This means that something is going to stay still if nothing is pushing force onto it to make it move.
This also means that if something is going in a straight line then it will continue to do so until something stops it.
Gravity Is Cool
When someone pushes another person. The thing that causes the person to fall is gravity that’s pulling the person down to the ground.
Hey!
"For Example..." 3x
An example could be when someone is on a swing and only starts moving when someone starts pushing them. If it weren’t for that person then they would’ve never moved.
A basketball rolling across the ground and slowly stopping is an example of Newton’s first law as the thing stopping it is the rough ground. So me kicking the ball is science!
An example is a pencil sitting on a desk. There is no force acting on the pencil when on the desk that would make it roll off meaning that the pencil will continue to sit on the desk.
It’s the law of inertia because it proves that everything has inertia that goes against the change of forces.
What's The Point?
Newton’s First Law is important because it tells about how things move and stay in place. It helps us move things and helps us know how to stay in place. If it didn't exist then we wouldn't be able to move anything!
Gravity is what makes things that act upon each other actually have an effect.
We Need This Law For A Lot Of Things
To Move Or Not To Move Is The Question
~Stars That Made Up Our First Law~
Newton discovered this law by being inspired by Galileo that was wondering if the ground was smooth and would an object stop or not. He was also inspired by Descartes’s first law of nature which is where he got the part that the state of motion won’t change unless something acts upon it. So basically he put the two ideas together and then BOOM- first law created.
I don't like thinking about gravity, it always brings me down ;)
What if we didn't have inertia, gravity, or anything with Newton's first law?
I'm glad we have gravity, without it we would just have gravy. c;
Newton’s First Law is useful for playing sports like when you kick a ball for soccer or hit a baseball with a bat. More examples like shaking a tree to get something out, a rock sitting outside, or picking up your cup to drink out of it. We need this to be able to have fun and do things.
