Intro In Physics: What I Know

By: Sania Khan

Objects move in this world due to the gravitational force. Some of the things are meant to move vertically because of their shapes and sizes. If they are for example a table, due to it's shape it can only move horizontally and not vertically. But for something like a balloon, that can only move vertically because of the elements that make it, like helium only allows it to go up or vertically. Some of the objects stay stationary due to how they are, like if they are not able to move then maybe it's because of their weight and therefore they are very heavy to move. The movement speed matters since the speed of the object depends on the size and the weight. The weight is a big factor in the movement of the object and therefore because of the weight the objects are able to move up and down.
