This document discusses forces like gravity and their effects on motion, providing examples like how apples fall from trees due to gravity. It asks the student if they have seen or felt the effects of gravity, and defines force as an effect that can change a body's state. Examples of forces are also given, such as those that power trains, ships, and fans through motion.

1. Dear student , Are you interested in apple !

2. So .. Do you know that apples had shared in
physics laws !

3. Do you know the story of that !

4. The fall of apple towards the ground is a kind of
force called : Force gravity 

5. Okay .. According to that force .. Have we seen it or
felt the effect of it ?

8. Dear student , Are you interested in football ?

11. So , What is Force ?
It is an effect that may change the state of
the body.

12. The measuring unit of force is Newton

13. Do you like rope – game ?

14. So , Let’s play it 

15. Conclusion
Motion increases by the increase of force.

16. Name these forces

17. The effort of force on motion
Force causes the motion and lifting of an object

18. Technological applications depend on force in motion
Train
Blinder
Ship
Fan

19. Technological applications using force to lift heavy
objects.
Lift Escalator
Fishing rod
