Electrical Energy

A bolt of lightening is electrical energy. This is the same kind energy used by an electrical outlet. Electrical energy travels through power lines and then helps make lots of different machines work.

Motion Energy:
Moving things have energy. The faster something is moving, the more energy it has. Pose this question to your students: Which do you think has more motion energy, a book that is falling off a table or a truck driving down the road at 60 miles per hour? You can explain that the truck has more motion energy because it is traveling much faster than a book. Another reason why the truck has more motion energy is that the truck is much heavier than the book.

A 1300 kg car moving at 20 m/s and a 900 kg car moving at 15 m/s in precisely oppositedirections participate in a head-on crash.
miskamm [114]

Given

Car 1

m1 = 1300 kg

v1 = 20 m/s

m2 = 900 kg

v2 = -15 m/s

(Negative sign shows that direction of car 2 is opposite to car 1)

Procedure

As per the conservation of linear momentum, "The total momentum of the system before the collision must be equal to the total momentum after the collision". And this applies to the perfectly inelastic collision as well. Then the expression is,

\begin{gathered} m_1v_1+m_2v_2=(m_1+m_2)v \\ v=\frac{m_1v_1+m_2v_2}{m_1+m_2} \\ v=\frac{1300\operatorname{kg}\cdot20m/s-900\operatorname{kg}\cdot15m/s}{1300\operatorname{kg}+900\operatorname{kg}} \\ v=5.681m/s \end{gathered}

Thus, we can conclude that the speed and direction of the cars after the impact is 5.68 m/s towards the first car.
