If you have an object on top of a table at rest it will remain at rest unless force is applied to move it.
Ms.anderson's car, which weighs 500 kg, is out of gas. she is trying to push the car to a gas station, and she makes the car go 0.10 m/s. Using Newton's Second Law, you can find out how much force she is is applying to the car.
When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body.
For every action there is an equal and opposite reaction.
force=mass*acceleration
All my examples connect because all of them were having equal and opposite reactions toward the force
I remember in the beginning of this unit i thought this was useless because its not like you are going to stop your day and talk about laws of motion or its not like your going to be a physics teacher.at the end of the term i finally noticed that we need to know the newtons laws so we can still be alive and not try to fight the force it feels real good knowing that this newtons laws will apply to me in my real world situations.This will help me find out how much force am i using to push car or push an empty box which i always try to test my strength.
Newtons 1st law,newtons 2Nd law,newtons third laws what is the based importance of these laws you may ask.well all these laws are important because they determined whether the object has balanced or unbalanced force or whether if the object will stay at rest.For example if you want to jump on a bed you need to know if the bed will remain at rest so you wont fall down and bust your head like the three little monkeys jumping on the bed.or lets say you are pushing a grocery cart but you want to speed up so you will know to increase the force your applying to the cart in order to make it speed up for you would not go home late.so before you say physics does not matter or before you try any thing crazy you have to go with the laws of motion.
in the examples,the forces that are applying to an object the object can be pushed or pulled because its equal and opposite reaction towards the object that also forms a force pair
An object at rest will stay at rest and an object in motion at a constant velocity unless acted upon by an unbalanced force
when there is an object that weights 200kg and you apply a force to it making it move 20m/s
When your in a car speeding and suddenly make a stop you move foward.
when you are in a sea saw it depends on the weight and if you and the other person has an unbalanced force which will mean that you or the other person will be an opposite reaction
-
when you are pushing a book to the other side that weighs 20kg and you push a balanced force of 20 m/s
when you are pushing against a table.
when an object i at rest but when you apply a force to it,it reacts to the applied force.
