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
  1. 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
