video video in the motion what is force Oracle that's what forces are push or pull that one body directions right here you got the force of gravity pulling force of the tables pushing back up on the apple and their balance on a table little kids Newton's first law of motion Villa Sport really nothing would ever not move without breaking everything Spurs lost moving some kind of four stops it from the first law can also be called the law of inertia inertia is a property of matter that resists sitting still the other dress you're driving in your car and you want to turn this way so you're going this way and you start to turn and your car starts going that way but your body the car is turning and so what causes. you're driving and you turn your body Lanes it's because your body has inertia it wants to keep you are in a car and you shoot something your body keeps moving for another car stop because your body has inertia to stop removing that is inertia for a small objects don't like that picture right there motorcycle stop it acceleration what is what will you measure force and acceleration acceleration and how much worth was used where to stop double the amount of sports alright so Newton's second law accelerate Sports gravity table Newton's second law the astronaut pushes on a rock and The Rock pushes The Rock because there's no friction forever we're going to go out of that set equal opposite forces do not result in acceleration two people yoga balls and they run at each other and smash into each other if that's a big person and a little person and they smash into each other so yeah that's that's important with different with each other wow how you get cereal first love stop force causes it to move out and put on pushing it. greater mass greater for saltwater water to make a bigger Splash stuff like that and then equal and opposite reaction reaction reaction down the waterslide so now another Force One of the force is one of the main fundamental forces of our universe is gravity gravity is a Down and you know is the number 8 meters per second squared acceleration acceleration due to gravity is 9.8 meters per second squared when you drop something another time another force is is gravity what is the type of course it is opposite of gravity what goes against gravity air resistance resistance is actually a type of friction are the type of friction between parachute opens up gravity pulling you down what down open up word turn down the air molecules are pushing up on the largest surface area so you can write that one as well free body diagram free body diagram write all this down grams or Force diagrams how much what the magnitude of the forces are set right here we have a 10 kg normal force if it's sitting something the normal force is that upward force of the surface you start push it force in that direction to make it so that is the life live across the 4th shows all of those different friction is a force that opposes motion friction is a force that opposes Charles Direct so there's lots of different types of friction sliding friction slide on top of another just rub your hands together rolling friction is with car rolls on top of another option stop object when I'm standing on top of the ground thinning out coming up that's friction friction like with air resistance that we were talking about is fluid air and water are both fluid and so the gas station in the water water molecules rubbing against this person here you got the gravity pulling down but then there are pushing up on this and so that are resistant free body diagram we will have to do that in the video that's all
