Forces

Forces & Newtons Laws First Law- inertia is an object that doesn't want to move basicly and object wont move unless a force is applied like locking the front brakes of a bike and flying forward while the bike stops second law- the sum of the forces acting on an object is net force, like your weight on the moon would be less than that on Earth but mass no matter where you would be would always remain the same because weight is the force of the ground pushing up against your feet. third law-definition= For every actoion there is an equal and oppsite reaction because there is no single force and all forces have pairs, normal force is when an object is in equalibrum which means the object won't contune to fall, friction is the force against a force or the reaction, the reason that you cant move a heavy object with little force is because of the static force, as long as it stays still the static force is equalk to that of the force that is applied. Kincetic friction is the force against an object while it is moving because of the surface the object is pushed on is probably rough which means there will be friction to stop it, if an object is pushed on a perfectily smooth surface it would never stop due to no friction on the surface
