One afternoon Nicholas was playing with his new toy car. He wanted to see if It could move by itself but he ended up seeing the car would move by itself.
Balanced
Calm Down Nicholas your car won't move because you haven't even pushed it.
I mean come on you've heard of newtons first law of motion right?
After finding out that her brother doesn't know about newtons first law of motion Rachel decided that she teach it to him herself.
No is that a type of food because I'm hungry
No newtons first law of motion is the law of inertia and it states that an object at rest will stay at rest unless acted upon by an unbalanced force. Lets take a closer look outside.
Balanced
The first part to the law of inertia states that an object at rest will stay at rest unless acted upon by an unbalanced force.
Balanced
Give it a push for me
Right Now Your car is at rest which is the first part of the law. An object at rest will stay at rest.
The second part of the law of inertia states that that object will stay at rest unless acted upon by an unbalanced force in this case it's when Nicholas pushed the car with a lot of force.
Wow, but hey why is my car slowing down Rachel
Once you pushed the car it started to move because there was an unbalanced force.
Unbalanced
That's something called friction and that brings me to the final part of the first law of motion lets go to the kitchen.
Nicholas saw as the friction of the grass started to slow down the car after he pushed it. The third part of the first law of motion states that the object will continue to stay in motion at a constant speed unless acted upon by an outside force.
Now Nicholas after you pushed the car you made the car move. Once the car started moving friction got stronger and stronger eventually being stronger than the force of your push stopping the car and making the car balanced again
That's cool and all, but why are we in the kitchen.
Well, the third part of the law of inertia states that the object will continue to stay in motion at a constant speed unless acted upon by an outside force. The floor has less friction than the grass so it would move until the friction can stop it and make it balanced.
Unbalanced
Yes, my car wouldn't move because I didn't put force for it to move. If I was to push it I would be the unbalanced force and I would make it move at a constant speed until friction or another outside force stops it and that is all under Newtons first law of motion.
After a long day of explaining Nicholas finally understands why his car wouldn't move earlier thanks to his big sister Rachel
Alright so do you get it now.
Yes, you finally get it now GET OUT OF MY ROOM!!!
