Now, let's consider a second case - the case of constant acceleration. First, try to make the block accelerate at a constant rate with your hand (make sure it doesn't go flying off the end of the table!). Let each group member take a turn. c. Again, think about all of the forces acting on the block. Discuss amongst your group how the forces should relate to each other, in order to produce a constant acceleration. Draw free body diagrams of the forces acting on the block at two successive times, indicating the magnitude and direction of each force. d. Explain your thought process in deciding what forces are acting on the block, and how big they should be at each time. Again, do all of your group members agree with this? If you do not all agree, what are the different ideas being considered, and why? block block t1 t2
