An object falls from rest on a high tower and takes 5.0 s to hit the ground.

calculate the object’s position from the top of the tower at 1.0 s intervals.

what would the position-time graph for the object’s motion look like? in your response, show what you are given, the equation that you used, any algebra required, a table of data, and your graph.

12 drag each label to the correct category. decide whether each statement describes mass or weight. measured in newtons measured in kilograms does not change when gravity changes === a gravitational force changes when gravity changes the amount of matter in something mass weight

Ten students stand in a circle and are told to make a transverse wave. what best describes the motion of the students? each student bumps the shoulder of his or her neighbor. at the exact time, all students take a step to the right. the students skip clockwise, going in a circular motion. one at a time, each student lifts his or her hands up and then down.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?
