Objectives

·        Understand and define force

·        Calculate an object’s force

·        State and apply Newton’s First and Second Laws of Motion

 

 

A. Pre-lab Questions

1.      What is force? Give three examples of a force being exerted.

 

 

 

2.      What is the difference between an unbalanced and balanced force?

 

 

 

3.      Write Newton’s First Law of Motion.

 

 

 

4.      Write Newton’s Second Law of Motion

 

 

 

 

 

B. Group Lab

In the last lab you watched two movie clips to determine an object’s acceleration.  You will use that data in this lab and apply it to Newton’s First and Second Laws.

 

Newton’s First Law of Motion

 

Looking at your data from the last class, write down the forces exerted on the object.

 

 

 

 

How did these forces affect the object’s acceleration?

 

 

 

 

Newton’s Second Law of Motion

 

Calculate the force exerted at each acceleration using 2500 kg as your mass.
