Concepts (20 points total). Choose the BEST answer Multiple Choice (5 points/each) 1. If an object is subjected to an unbalanced force, ther a) wl accelerate. b) its kinetic energy will change. c) its momentum will change. d) all of the above e) none of the above 2. An object will slide if a) the friction force is less than the normal force b) the friction force is less than the tangential force c) the friction force is greater than the normal force d) the friction force is greater than the tangential force e) none of the above True or False (2 points/each) . T/F Dynamics is concerned with bodies that have accelerated motion 4. T/F Kinetics is a study of the geometry of the motion 5. T/F Kinematics is a study of the forces that cause the motion. 6. T/F Rectilinear kinematics refers to straight-line motion. 7. T/F Mas is aproperty of mater hat provides a quantiaive measure of is resistanc toa change in velocity.

Explanation / Answer

1)correct option is (e).This is because the body will accelerate and hence velocity will change which will result in change in momentum and kinetic energy

2)Correct option is (b) . Sliding happens when tangential force exceeds friction force

3) T

F . Kinetics is study of forces that cause motion

F. Kinematics is the study of the describing movement or geometry of motion

T
