Sample Problem:Martin rides a bicycle at 1.5 m/s south. Ten minute later, he isdriving at 3.0 m/s south. What is Martin’s acceleration?

Acceleration

Given: Vi = 1.5 m/s t = 10 s

Vf = 3.0 m/s

Solution: a = Vf – Vi = 3.0 m/s – 1.5 m/s = o.15 m/s2

t 10 s

WAVE

Describe each characteristics of waves;

Relate amplitude, frequency wavelength and wave velocity;

Analyzing situations involving characteristics of waves;

Objectives:

A microwave oven uses microwaves to cook food by transferring energy to the water molecules in the food. Containers that are water-free, like plastic, usually remain cool. Wrapping food in aluminum foil will reflect microwaves and the food will not cook. Metallic decorations on chinaware are susceptible to damage.

Everyday SCIENCE

Is a disturbance traveling through a medium or a vacuum.

Wave

Wave pulse is a single unrepeated disturbance

Wave train is a succession of periodic disturbances

are classified according to

Waves

nature direction of vibrations

Concept Map

wave is either

mechanical

electromagnetic

wave is either

transverse

longitudinal

Requires a material medium tobe produced and propagated

Mechanical Wave

can travel in vacuum (empty space) / does not require medium to be produced and propagated

Electromagnetic Wave

How do mechanical waves

differ from electromagnetic waves?

the particles of the medium vibrate perpendicular to the direction of the wave propagation

Transverse wave

Longitudinal wavethe particles of the medium vibrate parallel to the direction of the wave propagation

How do transverse waves differ from longitudinalwaves?
