Place the board in front of you with the four strips arranged left to right. Place the supplied container on one strip and the mass in the container.
Place the board in front of you with the four strips arranged left to right. Place the supplied container on one strip and the mass in the container.
Now attach the spring scale to the mass so you can read the scale.
Watch the scale as you pull the mass and container up the board.
Record the Newtons required to start the mass moving across the first strip.
