Now, it’s easy to realize that the Earth wear Mask Help Me Coronavirus T-shirt second force won’t contribute to changing the intensity of your linear velocity as long as it’s perpendicular to your movement. (The work is done with zero and the change of kinetic energy is because of it. You go away. Replace you with a river and the system is your earth, where gravity always acts horizontally, ie perpendicular to a body moving on its surface, as long as it is a homogeneous sphere.Getting the analogy.
Your thrust river. Is the result of the downhill, which too. The Earth wear Mask Help Me Coronavirus T-shirt gravity course works down but only part of it is used to balance the normal reaction force while the rest act as you move and accelerate for you. Meanwhile, going up a slope, gravity acts in the opposite direction of your movement and slows you down. Why is it deep in the distribution of large nebulae but the Earth is slowing down from 8 hours to now 24 hours.
