i was bored nd like i lowk needa post smth so i thought y not talk abt the unit we js had in science LMAO anyways, there are 3 basic laws of motion these three are . . . — Law #1 (also known as the "Law of Inertia") this law states that an object in motion stays in motion unless it is stopped by another force. what this means is that if u roll a ball in a straight line, it will keep rolling forward. but this ONLY occurs in a frictionless environment bcs when u roll a ball on earth, it stops due to friction. friction is the opposing force in this scenario. however, if there was no friction the ball would js keep rolling in a straight line and never stop. another example is when ur in a car and it suddenly stops and u jerk forward. an object in motion stays in motion, so since u were in motion u stayed in motion even tho the car stopped. — Law #2 (also known as the "Law of Mass & Acceleration") acceleration is the change in speed of an object. if we represent the mass of an object as the variable "m", the acceleration as "a", and the force needed to accelerate the object as "f", then we can derive from this law that f = m x a, which means the force needed to accelerate an object is equal to the mass of the object multiplied by the acceleration. from this law we can also figure out why it takes more force to move a heavier object (bcs the mass is greater, so the force needs to increase in order to move the object at the same rate or acceleration) — Law #3 (also known as the "Law of Action & Reaction") this law states that for every action, it returns an equal amount of force as the reaction. this may sound confusing but lets look at some examples. when u push down on the floor, the floor returns the same force back to u which is what allows u to move forward while walking. another easier to understand example is when u turn on a hose at the greatest force, u need to step back bcs of the force of the water coming out from the hose. the water pushes against the hose, nd the hose returns the same force which boosts the water out, while also transferring the force to the person holding it. anyways yea thats my version of the description it kinda sucks but like i have nothing else to post but if u wanna know more i suggest u google lmao also correct me if im wrong, i didnt exactly listen the entire time in class
