26 Chapt. 3 Vectors and Trigonometry 6. The prototype vector in physics (i.e., the one that is usually thought of setting what the standard physical vector properties are) is . One main reason for this is that of the physical vectors, only has extension in ordinary physical space. a) force b) mass c) displacement d) speed e) the electric Feld vector 003 qmult 00222 1 1 4 easy memory: speed 7. Because it is the magnitude of velocity, speed has: a) one angle. b) an angle. c) a direction. d) no direction. e) only negative values. 003 qmult 00230 1 1 4 easy memory: deFnition of acceleration Extra keywords: physci 8. Acceleration is: a) speed. b) velocity. c) the rate of change of velocity with time. It is a SCALAR . d) the rate of change of velocity with time. It is a VECTOR . e) the rate of change of displacement with time. It is a VECTOR . 003 qmult 00232 1 1 3 easy memory: vector uniform circular motion Extra keywords: physci 9. You are going in a circle at a uniform speed (i.e., a constant speed). Is your
