Final Assignment By Yamilet Cruz

Newton's 1st law Newton’s 1st law says that an object will not move until a force Is acted upon it. Ex. This roller coaster will not stop moving until a force is acted upon it.

Newton’s 2nd law Newton’s 2nd law says the more mass an object has the more force you will need to move that object Ex. These children more need more force to move the big rock because it has a greater mass than the small rock.

Newton's 3rd law Newton’s 3rd law says that for every action there is an equal and opposite reaction. Ex. one person is applying more fore to the other person

Gravity Gravity is the force of pulling together all matter gravity is what keeps us down on the ground. Ex. Gravity pull the apple down from the tree.

Acceleration When an object's velocity changes its called acceleration. Acceleration is the increase of speed. Ex. this is acceleration because the car has increased in speed.

Resistance Resistance is anything that slows, stops or keeps movement from happening Ex. Walking through mud would slow you down

Force Force is a push or a pull upon an object It may causes an object to undergo a change in speed, a change in direction, or a change In shape. Ex. This person is applying force on this box.

Potential Energy Potential energy is when an object is in the position of having the capacity for movement. Ex. This roller coaster is about to go down

Kinetic energy Kinetic energy is the energy of motion whether it is vertical or horizontal motion it is kinetic energy Ex. this man is running therefore it is Kinetic energy

Chemical change A chemical change produces a new substance For example if you put something in a fire a new substance will be made.

Physical changes A physical change is when no new substance is made Chemical bonds are not broken in a physical change Ex. This ice cream will melt but it will still be the same substance.

Heterogeneous mixtures heterogeneous mixtures is a mix when you can see the different particles For example you can see the different thing in this trail mix.

Homogeneous mixtures Homogeneous mixture is when you can not see different particles and it looks like one this chocolate milk contains 2 different substances but it appears as one

Compounds Compounds are things that are chemically combined can be found almost anywhere Ex. This desk is chemically combined

Elements Elements are any substance that contains only one kind of an atom

Atoms Atoms are the basic building blocks of matter that make up everyday objects For example any thing that has matter like this table

Radio waves The slowest waves Radio waves have the longest wavelengths in the electromagnetic spectrum. They also carry signals for our television and cell phones. Ex. Cell phones and television use radio wave

microwaves The 2nd slowest wave Microwaves have wavelengths that can be measured in centimeters Ex microwave oven ,Stars also give off microwaves

Inferred Waves The 3rd slowest wave Are just below visible red light in the electromagnetic spectrum They're given off by hot objects you feel them as warmth on your skin. Ex. stars, lamps, flames

visible light The 4th slowest wave Visible light waves are the only electromagnetic waves we can see. Red has longest wavelengths and violet has shortest wavelength Ex. light bulb, filming lamp

Ultraviolet Waves The 5th slowest wave Ultraviolet (UV) light has shorter wavelengths than visible light Ultraviolet rays can be used to kill microbes Ex. UV lamps to sterilize surgical equipment

X-rays The 6th slowest wave X-rays have smaller wavelengths therefore higher energy than ultraviolet waves. They will pass through most substances Ex. X-rays are given off by stars, X-ray machine

Gamma waves The fastest waves Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum Ex. they are used to kill cancer cells,

Matter Any thing that has mass and take up space Ex. A table, a dog, paper, even air is matter

The 3 states of matter Solid- particles don’t really move around Liquid- particles move around but not to much Gas- particles move around a lot

Work When ever something is moved from one place to another. Ex. Moving a book form oneself to another or digging a hole in construction

Power The amount of work that can be done in a period of time is power. Ex. Somebody doing their daily exercise.

Speed Distance traveled by an object (regardless of its direction) to the time required to travel that distance.

Momentum The force or speed of a movement. Ex. The car is getting momentum

Five phase changes Melting point –going from a solid to a liquid Freezing point –going from liquid to a solid Boiling point –going from a liquid to a gas Condensation-going from a gas to a liquid Sublimation – going from a solid to a gas

Observations An observation is something you notice using your senses. It is the 1st step done in the Scientific Method This man is looking for something.

Research Question A Research Question is a question that must be testable, using your observation. It is the 2nd step in the Scientific Method

Collecting Variables There are 3 different variables, IV, DV and CV IV is what you change, DV is what changes because of what you changed, CV is what stays the same in an experiment This is the 3rd step in the Scientific Method

Procedure The procedure tells the steps you will take in your experiment. This is the 4th step in the Scientific Method This picture shows steps of what they will be doing

Analyze Data Is putting your information together after you done with your experiment. This is the 5th step in the Scientific Method This picture shows analyzed data.

Conclusion A conclusion is tell what you have learned in your experiment. This is the last step in the Scientific Method
