Understanding Motion and Forces Lab Report
Introduction
1. What was the purpose of the experiment?
The purpose of this experiment was to observe how motion occurs and how forces affect the motion of an object.
2. What were the independent, dependent, and control variables in your investigation? Describe the variables for each part of the experiment.
The independent variable was the force applied to the object. The dependent variable was the motion of the object. The control variable was the surface on which the object was placed.
3. Write a hypothesis based on observations and scientific principles.
I hypothesize that increasing the force applied to the object will result in faster motion due to the relationship between force and acceleration outlined in Newton's second law of motion.
Experimental Methods
4. What tools did you use to collect your data?
I used a stopwatch to measure the time taken for the object to move a certain distance after applying different forces.
5. Write your procedure. List each step so that another student could follow the procedure and repeat your experiment.
1. Place the object on a flat, frictionless surface. 2. Apply a force of 1 N to the object in a horizontal direction. 3. Measure the time taken for the object to move a certain distance. 4. Repeat the experiment with forces of 2 N and 3 N.
Data and Observations
6. Record your observations.
Conclusions
7. What conclusions can you draw about how the sum of forces acting on an object affect its motion? Write an evidence-based claim.
The sum of forces acting on an object directly influences its motion. When a greater force is applied, the object accelerates faster, demonstrating the relationship between force and acceleration.
8. 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.
The mass with the greatest acceleration was mass C, as it showed the highest speed when a force was applied, indicating a lower mass compared to A and B.
9. Make a model that shows the forces acting on two blocks on a flat, frictionless surface:
A 1 N block at rest
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.
