9. Which law of motion does this demonstrate? ¿Qué ley demuestra esto?

10. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? First Law (Law of Inertia)! Objects in motion, stay in motion unless acted upon by an unbalanced force.

11. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? Which law of motion does this demonstrate? Force= 20 N mass= 7 kg

12. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? Which law of motion does this demonstrate? Force= 20 N mass= 7 kg Second Law (Law of Force and Acceleration)! Using the mass of the object, and the force applied, we can calculate how fast the object accelerated.

13. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? Small mass Same force Large mass

14. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? Second Law (Law of Force and Acceleration)! More Force is needed to accelerate objects with more mass at a higher rate. Same force Small mass, large acceleration Large mass, small acceleration

15. Which law of motion does this demonstrate? ¿Qué ley demuestra esto?

16. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? First Law (Law of Inertia)! The rider and bike were in motion, an unbalanced force of the wall stopped the bike but the rider continued moving at the same speed and same direction.

17. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? With no outside forces, this object will NOT move With no outside forces, this object will NOT stop moving

18. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? With no outside forces, this object will NOT move With no outside forces, this object will NOT stop moving First Law (Law of Inertia)! Objects will continue doing what they are doing if no outside forces are applied!

19. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? Why does the Earth keep spinning?

20. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? Why does the Earth keep spinning? First Law (Law of Inertia)! Objects will continue doing what they are doing if no outside forces are applied The planets will continue orbiting the sun!

21. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? More force, more acceleration

22. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? More force, more acceleration Second Law (Law of Force & Acceleration) ! Acceleration is dependent the mass of the object and the force applied.

23. Which law of motion does this demonstrate? ¿Qué ley demuestra esto?

24. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? First Law (Law of Inertia) ! The more mass, the harder to change its motion.

25. Which law of motion does this demonstrate? ¿Qué ley demuestra esto?

26. Which law of motion does this demonstrate? ¿Qué ley demuestra esto? Second Law (Law of Force & Acceleration) ! Objects with less mass, accelerate faster than heavier objects if same force is applied.

27. Essential Question: How does Newton’s third law of motion explain everyday activities? TEKS:8.6 C Investigate and describe applications of Newton's law of inertia, law of force and acceleration and law of action-reaction such in vehicle restraints, sports activities, amusement park rides, and rocket launches. I CAN STATEMENT: • I CAN identify and explain Newton’s Third Law of Motion (Law of Force and Acceleration) • PUEDO identificar y explicar la Tercera Ley de Movimiento de Newton (Ley de Fuerza y ​​Aceleración)
