Newtons First Law
- An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
Newtons Second Law
- The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Newtons Third Law
- For every action, there is an equal and opposite reaction.
In this lab, we explore the relationships between force, mass, and acceleration using an Atwood's Machine.
(Due to an absence in class, I used a Pivot interactive activity to simulate the lab and produce results.)
Firstly - We were asked to graph an acceleration vs total force graph. For this, I kept the system mass constant so that the only variable is the weights.
Secondly - I used the equation x = Vi*t +1/2*a*t^2 to calculate the acceleration of each test run and plug that into my data chart.
Thirdly - I calculated the total force by taking the mass in grams and multiply it by 0.0098 N/g and used that result as my total force in my data chart.
Secondly - I used the equation x = Vi*t +1/2*a*t^2 to calculate the acceleration of each test run and plug that into my data chart.
Thirdly - I calculated the total force by taking the mass in grams and multiply it by 0.0098 N/g and used that result as my total force in my data chart.
The r = 0.988 |
Acceleration = 193 * total force - 0.504

Secondly - I used the equation, x = Vi*t +1/2*a*t^2, to calculate acceleration of each test run and plug it into my data chart. The hanging mass was held constant during these trials.
