Motion and Forces
Introduction
What was the purpose of the experiment?
Type your answer here: The purpose of this experiment
What were the independent, dependent, and control variables in your investigation? Describe the variables for each part of the experiment.
Type your answer here: The force is independent, the dependent is the time and the constant is the mass.
Write a hypothesis based on observations and scientific principles.

Experimental Methods
What tools did you use to collect your data?
Type your answer here: in the simulation a timer,a rocket ship, force newtons, different mass.
Write your procedure. List each step so that another student could follow the procedure and repeat your experiment.

Conclusions
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:
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: Mass c was the greatest
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.
Type your answer here: The 1 N block at rest will remain at rest unless external force greater than 1 N acts on it. The 1 N block with 2 N force applied in one horizontal direction, will move in the direction of the 2 N force.
