Lesson Package - Forces pg10

Mass of 1 marble = 2.5g

Mass of diamond needed = 53g

Length of original spring = 12cm 


Steps:

Step 1: Place 10 marbles(10 x 2.5g= 25g) inside bag and attach to spring. 

Step 2: Measure extension, y cm , of spring (Total length minus original length of spring).  

Step 3: Using proportion, find the extension that corresponds to actual diamond

              25g → y cm

              53g → (y/25 x 53) cm

Step 4: Replace the marbles with the raw diamond (plasticine)

Step 5: Remove small bits of plasticine until the extension matches the extension made by 53g
