1.Explain in your own words about how gravitational force works between two isolated objects and use this understanding to explain how a satellite can remain at the same place above the surface of the rotating earth.2. In an experiment to study Hooke’s law for solid material, the extension for three different wires A, B and C were obtained for various applied force as shown in TABLE Q3b.a.Consider all the extensions were within the elastic limit. Draw graph of extension against force for each wire and use it to identify which of the wires requires the most work done to extend to 3.8 mm.b.Determine the elastic modulus of each wire and arrange them according to their stiffnesses.

Learning Goal: To understand Newton's law of universal gravitation and be able to apply it in two-object situations and (collinear) three-object situations; to distinguish between the use of G and g. In the late 1600s, Isaac Newton proposed a rule to quantify the attractive force known as gravity between objects that have mass, such as those shown in the figure. (Figure 1) Newton's law of universal gravitation describes the magnitude of the attractive gravitational force Fg between two objects with masses m₁ and m₂ as F₁ = G ( m₂ where r is the distance between the centers of the two objects and G is the gravitational constant. Figure m1m2 The gravitational force is attractive, so in the figure it pulls to the right on m₁ (toward m₂) and toward the left on m2 (toward m₁). The gravitational force acting on m₁ is equal in magnitude to, but exactly opposite in direction from, the gravitational force acting on m2, as required by Newton's third law. The magnitude of both forces is…

You push a box up a ramp (friction between the box and the ramp is not negligible). Call the initial state when you begin to push the box. Call the final state after you have pushed the box up the ramp a distance of 0.5 m and it is moving with a speed of 2 m/s. 1. System: box + ramp2. System: you3. System: box + ramp + Earth4. System: box5. System: box + ramp + Earth + you This question is asking whether or not the energy of the system stays constant or if the energy changes in each one of these situations.

Based on Newton's Action-Reaction law of motion, a tennis racket exerts a force that is equal and opposite to the force the tennis ball exerts on the tennis racket. Does it follow that the impulse the tennis racket exerts on the tennis ball is equal and opposite impulse the tennis ball exerts on the tennis racket? Explain. 2. What role do air bags play in reducing the chances of injury in car accidents? Explain in terms of momentum and impulse. 3. You are on summer vacation with your family and watched children playing with a ball by rolling it down the slide.
