Lisa just couldn’t stand to see her Grandma looking so bad in the hospital. She decided not to go to the hospital until her mom said her Grandma looked better.

Lance thought he should give his friend Andy more time to get over his brother’s fatal car accident, so he didn’t invite him over for their usual video game night.

It was pretty hard, but Kelly just listened when her Grandma kept talking about her Grandpa after he died.

The situation in which the magnitude of the total force is greater than the magnitude of each of the individual forces is when four people stand on each side of a large box and all four people push the box with the same amount of force.
The situation in which the magnitude of the total force is greater than the magnitude of each of the individual forces is when four people stand on each side of a large box and all four people push the box with the same amount of force.
To understand why the total force is greater in this situation, we can consider the principle of vector addition. When forces are applied in the same direction, like in this case where all four people are pushing in the same direction, the magnitudes of the forces add up. So, the total force is equal to the magnitude of each individual force multiplied by the number of forces applied. Therefore, in this situation, since all four people are pushing with the same amount of force, the magnitude of the total force is four times the magnitude of each individual force.
In contrast, in the other situations mentioned, the forces are either in opposite directions or acting on the same side of the box. In these cases, the forces may cancel each other out or their magnitudes will simply add up and not exceed the magnitude of each individual force.
