Scenario 1
What is the mass of the turtle?
observations: The tension in both strings is equal.
Scenario 2
What is the coefficient of static friction between the block and the ramp?
observations: You can find the angle by measuring 2 of the sides with a meter stick.
Scenario 3
Write an expression for the force of friction between the surface of the balance
and the meter stick. The only unknown in the expression is the coefficient of
static friction.
and the meter stick. The only unknown in the expression is the coefficient of
static friction.
observations: The normal force of the floor is equal to mg.
Scenario 4
What should the spring scale read?
observations: Because the first box is going in the negative direction, and the second is going in the positive, the spring scale will read the mass times gravity.
