Washers/Elevator Lab

Procedure
For the elevator portion, we placed a scale on the elevator floor and measured the difference in scale readings when someone stood on it going up to going down. Using the change in mass and time we calculated acceleration. For the washers lab, we set up a pully system with a weight on one side and a counterweight on the other to measure force. We weighed it a t rest, then at constant velocity and then when it was accelerating and recorded our findings

Questions
1. The reading of the scale was less than the actual weight of the mass when the scale was decelerating and was greater when the scale was accelerating because gravity pushes things down when the object accelerates upwards therefore reading a higher counterforce. When the weight is going down, it is going with gravity and thus experiencing less weight that normal
2. Newton's second law of motion states that the acceleration of a n object is directly proportional to the net force acting on it, or F = ma. So if someone pushes something with more mass, more force is required to get it to move with the same accelerating versus something that weighs less. Like a full shopping cart is harder t push than an empty. And a empty box is easier to push that a full one
3. Because there is no air resistance in space, both the feather and the rock will fall according to the moon's gravity. So they will both hit the surface at the same exact time since gravity is the only force acting on it.
