Lab Report Motion and Forces It’s time to complete your Lab Report. Save the lab to your computer with the correct unit number, lab name, and your name at the end of the file name (e. g., U4_ Lab_MotionAndForces_Alice_Jones. doc). Introduction 1. What was the purpose of the experiment? Type your answer here: 2. What were the independent, dependent, and control variables in your investigation? Describe the variables for each part of the experiment. Type your answer here: 3. Write a hypothesis based on observations and scientific principles. Type your answer here: Experimental Methods 1. What tools did you use to collect your data? Type your answer here: 2. Write your procedure. List each step so that another student could follow the procedure and repeat your experiment. Type your answer here: Data and Observations 1. Record your observations. Type your answer here: Conclusions 1. What conclusions can you draw about how the sum of forces acting on an object affect its motion? Write an evidence-based claim. Type your answer here: 2. Which mass, A, B, or C, was the greatest? Use the observations from your experiment and your knowledge of Newton’s laws of motion to write an evidence-based claim. Type your answer here: 3. Make a model that shows the forces acting on two blocks on a flat, frictionless surface: a. A 1 N block at rest b. A 1 N block with 2 N of force applied in one horizontal direction Include arrows to represent the forces and labels to indicate the magnitude of each force. Use your model to compare and explain the motion of each block. Type your answer here:
