Velocity, on the other hand, is your speed and direction. It is a vector because it does have a direction. For example, 3 miles per hour is a speed, but 3 miles per hour south is a velocity. Since an object moving in a circle is constantly changing direction, its velocity is constantly changing.

Dec 02, 2019 · Newton realized that when the ball is propelled at a certain, magic velocity, it will never fall. At this velocity, the ball will trace the linear surface; basically, it travels horizontally, but never vertically, because as soon as it falls, the Earth beneath it curves: the ball falls at the same rate as the Earth curves.

Example: at a length of 10 and a height of 5 meters, the angle of slope is 30°, the velocity of a ball is 7.3824 m/s and the time to get there is 2.7091 seconds. Slope: h = l * sin (α), l>h, 0°<α<90° S = (v+u)/2 x t. Where S = distance moved by the bullet, v = final velocity, u = initial velocity, t = time. S = (0 + 20) / 2 x 0.1. S = 1m. Therefore, distance moved by the bullet in the wood = 1m. See more calculations based on Newton's second law of motion.
