3.  DEFINITION
In science, force, usually means either a push or a
pull. Something that cause an object moves, changes its
speed, direction and shape.
You cannot see a force but you can see what it does. You
can also feel the effect of a force on your body.

4.  A force can make an object move.
 A force can make a moving object stop.
 A force can change the direction of a moving object.

5.  A force can change the shape of an object.
 A force can change the speed of a moving object.
 A force can be measured with a Newton spring balance. The
S.I unit for measuring force is the Newton (symbol N).

6. Types Of Forces
 Air Resistance Force
 Applied Force
 Spring Force
 Frictional Force
 Gravitational Force
 Electrical Force
 Normal Force
 Magnetic Force

7. Air Resistance Force
 Air Resistance Force is the Force of air pushing
against a moving object.

12. Applied Force
 Applied Force is when a living creature puts pressure
on a object.

13. Spring Force
 Spring Force is when an object is push togther then
when pressures taken away it pops back to its normal
self.

14. Frictional Force
 Frictional Force is present everywhere in our daily
life. simply impossible to reduce it completely.

15. Gravitational Force
 The Gravitational Force is a force that attract any
objects with mass.

16. Electrical Force
 Electrical Force is the attractive or repulsive
interaction between any two charged objects.

17. Normal Force
 Normal Force is the support force exterted upon an
object which is contact with another stable object.

18. Magnetic Force
 Magnetic Force is attraction or repulsion that arises
between electrically charged particles because of their
motion.
