All sellers making retail sales of taxable goods or services in Nebraska are required to register with the state and collect and remit sales tax. As Nebraska is a Streamlined Sales Tax state, out-of-state businesses without a sales tax obligation are encouraged to register for sales tax purposes.
Since the kinetic energy increases with the square of the speed, an object doubling its speed has four times as much kinetic energy. For example, a car traveling twice as fast as another requires four times as much distance to stop, assuming a constant braking force.
The higher the speed at which something is moving, the more kinetic energy it has. For a given speed, the amount of kinetic energy is proportional to the mass of an object. If equal volumes of air and water are moving at the same speed, the water will have much more kinetic energy because of its much greater mass.
