Physics Review Question
What is this question really asking? Explanation by: Jennifer I [ Return to question menu ] Answer 1 INCORRECT. All objects fall to earth at the same rate, graph #1 shows the acceleration of objects with greater mass being higher. return to top Answer 2 INCORRECT Objects with greater mass do not demonstrate less acceleration due to gravity. Acceleration for objects near the eath's surface is always 9.8m/s2 down return to top Answer 3 INCORRECT All objects have an acceleration of 9.8m/s2 down when dropped near the earth's surface. The value is not determined by the mass of the object. A graph such as graph #3 would occur if air friction was a part of the question. return to top Answer 4 CORRECT The acceleration of all falling objects on earth is 9.8m/s2 down, a constant value as shown in a flat graph. return to top What's this question really asking? Ignoring air friction, how are mass and acceleration of falling objects related? return to top |
