Concept of mass and force Mass of a body is the quantity of matter in it, which is assumed to be constant . Mass gives a body its inertia (ability to move or stop) Weight is the magnitude of the force that the earth exerts on the body . 1 N is the force that will give a 1-kg mass an acceleration of 1m/s^2.

### What students are saying

• 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.
