Purpose : Find relationship between mass & acceleration and force & acceleration
Materials: Carts, Pulley, Weights, Washers
(insert a labeled drawing or picture)
Data:
a. force & acceleration
Total mass of cart + extra mass + 10 washers = _g=
= kg
Average Weight of one washer =
_ N (weight of 10 washers/10)
Trial
Number of washers
Total Fg from washers = mass *gravity
(Newtons)

Graph:
a. Mass vs. Acceleration
b. Force vs. Acceleration
Calculations: Show work
1. Weight of one washer = Weight of 10 washers / 10
2. Force of gravity: Force (gravity) = mass x gravity Gravity = 9.81 N/kg
3. Acceleration = 2 distance / time ^2
Conclusion:
Purpose
Results (What where the relationships between the variables)
