Lab 5 – NEWTON’S SECOND LAW

PRELAB QUESTIONS

1) Explain how we will use the Logger Pro force probe in this lab. What does it mean to “zero” the force probe?

2) Identify all of the forces acting on the falling mass and rolling cart.

3) Compare the tension in the string while at rest versus when it is moving. Are they different? The same? Why?

4) What is a F-statistic and what does it tell you?

5) If the measured force on the cart is a constant 1.2N, and the cart mass is 900grams, what will the slope of the velocity/time graph be?

the answers for 1 , 3 , 4 are only can be done by using the equipement only.

so remaining are..

2 )

using F = m a

so the given force if increase then the mass acceleration will be decreases.

Here in the case of motion under gravity acceleration is independent of mass.

5 )

using F = ma

a = F/m

a = 1.2 / 0.9

a = 1.3 m/s2

slope of the velocity/time graph is also dv/dt = a = 1.3 m/s2
