# Understanding Momentum and Conservation in Falling Balls

• Ereny
In summary, Momentum is a measurement of an object's motion, taking into account both its mass and velocity. It is calculated by multiplying an object's mass by its velocity. Conservation of momentum is a fundamental law in physics stating that the total momentum of a closed system remains constant. In relation to falling balls, the total momentum of the ball and the Earth remains constant throughout the fall due to the law of conservation of momentum. The factors that affect the momentum of falling balls include mass and velocity, with a heavier or faster ball having a greater momentum.

consider a ball falling to the ground.

a. why is momentum not conserved from the perspective of the ball? explain

b. define a system for which the momentum of the ball falling to the ground is conserved

Hi Ereny!

Show us what you've tried, and where you're stuck, and then we'll know how to help!

Hey tiny tim ;)!

I actually figured it out ...

## What is momentum?

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.

## How is momentum calculated?

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.

## What is conservation of momentum?

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.

## How does momentum relate to falling balls?

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.

## What factors affect the momentum of falling balls?

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.
