impact energy is derived, originated in the 17th century. Gottfried Wilhelm Leibniz proposed kinetic energy, distinguishing between the inherent energy of motion (vis viva) and rest (vis mortua). ...

When more kinetic energy is obtained by transforming the material into crushing energy, the feed is crushed better. According to the working principle of VSI crushers, the kinetic energy obtained by the feed comes from the high-speed rotating rotor. The size of the rotor kinetic energy is determined by the rotor speed which plays a

If an object of mass m= kg is dropped from height h = m, then the velocity just before impact is v = m/s. The kinetic energy just before impact is equal to its gravitational potential energy at the height from which it was dropped: K.E. = J. But this alone does not permit us to calculate the force of impact!
