Can you please tell me the proper format for multiple response questions? I tried the following, but it only found 1 question.
Part A: Mass, Inertia, Weight, and Newton's First Law of Motion Multiple Response 1. Which of the following statements are true of inertia? List all that apply. a. Inertia is a force. b. Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. c. Inertia is a force which brings all objects to a rest position. d. All objects have inertia. e. A more massive object has more inertia than a less massive object. f. Fast-moving objects have more inertia than slow-moving objects. g. An object would not have any inertia in a gravity-free environment (if there is such a place). h. Inertia is the tendency of all objects to resist motion and ultimately stop. i. 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. ANS: de 2. Which of the following statements are true of the quantity mass? List all that apply. a. The mass of an object is dependent upon the value of the acceleration of gravity. b. The standard metric unit of mass is the kilogram. c. Mass depends on how much stuff is present in an object. d. The mass of an object is variable and dependent upon its location. e. An object would have more mass on Mount Everest than the same object in the middle of Lake Michigan. f. People in Weight Watcher's are really concerned about their mass (they're mass watchers). g. The mass of an object can be measured in pounds. h. If all other variables are equal, then an object with a greater mass would have a more difficult time accelerating. i. 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. j. The mass of an object is mathematically related to the weight of the object. ANS:: BCFHIJ 3. Which of the following statements are true of the quantity weight? List all that apply. a. The weight of an object is dependent upon the value of the acceleration of gravity. b. Weight refers to a force experienced by an object. c. The weight of an object would be less on the Moon than on the Earth. d. A person could reduce their weight significantly by taking an airplane ride to the top of Mount Everest. e. Two objects of the same mass can weigh differently. f. To gain weight, one must put on more mass. g. The weight of an object can be measured in kilograms. h. The weight of an object is equal to the force of gravity acting upon the object. i. When a chemistry student places a beaker on a balance and determines it to be 84.3 grams, they have weighed the beaker. ANS:: ABCH 4. Which of the following statements are true of an object that experiences balanced forces (or unbalanced forces)? List all that apply. a. If a person is moving to the right, then the forces acting upon it are NOT balanced. b. A balance of forces is demonstrated by an object which is slowing to a stop. c. It would take an unbalanced force to keep an object in motion. d. If an object is moving with a constant speed in a circle, then the forces acting upon the object are balanced. e. If an object is accelerating at a constant rate of acceleration, then the forces acting upon the object are balanced. f. It is NOT possible for just three forces to be acting upon an object and they still balance each other. g. A free-falling object experiences a balance of forces. h. Balanced forces cause stationary objects to remain at rest and moving objects to come to rest. i. Unbalanced forces cause objects to move. ANS: I 5. Consider Newton's first law of motion to determine which of the following statements are true? List all that apply. a. Newton's first law of motion is applicable to both moving and nonmoving objects. b. If a football is moving upwards and rightwards towards the peak of its trajectory, then there are both rightwards and upwards forces acting upon it. c. It would take an unbalanced force to keep an object in motion. d. If an object is at rest, then there are no forces acting upon the object. e. It would take an unbalanced force to keep an object in motion at a constant velocity. f. It is the natural tendency of all objects to eventually come to a rest position. g. A pendulum bob is set into its usual back-and-forth periodic motion. After some time (perhaps 10 minutes), the pendulum bob comes to a rest position. This is best explained by the idea of inertia - all objects eventually resist motion. h. If a 3-kg rock is thrown at a speed of 2 m/s in a gravity-free environment (presuming one could be found), then an unbalanced force of 6 N would be required to keep the rock moving at a constant speed. i. It would take an unbalanced force to cause an object to accelerate from rest. ANS: AI Attached File ( Number of downloads: 5319 ) ![]() |
