6. Let’s Think! Imagine that you are running very fast when suddenly, someone blocks your path. What do you think will happen?

7. Melcs : Relate impulse and momentum to the collision of objects (e.g., vehicular collision) (9FE-IVb-36) MOMENTUM

8. LEARNING TARGETS: Define momentum. Describe how mass and velocity affects the momentum of the object. Calculate the momentum of the moving objects. Deduce road safety practices.

9. Let’s Explore Group Activities: Crash Course Momentum (Story Reading) Rolling Marble Activity (for velocity) Rolling Marble Activity (for mass) Bouncing Ball Activity Car vs Truck (video watching)

10. Momentum “Mass in motion” The object has momentum if: It has a mass It is moving

11. Mathematically, it is expressed as p – is the momentum of the moving object ( kg ● m /s) m – is the mass of the moving object (kg) v – velocity of the moving object (m/s)  

12. Sample Problem: What is the momentum of 22 kg grocery cart which travels at 1.2 m/s? Solution: p = m x v p = 22 kg x 1.2 m/s p = 26.4 kg ● m /s

13. How does VELOCITY affect the momentum of a moving object? The momentum increases as the velocity increases . Directly proportional

14. How does MASS affect the momentum of a moving object? The momentum increases as the mass increases . Directly proportional

15. Does momentum of an object can be transferred to another object? Yes, the momentum is transferred when one object hits another object. The momentum moves from one object to another.

16. Let’s Apply A large truck and a car are both moving at the same speed. If both of them lose their brakes and crash against a wall, which would suffer greater damage, the truck or the car? Why?

17. Let’s Apply If you were in a car that was out of control and had to choose between hitting a haystack or a concrete wall, which would you choose? Why?

18. Let’s Apply Cars used to be built as rigidly as possible to withstand crashes. Today, though, cars are designed to have “crumple zones” that collapse upon impact. What is the advantage of this new design? Cars used to be built as rigidly as possible to withstand crashes. Today, though, cars are designed to have “crumple zones” that collapse upon impact. What is the advantage of this new design?

19. Let’s Evaluate Answer the following problems. A 5.0 kg ball is launched with a speed of 2.0 m/s. Find the momentum of the ball. (1 point) A 500 kg car is driving at a speed of 4 m/s. Find the momentum of the car. (1 point) Two students are running in a cross-country race. One has a mass of 60 kg, while the other has a mass of 70 kg. If they are both running at a speed of 7 m/s, which has more momentum? Why? (3 points)

20. Let’s Extend Define Impulse and how is it related to momentum.
