Pls all of them. I have little time
KU TI COM APP 6. a bicep curl is an example of.. PSK4U Unit 4 Test a) a first class leaver b) a second class leaver Biomechanics and Motor 20 c) a third class leaver Development d) none of the above Instructions: Look over the whole test before beginning. There are 4 parts to this test. 7. when a leaver has a high mechanical advantage, that means For multiple choice, choose the answer that best fits. For written answers, make sure a) a lever's effort arm is shorter than its load arm you write enough to receive full marks. For example, if the question is out of 3 marks, b) a lever's effort arm is longer than its load arm then make sure you write at least 3 correct ideas. Good luck! c) a lever's effort arm is the same as its load arm d) a lever's effort arm is on top of the load arm Part A - Knowledge and Understanding [20 marks] 8. The center of gravity is 1. a force is... a) an imaginary point in the middle of an object that does not move a) a change in the motion of the object when it is near an moving object b) an imaginary point in at the top of an object that does not move b) a push or pull that changes the motion of an object c) energy that is generated when an object makes contact with something else c) an imaginary point at the bottom of an object which body weight is evenly distributed d) energy that is pulling us towards the ground d) an imaginary point around which body weight is evenly distributed. 2. motion is created by 9. static balance is the ability to ... a) energy that is released from a person into an object a) control the body while the body is stationary b) the action of pushing or pulling something b) maintain the body in some fixed posture c) the action of forces c) maintain postural stability and orientation with centre of mass d) none of the above d) all of the above 3. when all particles of the human body is traveling in the same direction at the same 10. dynamic balance is the ability to... time, this is known as... a) control the body during motion a) linear motion b) transfer the vertical projection of the centre of gravity around the base of b) rotary motion support c) general motion c) maintain postural stability and orientation while body parts are moving d) curvilinear motion d) all of the above 4. when the trajectories of individual particles of the body are curved, although the 11. the metabolic challenge to maintain powerful and prolonged skeletal muscle orientation of the body in space does not change, this is known as contractions triggers a broad range of biochemical responses in the body is known as a) linear motion a) Physophysical load-response pathway b) rotary motion b) Physiological load-response pathway c) rectilinear motion c) Biophysical load-response pathway d) curvilinear motion d) Biomechanical load-response pathway 5. walking and riding a bike is an example of 12. patterns that allow the body to be coordinated in those simple, basic movement patterns are called a) linear motion a) basic movement patterns b) rotary motion b) fundamental movement patterns c) general motion c) complex movement patterns d) rectilinear motion d) simple movement patterns
