Objectives
·
Understand and define
force
·
Calculate an object’s
force
·
State and apply
Newton’s First and Second Law of Motion
1. What is force? Give three examples of a force being exerted.
A force is
a push or pull upon an object resulting from the object’s interaction with
another object.
Examples:
pushing a desk across the room, gravity, pulling a door open
2. What is the difference between an unbalanced and balanced
force?
A balanced
force does not cause an object to move.
An unbalanced force will cause an object to move.
3. Write Newton’s First Law of Motion.
An
object at rest tends to stay at rest, and an object in motion tends to stay in
motion with the same speed and in the same direction unless acted upon by an
unbalanced force.
4. Write Newton’s Second Law of Motion
The
acceleration of an object as produced by a net force is directly proportional
to the magnitude of the net force, in the same direction as the net force, and
inversely proportional to the mass of the object.
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 Law.
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?
Calculate the force
exerted at each acceleration using 2500 kg as your mass.
