The objects whose average speed you're to measure (in m/s) are A water drop rolling down a windowpane A marble rolling across a table after rolling down a ramp A ball pitched as fast as you can across a yard or field A ball, dropped from rest from a height of 2 m (or higher, if safe) Yourself, walking at your usual pace a distance of 10 m Yourself, walking at your usual pace a distance of 20 m Prediction Look over the list of average speeds to be measured, and record your prediction 5pred for each of them in m/s. For some, it may be easier to make predictions in units of cm/s initially, then convert to m/s. Which of the objects, if any, do you think will move with a constant speed from start line to finish line?1 Why? How do you think you'll be able to tell?
