Lesson 1: Force, mass, and acceleration

# Apply: force, mass, and acceleration

## Problem

Three teams of students are designing an experiment to study the relationship between the mass of an object and its acceleration due to a force. All three teams are using the variation of an atwood machine shown below.
Team 1 varies the mass of ${M}_{\text{b}}$ and measures the time ${M}_{\text{b}}$ takes to reach the floor for each mass.
Team 2 adds low-friction wheels to ${M}_{\text{a}}$. Then, they vary the mass of ${M}_{\text{b}}$ and measure the time that ${M}_{\text{b}}$ takes to reach the floor for each mass.
Team 3 adds low-friction wheels to ${M}_{\text{a}}$. Then, they measure the time it takes ${M}_{\text{b}}$ to reach the floor.
Which team’s procedure would best determine how force affects a mass’s acceleration?
