What effect would placing the block on a rougher surface (such as sandpaper) have on the friction? G. Answer questions 7 - 9 page 273. Read 270-272 to find answers. 101 Science Notebook Layout GET WORKSHEETS FROM MY ASSIGNMENTS PAGE Mrs. Aguirre’s Webpage: http://www.quia.com/profiles/caguirre CONCLUSIONS How did changing force affect acceleration? F= ma lab worksheet 4/14/11 More force on an object causes acceleration to speed up. For example, with one washer the cart was slower but with 5 washers the cart accelerated faster. In your answer be sure to: A) Use pictures B) Give examples C) Use as much detail as you can QuickTime™ and a TIFF (LZW) decompressor are needed to see this picture. How did changing the mass affect acceleration? Increasing the mass of an object causes the acceleration to slow down. For example, with one book the speed was the fastest but with four books the speed was the slowest. 102 103 Science Notebook Layout GET WORKSHEETS FROM MY ASSIGNMENTS PAGE Mrs. Aguirre’s Webpage: http://www.quia.com/profiles/caguirre Net Forces Notes P 276-280 1.
