Inquiry 2 Force with varied massIntroduction In this inquiry the relationship between oblige and mass was studied. This inquiry presents a question when mass is increased is the force required to move it at a constant velocity increased, and how large ordain the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a 4-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.Materials and MethodsIn the experiment these materials were use in the following ways. A piece of Veneer wood was used as the surface to pull the object over. Placed on top of this was a rectangular wood block weighing 0.148-kg (1.45 N/ 9.80 m/s/s). A string was attached to the wood block and then a loop was made at the end of the string so a northward scale could be attached to determine the force. The block was placed on the Veneer and drug for about 0.6 m at a constant drive to determine the force needed to pull the block at a constant speed. The force was read off of the Newton scale, this was difficult because the scale was in motion pulling the object. To increase the mass weights were placed on the top of the ...
