this week in science we continued our learning on force and force diagrams. over the weeks we have been getting different scenarios like the one that we got at the end of the week with the girl in the elevator. basicly this was a girl on and elevator and she had a scale and when the elevator went down she lost weight and when the elevator went up she gained weight. so after discusing this we decided that she is losing weight because she is going with the elevator making there less force on the scale. but when the elevator is going up she is applying extra force on the scale making the number of nutiens increase.
