MY KITTY NAMED NEWTON Kami Ward Madi Thomas Jaclyn O’Dell
Sally decided she wanted to take a trip to the park. She wants to her kitty, Newton, with her. “I wanna ride on the slide, swing on the swings, and we can even play with a bouncy ball together Newton!” Sally said. Newton replied, “Ok Sally! We can play there all day if you want, and we might even learn something today!”
Sally and Newton get to the park. “Hey Newton! Lets go play on the swing!� Sally says. Newton and Sally head over to the swing set so that they could play.
“You know Sally, swinging on these swings reminds me of a certain rule in science by a guy that has my name. It’s called Inertia and it has to do with one of three laws. Its says: An object that’s moving will keep moving unless it is stopped by a force, like me! Also, something that is sitting still will stay that way unless moved.”
“Wow, I didn’t know that! You said there were three laws though, can you tell me about those too?” Sally said. “Of course Sally! Lets go play on the slides and I’ll tell you more.” Newton said.
“The second law says that the force needed to accelerate an object equals the mass times its acceleration, or Force= Mass x Acceleration. You also gain more momentum as you slide down the slide, and some friction might slow you down a little bit. To put it easier though, the harder you push something the faster or longer you will go. So if I push you really hard down the slide you’ll go fast, and if I push you soft then you won’t go as fast.” Newton explained.
“Oh well that’s interesting! Can we go play with the bouncy ball now?” Sally said. “Let’s go!” Newton exclaimed.
“You know Sally, Newton’s 3rd law states that for every action there is an equal and opposite reaction. So, the harder you bounce the ball, the higher it will bounce.” Newton said. “Oh, that’s cool. I didn’t know that! I learned a lot today and I had fun with you, but I think I’m getting tired. Let’s go home, Newton.” Sally replied.
After a long day of learning, Sally and Newton left the park and were on their way home. Sally learned Newton’s three laws of motion and got a full day of fun out of it.
Glossary Acceleration- increasing in speed; getting faster Friction- the rubbing of one object against each other Force- ability to do work or cause physical change Inertia- tendency of an object in motion to stay in motion, or an object at rest to stay at rest unless acted on by another force Mass-the quantity of inertia possessed by an object or the proportion between force and acceleration Momentum-the power to increase or develop at an ever-growing pace
Velocity-the speed at which something moves or happens
