Clyde and marilyn are riding a roller coaster. during which section of the track is their potential energy converted to kinetic energy?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

The slope of a velocity time graph over any interval of time gives the during that interval

What is the measurement of how fast an object moves relative to a reference point?
