Question

ferent For 25b. what change could be made in the setup in diagram 1 to increase the amount of force necessary to move the block of wood? 25c. explain why the round pencils in diagram 2 decrease the amount of force necessary to move the block of wood. Base your answers to questions 26a and 26b on the diagram below and on your knowledge of science. The diagram shows a set of materials that a science teacher used to demonstrate motion. The rubber band has been stretched with a string that has been tied to the nail. A weight is resting on the platform. The platform is resting on several round pencils on a tabletop.

On the diagram above, draw an arrow to represent the direction the wooden platform will move when the lit match burns through the string and the weight is propelled from the platform. 26b, the table below lists four changes to the materials in the diagram. Will the changes cause the distance the wooden platform moves to decrease, increase, or remain the same? For each change in the left column, circle your answer in the right column.
