- 9. IMPULSE • Impulse isthe change in momentum caused by a force applied over time. • Most often, mass doesn’t change, so velocity changes, and this is acceleration. • A change in momentum is known as an impulse. • Formula: Impulse = Force × Time (I = F × t) Impulse = Δp DEFINITION: 6 CCBHS | 2025
- 10. FORMULA 7 Formula: Impulse =Force × Time (I = F × t) Where; I = Force x time (N • s) F = force (N) and (kg m/s2) t = time (s) CCBHS | 2025
- 11. IMPULSE CHANGE OF MOMENTUM Imaginea car with a mass of 1500 kg at a speed of 16 m/s. Its momentum is 24,000 kg m/s. ∙ We can express the initial momentum of the car as; 8 CCBHS | 2025
- 12.
- 13. IMPULSE CHANGE OF MOMENTUM Ifthe car speeds up to 20 m/s, the car's momentum changes to 30,000 kg m/s. This ∙ shows that a body changes its momentum when it changes its velocity. We can express the final momentum of the car as; 10 CCBHS | 2025
- 14.
- 15. IMPULSE CHANGE OF MOMENTUM Todetermine change in the momentum of the car, we simply subtract the final momentum with the initial momentum 12 CCBHS | 2025
- 16. 13 LAW OF CONSERVATION OFMOMENTUM When two objects collide, the forces acting between the two are equal in magnitude but in opposite direction. CCBHS | 2025 F1 = -F2 Same force but different direction

- 19. COLLISION Types of Collision: Elastic Collision Objectsbounce off each other, and momentum is conserved. (e.g., billiard balls hitting each other) Inelastic Collision Objects stick together, momentum is still conserved but some energy is lost. (e.g., car crash where cars stick together) 16

- 22. If the footballhalfback experienced a force of 800 N for 0.9 seconds to the north, determine the impulse. Given: F = 800 N t = 0.9 seconds 18 Required: I = ? Equation: I = F • t Solution: I = (800N)(0.9s) I = 720 N • s Answer: I = 720 N • s CCBHS | 2025
- 23. A 70 kgcyclist increases their speed from 10 m/s to 25 m/s in 4 seconds. Find the force exerted to cause this change in velocity. Given: Mass = 70 kg Initial velocity ( ᵢ) = 10 𝑣 m/s Final velocity ( ) = 25 𝑣𝒇 m/s Time ( ) = 4 s 𝑡 19 Required: F = ? Equation: Ft = m(Vf Vi ) − or F = m(Vf Vi ) − t Solution: F = m(Vf Vi ) − t F = (70kg)(25 10 ) − 4s F = (70kg)(15m/s ) 4s F = 1,050kg • m/s 4s Solution: F = 262 kg • m/s s Answer: F = 262 N CCBHS | 2025
