Momentum

What is Momentum

The quantity of motion of a moving body, measured as a product of its mass and velocity.
Momentum= Mass*Velocity
P= M*V

Example in soccer, we compute the kg of the ball and the distance of the ball to the goal and the time of the ball to goal if the player kick the ball.

The weight of the soccer ball is 416kg
The distance of the ball to goal is 16.5m
The time that the ball travel to goal is 26s

So let's solve the problem.
In the formula we solve the products, so to solve this we get the mass and after that we divide first the distance and time. Like this.
First: P= 416*
In first steps we put the mass or weight of the soccer ball.
Second: 16.5/26
We divide the distance and time to get the velocity.
Third: 63.5m/s
We put the answer of the distance and time
Fourth: 416*63.5
So we after we get the velocity, we can now multiply the mass and the velocity to get the product.
Fifth: 26.4kg*m/s
So, in the last steps we get the total of product and the final answers.

In the problem we know that the momentum of the soccer ball to the goal is 26.4kg*m/s.
