          We all know that Momentum is the
product of the mass and the velocity of an object (Momentum = mass x velocity).
Therefore, in shorthand notation, Momentum= mv. A moving object can have a
large momentum when either it mass or velocity is large or both are large. As
shown in my video, a blue truck which has zero in momentum for it was at rest,
was hit by a yellow truck having a large amount of mass causing it to have a
large amount of momentum too. In this part of my video, where the blue truck at
rest was hit by the yellow truck, Impulse is already present. Impulse, for what
we know, it is the change in momentum. Before the collision happened between
the two trucks, we have seen that the blue truck was at rest causing it to have
zero in momentum but after the collision happened, it already started to gain
and change its momentum for it started to change its velocity causing the
yellow truck to decrease its momentum. So, in changing momentum, both force and
time interval is important. Impulse, therefore, is the product of force and
time. Therefore, in shorthand notation, Impulse (J) = Ft. Let us now focus on
the different kinds of collisions we need to know. A collision, which is
generally considered to have two types, the elastic and the inelastic
collision, is where two things collide with each other. It’s just that in an
Elastic Collision, there is an involvement of momentum and a kinetic energy
while in an Inelastic Collision, only a momentum is involved and not with a
kinetic energy. Whether it is elastic or not, always remember that the momentum
of an object is always constant. Since in my video, the trucks collide with
each other and caused them to stick together, they are considered to be
perfectly Inelastic Collision. In this type of collision, different kinds of
kinetic energy like heat and potential energy are being lost. To compare this
with my video, the blue truck having zeroed in momentum has now doubled in
momentum and a half in velocity after having a collision with the yellow truck.
So if an Inelastic collision is the type of collision that we can call an
object that collides, Elastic Collision, on the other hand, is the type of
collision that allows or makes both objects bounce against each other. My video
is not an Elastic Collision for as we have seen that both trucks collide and
sticks together with each other until the end and never made Elastic Collision
happen in the situation.
