Question

TRUE/FALSE (3 Points Each. Write the word "True" or "False", not the letter "T" or "F". I will construct 10 True/False questions by pulling ideas directly from the set of conceptual questions that can be found at the end of each chapter. What follows are some possible example questions: (1) If you are jogging at a constant velocity then you are not doing any mechanical work. The kinetic energy of a system must be either positive or zero. However, the potential energy of a system can be positive, zero, or negative. (3)An Olympic sprinter accelerates out of the starting blocks in a race. It is appropriate to consider her as the only component in a closed, isolated system. 4)Afunctioning clock is mounted on the wall in front of you. The angular velocity vector is pointing out of the wall toward you The total angular momentum of a particle does not depend on there being any kind of reference point from which to measure. Other conceptual question on topics such as forces, conservation of energy and momentum, angular kinematics, work-energy, etc.

Answer 1

(1) False because if you are moving then there is change in kinetic energy so there must be some mechanical work.

(2) True.

(3)false

(4)true

(5)false

(6)
