Inertia and Mass Inertia is a measure of an object ! s resistance to changes in its motion This resistance to change depends only the object ! s mass – The mass of an object is a measure of the amount of matter it contains SI unit of mass is kg Mass is an intrinsic property of an object – It is independent of the object ! s location – It is independent of the object ! s velocity or acceleration – Independent of it’s composition or any other property I"#946 2/(

Newton ! s Second Law Multiple forces act on an object simultaneously The total force on the object is the sum of these individual forces, The acceleration of an object with mass m is then given by: – Newton ! s Second Law is the link between force and motion It tells us how an object will move when acted upon by a force or a collection of forces total = !

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
