Integrated Physical Science: Semester 2 Exam Review
... 24. What is the difference between mass and weight? Explain what the term losing “weight” really means. Mass is how much matter you are made up of. Weight is how much force gravity is accelerating your mass. Depending on the gravitational force of an object it will have a certain gravitational acce ...

General Relativity for Pedestrians-
... Gravity is universal. Everything creates gravity as well as gets affected by gravity since everything has mass (or, equivalently, energy). However, unless the mass of an object is very large, the gravity it generates is very weak. According to Newton’s laws of gravity, acceleration of a test particl ...
