A 100 Kinetic and Gravitational Potential Energy A 100 Is work being done in all of the following situation (if not, in which situation is work not done)? Pushing a crate, lifting a crate, holding a crate above your head, A 200 Holding the crate above your head—there is no displacement. A 200 What is a unit of work? A 300 The Joule James Prescott Joule A 300 Is work a scalar or a vector quantity? A 400 It is a vector quantity. It has both magnitude and direction. A 400 If you are carrying a crate from one place to another, are you doing work? A 500 No A 500 What term refers to the energy of motion? B 100 Kinetic Energy B 100 How is energy defined in Physics? B 200 The ability to do work. B 200 What term refers to the sum of kinetic energy and all forms of potential energy? B 300 Mechanical energy B 300 What form of energy is related to an object’s height above a baseline position. B 400 Gravitational potential energy B 400 What energy change occurs as a roller coaster car moves from the top of a hill to some point down the hill? B 500 Potential energy is begin converted to kinetic energy. B 500 How is momentum defined? C 100 Momentum is the product of mass and velocity C 100 What is an impulse? C 200 Impulse is equivalent to a change in momentum. C 200 What is the Conservation of Momentum? C 300 The total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects. C 300 DAILY Please no wagering. DOUBLE C 400 What in conserved during a perfectly elastic collision --momentum, kinetic energy, or both momentum and kinetic energy? C 400 Momentum and kinetic energy are both conserved. C 400 What in conserved during a perfectly inelastic collision --momentum, kinetic energy, or both momentum and kinetic energy? C 500 Momentum is conserved but there is a loss of kinetic energy. C 500 What is another term form tangential velocity? D 100 Circular velocity D 100 What force maintains an object’s motion in a circular path? D 200 Centripetal force D 200 In what direction is centripetal force directed? D 300 Towards the center of a circular path D 300 In what direction is centripetal acceleration directed? D 400 Towards the center of a circular path D 400 Which of the following equations is used to calculate circular velocity, which one is used to calculate centripetal acceleration, and which one is used to calculate centripetal force? D 500 (a) Centripetal acceleration (b) Circular velocity (c) Centripetal force D 500 Which scientist developed the Universal Law of Gravitation? E 100 Sir Isaac Newton E 100 What did Cavendish use to determine G, the constant used in the Gravitation Equation. E 200 He used a torsion balance. The twisting of the wire measures the gravitational attraction between masses. E 200 Is the gravitational force of attraction directly or inversely proportional to the masses. E 300 Directly proportional E 300 Is the gravitational force of attraction directly or inversely proportional to the distance between bodies. E 400 Inversely proportional E 400 Who explained that a planet maintains its orbit around the sun due to a distortion of the fabric of space-time. E 500 Who else but Albert Einstein! E 500 How is power defined? F 100 Power is the rate at which work is done. F 100 Is the period of a vibration directly proportional or inversely proportional to the frequency? F 200 Inversely proportional F 200 What factor influences the period of a pendulum bob on a string, the angle release, the length, or the mass of the bob? F 300 Length F 300 What is the quantity that measures the ability of a force to rotate an object around some axis? F 400 Torque F 400 What is the average position at which the gravitational force acts on the body? F 500 Center of Gravity F 500 The Final Jeopardy Category is: Friction Please record your wager. Click on screen to begin The relative roughness of the two surfaces indicated by the coefficient of static friction of the surfaces (us), is one factor that influences maximum friction force, what is the other major factor. Click on screen to continue The magnitude of the contact force between the object and the surface on which it rests. The larger the contact force (normal force), that harder it is to make the object start sliding. Click on screen to continue Thank You for Playing Jeopardy! Game Designed By C. Harr-MAIT
