.

2. • is the product of mass
(m) of the object and its
velocity (v)
• In equation,

3. • The factors that affect
momentum are mass
and velocity.

4. • is the difficulty faced by
a moving object to
undergo a sudden stop
• In equation,

5. SLOW RUNNER
FAST RUNNER
Which would be harder to stop, the
fast runner or the slow runner?

6. SLOW RUNNER
FAST RUNNER
The higher the velocity, the greater the
momentum.

7. RUNNER 1
RUNNER 2
• When the mass is greater, the
momentum is greater.

8. RUNNER 1
RUNNER 2
Both have the same velocities but runner 1 is twice the
mass of runner 2. Which would be harder to stop?

9. SEATBELT

10. AIRBAGS

11. Lesson 2:
Conservation of Momentum
The Law of Conservation of
Momentum states that the
total momentum of objects
that collide is the same before
and after the collision.

12. Lesson 2:
Conservation of Momentum

14. Lesson 2:
Conservation of Momentum
The total momentum of an
isolated system of objects is
conserved regardless of the
nature of the forces between
the objects.

15. Lesson 2:
Conservation of Momentum
ISOLATED SYSTEM
- is a system that has no
external forces exerted on it

16. Lesson 2:
Conservation of Momentum
ELASTIC COLLISION
- when colliding objects
separate after the collision

18. Lesson 2:
Conservation of Momentum
INELASTIC COLLISION
- when two objects stick
together after the collision
