Goals
The goals of 6.11 was to help us figure out how force affects acceleration.
The goals of 6.12 was to help us figure out the relationship between acceleration and mass.
LAB 6.11 DATA: ACCELERATION VS FORCE
When I applied 1 unit force to the cart the acceleration was 10 centimeters per second per second.
When I applied 2 unit force to the cart the acceleration was 17.5 centimeters per second per second.
When I applied 3 unit force to the cart the acceleration was 25 centimeters per second per second.
LAB 6.1 CLAIM
The more force you put on a object the faster the acceleration is going to be.
LAB 6.12 DATA: ACCELERATION VS MASS
when the mass of the cart was 500g, the acceleration was 10 centimeters per second per second.
when the mass of the cart was 1000g, the acceleration was 7.5 centimeters per second per second.
when the mass of the cart was 1500g, the acceleration was 5 centimeters per second per second.
LAB 6.12 CLAIM
The bigger the mass the slower the acceleration is going to be.
MAKING AN EQUATION
Force is one part of the equation for acceleration. From my lab, I discovered that force multiplies acceleration.
Mass is one part of the equation for acceleration. From my lab, I discovered that mass divides from acceleration.
Therefore, acceleration = force / mass
CHECK YOUR EQUATION
If force = 1, and mass =1, acceleration equals to 1
If force = 2, and mass =1, acceleration equals to 2
If force = 1, and mass =2, acceleration equals to 1/2
Yes, my equation works.
