Acceleration-Is an object changing speed.If an object changes direction its velocity changes which means its acceleration is changing too. The formula to find the acceleration of an object is change in velocity divided by time.(Final velocity-Initial velocity/ Final time-Initial time) Danny

Accuracy-the state of being accurate
by:jacky Valencia

Adiabatic- The process in which no heat is lost or gained in a system.(Gabriel Farran)

Angular Momentum: Circular momentum of an object.Angular momentum is a conserved quantity: a system's angular momentum stays constant unless an external torque acts on it.
By: Raymundo Cruz

Average Velocity-is rthe total displacement divided by the time interval during which the displace ment occurred. By:jacky Valencia

Collision---> means the action of bodies or objects striking or coming together.(Reyna O.)

Conduction: the transfer of energy from particle to particle; transfer and distribution of heat energy from atom to atom within a substance (Janice Villarreal)

Contact Forces: a force between two objects (or an object and a surface) that are in contact with each other -Debbie

Convection: the transfer of heat by the actual movement of warmed water (Janice Villarreal)

Conservation of Momentum- Momentum in an isolated system may be transferred during collisions, but not destroyed.(IRMA CRUZ)

Delta- a change in a variable, such as a change in X, represented by a triangle Christina Giordano

Displacement- is a change in position; it's not always equal to the distance traveled. The SI unit for displacement is meter (M)
*Karen Rayas*

Distance- The measurment of how much one is moved from one location to another. Often confused with displacement, the distance is the total amount how much something moves, weither it is forward or backwards.

Efficiency: Accomplishment of or ability to accomplish a job with a minimum expenditure of time and effort -Debbie

Elastic Collisions - a collision that results in two objects traveling away from each other (Christian santos)

Energy- The ability to do work

Entropy- 2nd law of thermodynamics (change in heat)
  • Entropy is a measure of disorder in a system. For example, the higher the disorder, the higher the entropy value.

Experimental Design-Manny

First Law of Thermodynamics- The increase in the internal energy of a system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings. As stated:This is the conservation of energy which means that energy is never created or destroyed, only transfered.

Free Fall- is motion only under the influence of gravity [Vanessa Zamora].

Gravity- A force which pulls objects with mass to each other. Gravity here on earth gives object weight. The force of gravity on earth is approximately 9.81 m/s/s {marcos.]

Heat Capacity- the amount of energy required to raise the tempurature of a substance by a degree (Clem Hernandez)

Heat - Energy that transfers between different objects with different temperatures. Heat energy is always transfered from the object with the hottest temperature to the coldest temperature. (Joseph Sosa)

Heat Engine- A device that uses heat energy to do work, it turns internal energy into mechanical energy (Armando Cortez)

Heat Engine- A divice that continuosly converts thermal energy to mechanical energy; it requires high temperarutre and a way to convert thermal energy into work. (Isaac S.)

Impulse- a measurement of the force applied and the time it is applied.(gerstine c.)

Impulse Momentum Change Theorem- change in an objects momentum is equal to the impulse applied to that object.(gerstine c.)

Inelastic Collisions - a collision that results in two objects traveling with one another (christian santos)

Instantaneous speed- the speed at which you are currently traveling at the moment(diana perez)

Internal Energy- It is the total energy stored in the atoms and molecules within a substance.(Jessica Sanchez)

Isothermal- The process in which temperature stays constant( Yesenia S.

Isovolumetric- A thermodynamic process that takes place at constant volume so that no work is done on or by the system.(diana perez)

Kinetic Energy- is the energy of motion

Mass- a measurement of an objects matter (yesica lopez)

Mechanical Energy- the total potential and Kinetic energy (yesica lopez)

Mechanical Work: the amount of energy transferred by a force -Debbie

Metric System- is a type of measurement.-Rosie Rodriguez

Metric Units- a decimal unit of measurement of the metric system (based on meters and kilograms and seconds); "convert all the measurements to metric units"; "it is easier to work in metric" -Josebg

Momentum- the product of the mass and velocity of an objec. -Leo

Newton's First Law of Motion- Every object will remain at rest or in uniform motion in a straight line unless it is made to change its state by the action of an external force.-Jaclyn

Newton's Second Law- The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. The object keeps on doing what its doing.

Newton's Thrid Law of Motion- For every action there is an equal and opposite reaction. - Lizbeth

Pressure- Force applied to a surface. pressure = force / area. {marcos.]

Potential Energy- Stored Energy of position possessed by an object. -Charles M. Ghiotto-

Projectile Motion- Projectile motion is the angle and arc that a object has traveled during free fall. [Ashley]{GEM} (Charlie helped me)

Radiation: is energy in the form of waves or particles that can be transmitted. {NormaCruz}

Scalar- A quantity that has a magnitude but no direction. For example speed. -Jaclyn Lopez

Scientific Notation- First you identify a problem or question to be answered. Then you formulate a hypothesis on what you believe the outcome of you experiment will result in. Next a controlled experiment, in which you regulate all factors you possibly can. Some aspects of a good experimental design are multiple trials, qualitative data, and many controlled variables. -Rosie Rodriguez

Speed- The rate at which an object moves. It's how fast an object goes in the distance covered. The formula is total distance divided by total time .---->Jose Almeda

Thermal Energy- energy due to the Kinetic energy and the potential energy.(alyssa)

Thermal Expansion- When a substance is heated, the temperature rises and expands ( Yesenia S.)

Thermal Equilibrium- State achieved when two objects with different temperatures transfer heat and become equal. -Siray Rodgers

Thermodynamics----> branch of physics that studies the effects of changes in temperature, pressure, and volume; studies the movement of energy and how it instills movement (reyna o.)

Thermometer: When the thermometer is heated, the volume of the liquid expands. The change in length is proportional to the temperature change.- Jerae Ortiz

Vector- a line that represents magnitude and direction. *Karen Rayas*

Velocity- An object's speed and direction of motion; the rate of change of an objects displacement. -Jaclyn Lopez

Wave- a disturbance that travels through a medium from one location to another location.

Work-a measurement of force multiplied by the displacement in the same direction as the force. Work formula work=forcexdisplacement
by Cindy Renteria

2nd Law of Thermodynamics- Heat flows naturally from a hot object to a cold object
