Answer:
The change in momentum increases because the impact time increases.
Explanation:
The change in momentum of an object is also called impulse (J), and it is equal to
[tex]J=F \Delta t[/tex]
where
F is the force applied to the object
[tex]\Delta t[/tex] is the time taken for the change in momentum of the object to occur (the impact time)
From the formula above, we can notice that:
- the larger the force, the larger the change in momentum
- the larger the impact time, the larger the change in momentum
In the example of the baseball caught by the glove, when the glove moves backward, the time taken for the ball to stop increases (due to the movement of the gloves). Looking at the formula, we see that this means that the impulse (the change in momentum) increases.
Answer:
The change in momentum stays the same because the ball still comes to a stop.
Explanation:
here we know that momentum is defined as the product of mass and velocity
so here we know that
[tex]P = mv[/tex]
now we know that formula to find the change in momentum is given as
[tex]\Delta P = mv_f - mv_i[/tex]
[tex]\Delta P = m(v_f - v_i)[/tex]
now when player moves his hand backwards then in this case final speed of the ball is zero and initial speed is same
So here we can say that there is no change in the equation but only the the to stop the ball is increased.
So here change in momentum will remain the same
