Today I am writing about acceleration for my 8th grade science class. Today’s match-up is between an Elephant and a Mouse. The only catch is that I have to explain this using Sir Isaac Newton’s third law of motion. So, without further adieu, let’s get this show on the road with some acceleration!
The object that the two contestants need to move is a beach ball. Now that you know this, go ahead and decide which you think will send it farther… Now that you’ve done that, I think that the Elephant will send it farther. I think this because the Elephant weighs much more that the mouse, so then that would make it seem as though the Elephant would have more strength in its leg to kick the ball farther. Newton’s third law of motion states, “For every action, there is an equal and opposite reaction.” This being said, the mouse and elephant have to push the beach ball with more force than the beach ball has to keep itself still. For example, if you place a block on the floor, it won’t move right? However, once you push the block with a lot of force, it will move. This is what needs to happen to move the beach ball.
Well, now that we know that they will both be able to push the ball, which will go farther? This is obviously the elephant because it has more mass, and a higher chance to use the right amount of force to apply to the ball.
That being said, we must assume that the mouse is not somewhere near the elephant. Almost everyone knows that elephants are scared of mice, so the mouse can’t be near the ball, because then the elephant won’t come anywhere near the ball.
