when a traffic accident is investigated, it is common for the length of the skid marks to be measured. how could this informatio

This information could be used in the following ways: the braking distance of a skidding car will depend on its initial speed and the coefficient of kinetic friction.

Thus, if the coefficient of friction is known the initial speed can be determined from the length of the skid marks.

What do you mean by Initial speed?

Initial speed can be described as  how fast an object travels when gravity first applies force on the object. It can be represented in the form of (u) and is generally measured in metres per second (m/s).

It can be represented in three ways.

  • v2=u2+2as
  • v=u+at
  • s=ut+0.5at2

Through these formulas we can calculate the initial speed of any object. It helps in understanding various velocities, time principles.

svlad2 [7]

If current is passed through two parallel conductors in the same direction and the conductors are placed near each other, they will​ attract each other.

<h3>What is electric current?</h3>

Electric current can be defined as the flow of electrons.

Since electrons are easily removed from atom and are very mobile, the flow of electrons constitute an electric current.

Materials which allow electric current to flow through them are known as conductors. Examples of conductors are metals, and electrolytes.

On the other hand, materials which do not allow electric current to pass through them are known as insulators. Examples of insulators are wood and rubber.

The flow of current is known as electricity.

Parallel conductors with current flowing through them in the same direction are attracted to each other as a result of a magnetic field produced by the flow of current.

In conclusion, conductors allow electric current to pass through and the flow of current through a conductor produces a magnetic field.
