Sound Energy
The bark of a dog
the beep of a car’s horn
Pose this question to your students:  Does the sound of a car’s horn have more energy than the sound of someone whispering? You can explain that the horn has more energy because the louder something is, the more sound energy it has.

Ultrasound
Example of Ultrasound lesson:
Definition:
Ultrsound like sound, that is mechanical energy transmitted by pressure waves in a material medium.
Classification:

ØLongitudinal waves: (transmitting in solid materials, liquids and gases): direction of particle vibrations is parallel to wave propagating direction Þ is applied in medical ultrasound.

Exp: sound waves in air.

ØTransverse waves: (transmitting in solid materials): particle vibrations is perpendicular to the direction of propagation.

Exp:

1. The wave at a stadium.

When you do the wave at a football game (for example) the wave's momentum propagates (flows) along (parallel) to the stadium seating. However it also oscillates (rises and falls) perpendicular to the direction of its propagation.

2. The vibration of a guitar string.

When you strum a string on your guitar the energy flows down (parallel to) the body of string. The string simultaneously oscilates perpendicular (at 90 deg) to the strings body, thus generating sound waves.

ROBOTICS
Place a mouse at a given position on the table. The lecturer uses his/her hand to pick up this mouse, then ask students what problem in controlling robot arm.

Modeling of Mechanical systems:
The spring:
F = ky
where k is stiffness constant
y  is the extension or compression

The springs store energy:
W = 1/2 ky^2

Game:
Give the students different springs: Hard springs and soft springs.
Ask them to compress or extend the spring.
They can see: Soft springs are easy to do, but it is difficult for hard springs.
When one student release the spring, it release the energy and comeback to original shape.
