Elastic Vs Inelastic
One example of Elastic is when I throw a bouncing ball to another bouncing ball and soon BOTH balls will bounce off each other. An Example of inelastic is when I start running and I suddenly trip on my shoelace, I collide with the ground making me get stuck with the ground not wanting to get up. So the ground and I are stuck together. An elastic collisions is when 2 items bounce off of each other when they collide. An inelastic collision is when 2 items are stuck together.

Phase Change

Today I went to go make coffee and I boiled up hot water. While I was boiling up hot water I can see there is water bubbles in my water and I asked to my self what is going on? Well the reason why my boiling water was making bubbles was because it was evaporating. First I pored liquid into a pot and I set it in my oven. The fire was heating up the water which soon the water was turning into a gas. When the liquid was turning into a gas that is called evaporation. The reason why my boiling water was making bubbles was because the liquid was turning into a gas by evaporating. Heat was being added to the water which made the water evaporate soon turning it into a gas. At first the water was a liquid which turned into a gas by adding heat to the liquid.

Too Hot/Too Cold
Too Hot/Too Cold
3 things that heat up at different rates is Metal, Rubber, and Laundry Dryers. The Metal heats up the quickest because heat moves much faster in the metal which its a conductor. Rubber takes a long period of time to heat up (but eventually it will burn) I think rubber heats up slow because rubber is an insulator and insulators takes longer to heat up since heat moves much slower in them. Laundry Dryers take very little time to heat up because in the dryer its already producing heat while it spins around the clothes. Heat is being transferred to the wet clothes making the clothes dry up, and making the dryers spin make the clothes dry up even faster!

Doppler Radar
Doppler Radar
The doppler weather forecast is used to research about weather so that people can make predictions on precipitation, to calculate its motion and to estimate its type of rain hail snow etc. People mostly use pulse doppler-radar so that they can determine the motion of rain dopplers. How waves are used to show that weather is happening is by we see the waves in colors of the rainbow (ROYGBIV). Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. A Doppler Radar is combined with satellites which allows forecasters to provide us with upcoming thunderstorms, tornadoes or any other storm that could cause damage. Doppler Radars work by the satellites measuring the changes in the frequency of the signal the radar gets to conclude the wind.

Interference
Interference
The difference between a constructive and a destructive interference is that a constructive interference is the crest of a wave that is super positioned with another crest but a difference wave it can also be a trough with a trough and all of this will allow to increase the amplitude. A destructive interference is when the crest of a wave is also super positioned with the trough of another wave but its to decrease the amplitude. An example of something that interferes and makes something smaller is when hot water is in contact with snow. The hot water makes contact with the snow making the snow dissolve into the ground. An example of something that interferes with and makes it larger is water and a plant. The plant needs water to grow which makes the plant increase in size. It becomes larger than it already is.

The lab what we did today in class was Miss Reid was trying to do a certain wave. The slinky was at two ends one in Miss Reid's hand and the other was at the laptops. Miss Reid swing the slinky up and down for 10 seconds. We had a specific wavelength which was measured in meters and the frequency (how many times Miss Reid swinged the slinky up and down for 10 seconds). Then at the end we measured the speed (frequency/10 seconds) and as a result each of them where 9.6 m/s. What I learned is that it doesn't matter the wavelength or frequency because at the end you will get the same results (depending on how long you swinged the slinky. I learned that a transverse wave is a type of wave where the particles are perpendicular meaning they go across. A compression wave is a type of wave where the particles move parallel to the direction of the energy. We got to see examples of transverse waves and compression waves.

Something in my life that I think should affect something but doesn't is weight on floating object. I always thought that the weight mattered if an object can float or not. The lighter the object the easier it will float, the heavier the object toe easier it will sink. But of course that's wrong. I think that weight should affect the object capability on whether or not it should float because a rock is heavy and that sinks but a penny is light and that also sinks. I know that weight does have some affect on floating object but that's not the main point. The reason why object float is because through buoyant, and the dense on the fluid.
