Streetcar Vs. Light Rail

For our ABL project we chose the Modern Streetcar
over the modern Light Rail system.

We chose the Modern Streetcar over the Modern Light
Rail system because the Modern Streetcar is more
easier to operate than the light rail system.

The Modern Streetcar has many different qualities that
are more helpful than the light rail system. Some
qualities are being able to minimize traffic & being able
to move along streets.

The Modern Streetcar

The Modern Streetcar is a form of
transportation that is very accessible to many
people.

Most modern streetcars are ran on electricity
and some are ran on diesel fuel.

Streetcars usually run on tracks in the streets.
They may also run in between towns, and cities.


The streetcar is usually lighter and shorter than
conventional trains. A streetcar may also run on
ordinary railway tracks.

Some of the first streetcars were driven by
horse; while others were operated by steam or
being cable-pulled.
Modern Streetcar &
Science



Science is a big element in any type of machine; in
speaking of machines lets talk about all the simple
machines that work together to make the modern
streetcar the compound machine it is.
But before we explain what simple machines are present
in a streetcar you need to know what a simple machine
is.
A simple machine is a machine that makes work easier.
There are 6 types of simple machines: Inclined Plane,
wedge, screw, pulley, lever, and wheel and axle.
Simple Machines in a
Streetcar


Some of the simple machines that are present
in the modern streetcar is a wheel & axle, lever,
and in some instances an inclined plane.
Some examples of the wheel & axle's that are
present in the streetcar is the steering wheel,
and the wheels, Inclined plane ex. ramp, lever
ex. door.
Velocity and Acceleration




Velocity and acceleration are also other
elements that are present in a streetcar.
Velocity is speed in a given direction.
Acceleration is a increase in speed or a change
in direction.
Both of these elements are present in a
streetcar because a streetcar is in motion and
anything in motion either uses velocity or
acceleration.
Energy Transformations



Some of the energy transformations that occur in a
streetcar is chemical to mechanical, and chemical to
electrical.
Due to the law of conservation of energy, energy is not
created nor destroyed but transformed into different
forms.
In conclusion we chose the modern streetcar for many
reasons because it has many different scientific qualities
such as simple machines, velocity and acceleration, and
energy transformations that make it easier to use for
everyone.
