Mass and Newton’s 1st Law

this pictures shows the correlation between inertia and Newton’s 1st Law, and the amount of mass something has , well because as you can read in the pictures it says that with no outside forces, this object will move.
                                                                                             



                                                                                            This tree examples shows the correlation                                                                                                      between inertia and Newton’s 1st Law, and the                                                                                                amount of mass something has because small                                                                                                amount mass the larger the acceleration and                                                                                                  the lager amount of mass the smaller the                                                                                                         acceleration. This pictures shows that.
this picture shows the correlation between inertia and Newton’s 1st Law, and the amount of mass something has because if the ball had more mass the girl have to kicked harder in order for the ball to go far.



This picture shows the correlation between inertia and Newton’s 1st Law, and the amount of mass something has because it showing how the both object have the same force but they are going in different speed because one object have more mass then the order.

Inertia Investigation

 when i'm playing ball with my little brother in the park , the ball some times goes to this down hill but that down hill goes up after so therefor the ball goes back and front it never stops because there is no friction force.




 As you see this ball is stopping really quickly because there is fiction acting upon it. This means that something else is stopping the ball

Mass and Newton’s 1st Law

three examples in my life that show the correlation between inertia and Newton’s 1st Law,

             (pulling a tablecloth)

  when you're pulling a tablecloth the staff that is on it whats to stay the same. you are pulling only the cloth in order for the staff on top to not move you have to pull the cloth very fast (velocity)

               (eureka-mass)

the amount of mass doesn't depend on size.

Mu - Friction

Friction happens when one object slides along another object. It is the force that resists the relative motion between the two surfaces. Friction occurs in the opposite direction of the moving object's motion and reduces its speed.
                 names of another surface that i think would have an even bigger value of μ with my shoe. 
                                        *wood floor
                                        *ceramics floor
                                        *glass
                                        *plastic 
                                     

Free Body Diagrams

                          

                          FN=-8N

                                                     FG=8N

                                                      FF=-5N

                                                      FA=5N

the block is not moving since all the forces have the same amount. I'm pushing the block with both hands and my sister is pulling the block too. Which means that i will be the applied force and my sister is the friction force. The normal force would be the table where is at which is going against gravity force .The gravity force which is pulling the block down.

Balanced and Unbalanced

    Balance: the net force equal zero.
   Unbalance: the net force doesn't equal zero.
               (this all are unbalance)
                        
                              - applied force
                              - tension force
                             


                      (this is balance)
                            



                   

Vectors & Scalar

       The difference between vector and scalar is that in scalar the direction doesn't matter and in vector the direction does matter.
