We all know that Momentum
means inertia in motion. It 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.
