Consider the video demonstration that you just watched. A more complete explanation of what you saw will be possible after covering Newton's laws. For now, consider the following question: How would the result of this experiment change if we replaced the ball with another one that had half the mass? Ignore air resistance.

a. The ball would land behind the cart.
b. The ball would still land in the cart.
c. The ball would land ahead of the cart.

Option B : The ball would still land in the cart.

Explanation:

According to Newtons law, all bodies fall at the same time under gravity. The trajectory of a particle is a vector function of time not mass or weight.

Hence, these two proves that regardless the mass of a body, the trajectory only changes with time and direction, which in other words means The ball would still land in the cart regardless of changes in mass

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
