- 1- An object is constrained to move inside a vertical ring near the surface of Earth as shown in the picture. Answer the following questions: What are the forces acting on the object b) is the work done by each force zero, positive or negativel SIndicate (with a T of F) whether the statement is true or false. If false, change the underlined word or phrase to make the statement true. A bicycle moving at 5.0 m/s at sea level has more potential energy than a motionless bicycle at the top of a mountain. Mechanical work is calculated by multiplying the magnitude of a force times the amount of time it is applied. The SI unit for work is the joule. One joule is equivalent to 1N: m in SI units 5 tv MacBook ProIf an object is moved a distanced up an inclined plane at an angle of θ with respect to the horizontal, the normal force from the plane on the object is FN=mgcosθ. What is the work done by the normal force during this motion? A) (mgcosθ)d B) (−mgcosθ)d C) 0 D)mgd E)−mgd
