FORCE AND MOTION
OBJECTIVES
•Define Force
•Identify the different types of Force
•Appreciate the value of force in our dayto-day living
ARISTOTLE, GALILEO,
AND NEWTON
ARISTOTLE
Aristotle’s view of motion is “it
requires a force to make an object
move in an unnatural manner” – or
more simply, “motion requires force”
GALILEO
The natural tendency of an object
was to continue moving at constant
rate in a straight line, and that no
force was needed to sustain its
motion.
NEWTON
Galileo’s idea of motion was later
proven true by the experiments that
Isaac Newton conducted.
FORCE
– push or pull acting upon an
object as a result of its interaction
with another object.
– any influence capable of
producing a change in the state of
motion of an object
What can force do to motion?
1.Force can make an object move
starting from a rest position.
2.Force can make a moving object stop.
3.Force can change the direction of a
moving object.
Force is a quantity which is measured
using a standard metric unit known as
newton (N).
Balanced and Unbalanced Force
•A force may not always cause an
object to move, especially if there is
more than one force present.
Balanced and Unbalanced Force
•Resultant Force (net force) – the
single force that acts and causes a
change in the state of motion of an
object. It is the vector sum of all the
forces acting on an object.

TYPES OF FORCES
1. The students will be grouped into four. The group will create a
concept map that shows the types of force using a manila
paper.
2. Each group will be given 2 types of force and they will give
examples or applications in our daily life
