We truck at rest was hit by

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.
