CHAPTER 1 1. Suitable ruler to use in laboeratory Suggestion Explanation Smallest size scale 0.1 cm More accurate High accuracy Less error in measurement High consistency Low relatie eiiatons Plastc material Aioi parallax error Thin thickness Aioi parallax error CHAPTER 2 2. Explain the suitability feature of arm exercise equipment. Suggestion Explanation Spring ma e of steel Can withstan higher force Two // more spring arrange in parallel The spring system is stier Spring with tcker wire Wire will not easily break Smaller iameter coil of spring The smaller the iameter coil less elastc the spring, so the arm exercise woul not so har Choose large force constant spring Will make strong spring, the spring will stier an not broken easily suggestion Explanation Use tght an light suit Less air fracton Use spikes shoes Better grip support while running an preient slippery Use thicker mattress Increase tme impact , re uce impulsiie force . preient back injury The athlete haie to sprint before jump Can increase kinetc energy Athlete haie to ben the bo y uring fall Increase the tme impact , re uce impulsiie force 3. Suggest the suitable cloth , equipment an techniques to improie high jumper athlete an their safety . 4. Explain the characteristc of spring to make baby's cra le. Suggestion Explanation Choose large force constant spring Will make strong spring, the spring will stier an not broken easily. Choose large iameter of wire The larger iameter the stier the spring is.
