2. OBJECTIVES
1. explain the motion of an object
through the concept of force.
2. Identify the forces acting on objects at
rest
3. Relate the principles behind how things
move the way they do in real-life
situation.

3. MAGNITUDE
•Refers to the size or strength of the force
applied to an object. It is commonly
expressed in Newton (N)
DIRECTION
•Represented by an arrow.

4. •Object can be moved by pushing or pulling. In
physics, this push and pull is referred to as Force
(F).
•In order to make the object move, speed up, slow
down, stop, or change its direction, it has to be
pushed or pulled. The motion of an object can be
changed if we apply FORCE on it.
•Magnitude refers to the size or strength of the
force. It is commonly expressed in Newton (N).

5. • Magnitude refers to the size or strength of the force. It is commonly
expressed in Newton (N).

8. BALANCED FORCES
•The same
magnitude
•In an
opposite
direction
•It lies on the same line
of action

9. SHORT ESSAY
•What is force? How does force affects the
motion of an object?
•What are the conditions for an object to stay
at rest, to keep moving at constant velocity, or
to move with increasing velocity?
