When a baseball is dropped, it experiences a downward force due to gravity. This force causes the ball to accelerate towards the ground at a rate of 9.8 meters per second squared.
According to the principles of physics, the speed at which a baseball hits the ground when dropped from a certain height is directly proportional to the square root of that height. This means that as the height increases, the speed of the baseball also increases.
Yes, air resistance does affect the speed of a baseball when dropped. As the ball falls, it experiences air resistance, which is a force that opposes its motion. This force increases as the speed of the ball increases, eventually reaching a point where it balances out the force of gravity and the ball reaches a constant speed known as terminal velocity.
According to Newton's second law of motion, the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This means that a heavier baseball will experience a smaller acceleration due to gravity compared to a lighter baseball.
No, according to the law of conservation of energy, the total mechanical energy of a system remains constant. When a baseball is dropped, its potential energy (due to its height) is converted into kinetic energy (due to its motion). This means that the baseball will always have a non-zero speed when it hits the ground.
