      dividing by 2 is the same as multiplying the same thing by 1/2 for example 10/2=5 and 10*.5=5. so he just divides by 2 instead of multiplying by 1/2 because it is the same.

    So, if we could measure the REAL kinetic energy of a 1 kilo block of metal that sits still on a table, minus rotation of earth, minus revolving around the sun, minus revolving around center of the galaxy, we would know how fast were moving away from the center of the universe?

      so using the formula m multiply v square divided by 2: 750 multiply 55 square (you press the square feet symbol on your calculator) which should equal 2'268750 and then divide it by two. Which your final should be 1,134,375 J

      @Jonathan-bu7pl 6 років тому +4

      When dealing with kinetic energy, you have to round it with scientific notation, so basically getting it to one decimal place and multiplying it by 10 to the power of _____ to get to a rounded number of the original
      1.1x 10 to the power of 6 (1000000) = 1100000 which is the rounded number of 1,134,375
