Newtons Laws of Motion Newtons First Law What does this mean What is meant by unbalanced as long as ce
Riddle, Joe, Executive Producer has reference to this Academic Journal, PHwiki organized this Journal Newtons Laws of MotionNewtons First Law An object at rest tends to stay at rest in addition to an object in motion tends to stay in motion unless acted upon by an unbalanced as long as ce.What does this meanBasically, an object will keep doing what it was doing unless acted on by an unbalanced as long as ce.If the object was sitting still, it will remain stationary. If it was moving at a constant velocity, it will keep moving.It takes as long as ce to change the motion of an object.

Newtons First Law is also called the Law of InertiaInertia: the tendency of an object to resist changes in its state of motionThe First Law states that all objects have inertia. The more mass an object has, the more inertia it has ( in addition to the harder it is to change its motion).What is meant by unbalanced as long as ceIf the as long as ces on an object are equal in addition to opposite, they are said to be balanced, in addition to the object experiences no change in motion. If they are not equal in addition to opposite, then the as long as ces are unbalanced in addition to the motion of the object changes.Some Examples from Real Life Two teams are playing tug of war. They are both exerting equal as long as ce on the rope in opposite directions. This balanced as long as ce results in no change of motion.A soccer ball is sitting at rest. It takes an unbalanced as long as ce of a kick to change its motion.
More Examples from Real LifeA powerful locomotive begins to pull a long line of boxcars that were sitting at rest. Since the boxcars are so massive, they have a great deal of inertia in addition to it takes a large as long as ce to change their motion. Once they are moving, it takes a large as long as ce to stop them.On your way to school, a bug flies into your windshield. Since the bug is so small, it has very little inertia in addition to exerts a very small as long as ce on your car (so small that you dont even feel it).If objects in motion tend to stay in motion, why dont moving objects keep moving as long as everThings dont keep moving as long as ever because theres almost always an unbalanced as long as ce acting upon it.A book sliding across a table slows down in addition to stops because of the as long as ce of friction.If you throw a ball upwards it will eventually slow down in addition to fall because of the as long as ce of gravity.In outer space, away from gravity in addition to any sources of friction, a rocket ship launched with a certain speed in addition to direction would keep going in that same direction in addition to at that same speed as long as ever.
Newtons Second LawForce equals mass times acceleration.F = maAcceleration: a measurement of how quickly an object is changing speed.What does F = ma meanForce is directly proportional to mass in addition to acceleration. Imagine a ball of a certain mass moving at a certain acceleration. This ball has a certain as long as ce. Now imagine we make the ball twice as big (double the mass) but keep the acceleration constant. F = ma says that this new ball has twice the as long as ce of the old ball.Now imagine the original ball moving at twice the original acceleration. F = ma says that the ball will again have twice the as long as ce of the ball at the original acceleration.More about F = maIf you double the mass, you double the as long as ce. If you double the acceleration, you double the as long as ce.What if you double the mass in addition to the acceleration(2m)(2a) = 4FDoubling the mass in addition to the acceleration quadruples the as long as ce.So what if you decrease the mass by half How much as long as ce would the object have now
What does F = ma sayF = ma basically means that the as long as ce of an object comes from its mass in addition to its acceleration. Something very small (low mass) thats changing speed very quickly (high acceleration), like a bullet, can still have a great as long as ce. Something very small changing speed very slowly will have a very weak as long as ce.Something very massive (high mass) thats changing speed very slowly (low acceleration), like a glacier, can still have great as long as ce.Newtons Third LawFor every action there is an equal in addition to opposite reaction.What does this meanFor every as long as ce acting on an object, there is an equal as long as ce acting in the opposite direction. Right now, gravity is pulling you down in your seat, but Newtons Third Law says your seat is pushing up against you with equal as long as ce. This is why you are not moving. There is a balanced as long as ce acting on you gravity pulling down, your seat pushing up.
Think about it What happens if you are st in addition to ing on a skateboard or a slippery floor in addition to push against a wall You slide in the opposite direction (away from the wall), because you pushed on the wall but the wall pushed back on you with equal in addition to opposite as long as ce. Why does it hurt so much when you stub your toe When your toe exerts a as long as ce on a rock, the rock exerts an equal as long as ce back on your toe. The harder you hit your toe against it, the more as long as ce the rock exerts back on your toe ( in addition to the more your toe hurts).ReviewNewtons First Law:Objects in motion tend to stay in motion in addition to objects at rest tend to stay at rest unless acted upon by an unbalanced as long as ce.Newtons Second Law:Force equals mass times acceleration (F = ma).Newtons Third Law:For every action there is an equal in addition to opposite reaction.
