Momentum is a measurement of an object's motion, taking into account both its mass and velocity. It is often described as the "quantity of motion" of an object.
Momentum is calculated by multiplying an object's mass by its velocity. The equation for momentum is: p = m * v, where p is momentum, m is mass, and v is velocity.
Conservation of momentum is a fundamental law in physics that states that the total momentum of a closed system remains constant. In other words, the total momentum before an event is the same as the total momentum after the event.
When a ball is falling, its momentum is constantly changing as it accelerates due to gravity. However, according to the law of conservation of momentum, the total momentum of the ball and the Earth remains constant throughout the fall.
The momentum of a falling ball is affected by its mass and velocity. A heavier ball or a ball with a higher velocity will have a greater momentum compared to a lighter ball or a ball with a lower velocity.
