KE: 5 x m x v squared
PE: m x g x h
property of a body that effect it state of motion neccessary component of motion according to aristotle indirect force resulting from the application of a force.
Law of inertia is the tendency of an object to continue moving. Law of inertia is also known as momentum. Mass is dependent on the inertia on motion, the bigger the mass the bigger the inertia in motion or momentum which makes the object to be more difficult to stop. Since inertia in motion is also known as momentum, and momentum is mass × velocity, we should also consider velocity contributes to inertia in motion.
Hope it helps=)
From a starting velocity of zero before its drop, the ball will gain speed during free fall, thereby increasing its velocity. As it falls faster it will encounter more wind resistance until it reaches a point wherein the force of the wind resistance is equal to its weight. At this point, the net force will be zero so the drop speed won’t be able to increase anymore which is Terminal Velocity.
So the ball’s speed increases as it falls until it reaches Terminal Velocity or the final speed possible for a falling object.
