A ball is dropped from a 100m cliff. at the same time another ball is thrown up such that it has enough velocity to reach the top. at what distance from top of the cliff will the two balls meet?
Kinematics is a branch of physics that deals with the motion of objects without considering the causes of that motion.
The velocity of the ball increases as it falls due to the acceleration of gravity.
The higher the height from which the ball is dropped, the greater the final velocity will be due to the increased potential energy it has at the higher starting point.
The formula is v = √(2gh), where v is the final velocity, g is the acceleration of gravity (9.8 m/s²), and h is the height from which the ball is dropped.
Air resistance, also known as drag, will act on the ball as it falls and will decrease its acceleration and final velocity. This effect is more noticeable for objects with larger surface areas, such as parachutes.
