momentum, an helicopter parked in a hangar or a car going down a hill? Impulse Momentum selfcheck: A 2500kg school bus from the previous

house moves 25 m/s to get the last

student from their house. The bus carries 15 students, and each student weighs 900kg.

What is the momentum of the school bus?

selfcheck: selfcheck: A car going down a hill

has a greater momentum,as long

as it continues moving Solution:

Cart #2 has the greatest acceleration.

Recall that acceleration depends on force

and mass. They each have the same mass,

yet cart #2 has the greater force. Physics * what comes to your

mind when you heard a

basketball game announcer

say that the team lost its

momentum and so it lost the

game?

* ask yourself how a football

player who is running down a

field is able to knock down

players who are in his way? In this presentation :

*we will discuss about

the momentum and how

is it related to physics.

*give a brief summary

about it.

*explain the importance

of impulse and momentum

in real life situations

particularly in road safety

*and solve a sample problems.

vi vf Momentum:

- is commonly used in sports, we even make it as an adjective or a noun in our sentences to add layers of meaning. But what is momentum in physics?

When a sports announcer says that a team has team is really on the move and is going to be ha physic concept. To stop such an

against its motion for a given period the momentum they mean that the

rd to stop.The term momentum is a object,it is necessary to apply force of time. The usage of the word in these situations suggests the idea of mass in motion and therefore of inertia. remember! that heavy or massive objects have greater momentum even if they are moving slowly. But this does not seem to be true always. -A light object can have as much momentum as a heavy object,depending on how fast it moves. -the linear momentum of an object of mass(m), moving with a velocity(v),

is defined as the product of the mass and the velocity. It is represented by the symbol of (p).

p=mv

A 3000kg bus from Laguna moves 30m/s to Makati. What is the momentum of the bus? p=mv

solution:

=3000kg(30m/s)

=90000kg.m/s we can find this change in momentum by

rewriting Newton's II law, Fnet=ma , in a

more general form. Fnet=ma

=m( v/ t),since a=

Fnet=m v/ t

and

Fnet= p/ t,since m v= p.

Therefore,

Fnet t= p or

Fnet t=m(vf-vi) v/ t *the unit is kg.m/s Impulse-Momentum

Theorem -the equation states that net external force,

applied to an object for a certain time interval,

will cause a change in the object's momentum

equal to p and t.

*I=Fnet t

*I= p

*I=m v

Impulse: the change in the

momentum of a moving object. Edward is playing badminton with his friends. He

hit a 0.5kg shuttlecock, giving it a speed of 70m/s. What impulse does he impart? I= p=m v

=0.05(70)

=3.5kg.m/s Real Life situation it is really

important for us

to have it and we must thank

Gottfried Leibniz for giving his

the END A 0.5-kg cart (#1) is pulled with a 1.0-N force for 1 second; another 0.50 kg cart (#2) is pulled with a 2.0 N-force for 0.50 seconds. Which cart (#1 or #2) has the greatest acceleration? Explain. questions answers ! the airplane has a

zero momentum since

v=0 - # of the passengerxthe mass of it

15(900kg)

=13500kg+2500kg

=16000kg

p=mv

=16000(25)

=40000kg.m/s ...therefore the momentum

of the school bus

is 40000kg.m/s from

the previous

house to the house

of the last passenger. time for doing this and also for some philosophers who contributed a lot. when we need to punch something

it helps also, bec. w/ a lot of time

we can protect ourselves bec. we have

a great force. and also

in sports All of us have a problems but with determination and full force of energy we can achieve our goals in life. We can apply the formulas to have a good decision and use it for good. * problems can not stop us in our dreams because momentum is hard to stop, and we are the momentum in our own world and its our decision to stop it or go for it. * The impulse-momentum theorem is used

by highway engineers to determine stopping

times and safe following distances for cars and trucks. The theorem is also used to design safety equipment that decreases the force exerted on the human body during collisions. Firefighters make use of nets and giant air mattresses to catch people who have jump from tall building. reference:
