 Which of the following is NOT considered to be one of the “fundamental forces”? C. Which of the following forces is NOT associated with the “electromagnetic force”? B. When analyzing dynamics problems, free-body diagrams C. An object is pushed horizontally at a constant velocity. What can correctly be said about the forces acting on the object? B. Which of the following is NOT an example of “inertia”? E. An object’s “weight” E. With respect to Newton’s third law, the action and reaction forces B. According to Newton’s third law, when you walk across a floor, the force that propels you forward is D. A 4.0-kg object, A, and a 2.0-kg object, B, are connected with a rope. A force is applied to another rope attached to the 2.0-kg object that pulls both A and B along a horizontal surface. Which of the following statements is true? E. An object sits at rest on a ramp. As the angle of inclination of the ramp increases, the object suddenly begins to slide. Which of the following explanations best accounts for the object’s movement? A. Streamlining is a technique that designers use to A. Which of the following does NOT utilize Bernoulli’s principle? E. Which of the following would be considered an “inertial” frame of reference? A. Which of the following frames of reference (inertial or noninertial) should NOT be grouped with the rest? B. Imagine that you are travelling in a train and you have a drink sitting on the dining table in front of you. The train suddenly stops and the drink ends up in your lap. What force acting on the drink is responsible for its sudden motion? E. The law of inertia holds A. For an object travelling with “uniform circular motion,” D. For an object travelling with “uniform circular motion,” its acceleration is D. The reason that curves on roads are often banked is because E. A rock is tied to the end of a string and whirled around in a circle that describes a vertical plane. At which position is the tension in the string the least? C. Imagine you are a passenger upside-down at the top of a vertical looping roller coaster. The centripetal force acting on you at this position E. For objects travelling with uniform circular motion, the centrifugal force they experience E. The person responsible for determining the value of the universal gravitational constant is D. The orbital radius of a satellite circling the Earth A. Astronauts on board an orbiting space station appear to be “floating” because D. To produce an artificial gravity on board a space station D.
