Physics

1. Dear Lord and Father of all, Thank you for
today. Thank you for ways in which you
provide for us all. For Your protection and
love we thank you. Help us to focus our
hearts and minds now on what we are about
to learn. Inspire us by Your Holy Spirit as we
listen and write. Guide us by your eternal
light as we discover more about the world
around us. We ask all this in the name of our
Lord. Amen.

2. FORCE and
MOTION
BALANCE AND UNBALANCE FORCE

3. Directions: Identify
the following
situation if there is
motion.

4. THERE IS MOTION

5. THERE IS NO MOTION

6. THERE IS NO MOTION

7. THERE IS MOTION

8. THERE IS MOTION

9. When dealing with
motion one factors that
can affect it is FORCE.

10. FORCE???

11. Force therefore can
make objects move,
move faster, stop, or
change their direction
of motion.

12. BALANCE AND
UNBALANCE
FORCE

14. 1. Equal forces acting in opposite
directions in the same line
cancel each other and are
described as being in BALANCE.
2. The movement of objects is
changed if the forces acting on
them are UNBALANCE.

15. LETS TRY!
DIRECTION:COMPUTE THE
NETFORCE AND IDENTIFY
THERE IS BALANCE OR
FORCE.

16. 1. A boy and a girl are
pulling a heavy crate at
the same time with 10
units of force each.
What is the net force
acting on the object?

17. 2. What if the boy and the girl
pull the heavy crate at the
same time in opposite
directions with 10 units and 5
units of force respectively,
what will be the net force on
the object? Will the object
move? To what direction will it
move?

18. 3. Suppose another girl
pulls the heavy crate in
with 5 units of force in the
same direction as the girl,
what will be the net force
that will act on the object?
Will the object move?
