Conceptual Physics Practice Test Questions and Answers Speed - Answer-How fast an object moves; the distance traveled per unit of time. Instantaneous speed - Answer-The speed at any instant. Average speed - Answer-The total distance traveled divided by the time of travel. Velocity - Answer-An object's speed and direction of motion. Vector quantity - Answer-A quantity that has both magnitude and direction. Scalar quantity - Answer-A quantity that has only a magnitude, not a dir...

Kinetic Energy and Jump Height Correct Answer-The relationship between flight height yflight and takeoff velocity vtake-off can be obtained by applying the law of conservation of mechanical energy to the flight phase of the jump. The mechanical energy (E) of the jumper is the sum of the kinetic energy (KE = ½mv2) and gravitational potential energy (PE = mgy). In vertical jumping the effect of air resistance is negligible, and so in the flight phase the jumper can be considered as a projectile i...

Straighterline PHY 250 Exam Questions and Answers - Latest 2023/2024 (GRADED) Would an object precess faster if it had more angular momentum? Select one: a. Yes, because the change in angular momentum depends on its magnitude b. Yes, because the energy of the system has increased c. No, because precession only depends on the amount of applied gravitational force d. No, because the angular velocity of precession is inversely proportional to the magnitude of the gyroscope’s angular momentu...
