Answer 2

Answer:

1. DUE TO INVERSE GRAVITY

2. DUE TO INERTIA

3. explain below

Explanation:

• THE EXPLANATION MAY BE LARGE....PLZ READ ONCE....I HOPE THIS WILL HELP YOU TO UNDERSTAND... ACTUALLY WHAT THIS MEANS.

1. For pulling a cart or for running, the horsepushes the earth with its feet and reaction of the earth makes it move in the forward direction. Since in empty space there is no reaction force or forced inversely by the cart on the earth., therefore the horse cannotrun in empty space.

2. This is happens due to the inertia which states that "the body will remain in motion/rest until an external force is applied on the body"

therefore,When the bus get stopped suddenly, our lower part come to the rest but upper part remain in the motion. so we suddenly pulled in the forward direction.

3. it is happens thus, the fielder increases the time during which the high velocity of the moving ball decrease to zero. Thus, the acceleration of the ball is decreased and therefore the impact of catching the fast moving ball is also reduced.

, the fielder increases the time during which the high velocity of the moving ball decrease to zero. Thus, the acceleration of the ball is decreased and therefore the impact of catching the fast moving ball is also reduced.If the ball stopped suddenly then its high velocity is decreased to zero in a very short interval of time......

that may appear to fielder negative impact.

★ BCOZ THE RATE OF CHANGE OF MOMENTUM OF THE BALL WILL BE LARGE.& THIS LARGE FORCE MAY WOULD HAVE TO APPLY HURT ON THE PALM DURING HOLDING THE CATCH.

I hope this explanation may help you.

if you satisfy with this.....,give feedback plz.
