Kinesiology 430 – Lab QuizzesQuiz #1 – Biomechanics Lab Instrumentation1) While there are several methods that can be used to collect kinematic data during human movement, camera systems are the most widely used.a. Trueb. False2) Kinetic data are typically collected using a:a. Motion capture systemb. Force transducerc. Goniometer3) For collecting kinematic data, reflective markers are frequently placed on the surface of the skin overlying bony landmarks. Why is this not ideal?a. Because the adhesive is so strong, the markers will never come offb. Because skin is reflective, which will cause errors during data collectionc. Because the skin and underlying tissue move relative to the bones4) The cameras used in the UMass biomechanics laboratory are of what type:a. Analogb. Digitalc. Nikon5) The force platform in the UMass biomechanics laboratory is a:a. Strain gauge platformb. Bathroom scalec. Piezoelectric force sensorQuiz #2Quiz #3 – Projectile Motion1) Which characteristic of a projectile can be manipulated at the instant it is released into flight?a. Weight of the objectb. Angle of releasec. Wind resistance2) If we assume air resistance is negligible, both the horizontal and the vertical components of the motion of the projectile represent:a. Uniformly accelerated motionb. Only vertical motionc. Constant velocity motion3) The horizontal velocity at the end of a projectile’s flight is ____________ the horizontal velocity at the beginning of its flight:a. Greater thanb. Less thanc. Equal to4) In Part 1 of this lab, you will be examining the effects of increases in speed by manipulating what variable?a. Rubber band strengthb. Rubber band lengthc. Cannon height5) For a projectile, gravity affects _________ motion only:a. Resultantb. Horizontalc. VerticalQuiz #4 – Angular Kinematics1) Goniometers measurea. Lengthsb. Anglesc. Temperature2) For this lab, we will use the electro-goniometer to measure:a. Shoulder joint anglesb. Thumb joint anglesc. Knee joint angles3) The voltage signal from the electro-goniometer is proportional to the _________ (or change in shape) of the wire.a. Stressb. Forcec.
