Science

On the topic of Forces and Motion in Science, We learned how to calculate speed, force, distance, and time using different formulas and learned different units.

 Force:  F=ma

              = m(mass) x a(acceleration)

              = n N

     

 Speed:  V= d/t

               = d(distance) / t(time)

               =  n ms-1 ( meter per second)

 Distance: d= v x t

                 = v(velocity)xt(time)

                 = n m

Time: t=d/v 

          =d (distance)/ v(velocity)

 We investigated how fast cars are going on Carmen Road, whether they were speeding or not. 

 

We first used a stopwatch to measure how fast they were going and listed down on my book. We found the average time by adding the time and divided them by 10. Then to find out the m s-1  we divided the time to 50. and added them and divided them by 10 to find out the average m s-1. I didn't finish working out my km hr-1 so I don't have an answer.
