True - Weight Watcher's participants only use a measurement of their weight as a reflection of how many atoms of flesh that they have burned from their bodies. False - An object has the same mass on Mount Everest as it does at sea level (or near sea level) only the weight of the object would be slightly different in these two locations.į. True - This is kind of a simple definition of mass but it does do the job (provided stuff means atoms or material).Į. Kilograms is for mass and Newtons is for force.Ĭ. (Weight on the other hand depends upon the gravitational environment.)ī. Because of this, mass is said to be invariable (unless of course, an object loses some of its atoms) - a constant quantity which is independent of the acceleration of gravity and therefore independent of location. False - Mass is independent of the gravitational environment that an object is in and dependent solely upon the number of atoms in the object and the type of atoms (Carbon: ~12 g/mol Hydrogen: ~1 g/mol Oxygen: ~16 g/mol).
The mass of an object is mathematically related to the weight of the object.Ī.If all other variables are equal, then it would require less exerted force to stop a less massive object than to stop a more massive object.If all other variables are equal, then an object with a greater mass would have a more difficult time accelerating.The mass of an object can be measured in pounds.People in Weight Watcher's are really concerned about their mass (they're mass watchers).An object would have more mass on Mount Everest than the same object in the middle of Lake Michigan.The mass of an object is variable and dependent upon its location.Mass depends on how much stuff is present in an object.The standard metric unit of mass is the kilogram.The mass of an object is dependent upon the value of the acceleration of gravity.Which of the following statements are true of the quantity mass? List all that apply. An alteration in the g value effects the weight of an object but not the mass or inertia of the object.Ģ. False - Once more (refer to g), inertia is unaffected by alterations in the gravitational environment. For instance, its the tendency of a moving object to keep moving at a constant velocity (or a stationary object to resist changes from its state of rest). False - Inertia is NOT the tendency to resist motion, but rather to resist changes in the state of motion. It still has the same tendency to resist changes in its state of motion. Yet it still maintains the same amount of inertia as usual. In a location where g is close to 0 m/s/s, an object loses its weight. False - Inertia (or mass) has nothing to do with gravity or lack of gravity. False - The speed of an object has no impact upon the amount of inertia that it has. Objects with greater mass have a greater inertia objects with less mass have less inertia.į. True - Mass is a measure of an object's inertia. (Any object without mass is not an object, but something else like a wave.)Į. The more mass which an object has, the more that it sluggish towards change.ĭ. Put another way, inertia is the tendency of an object to "keep on doing what it is doing." Mass is a measure of an object's inertia. Inertia is simply the tendency of an objects to resist a change in whatever state of motion that it currently has. In a gravity-free environment (should there be one), a person with a lot of inertia would have the same ability to make a turn as a person with a small amount of inertia.Ĭ.Inertia is the tendency of all objects to resist motion and ultimately stop.An object would not have any inertia in a gravity-free environment (if there is such a place).Fast-moving objects have more inertia than slow-moving objects.A more massive object has more inertia than a less massive object.Inertia is a force which brings all objects to a rest position.Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity.Which of the following statements are true of inertia?
