Physics
| Question | Answer |
|---|---|
| at rest | fluid statics |
| in motion | fluid dynamics |
| are substances that deform continuously under the application of force, no matter how small or weak this force may be | Fluids |
| Newtonian fluids have | constant viscosity |
| Non-Newtonian fluids have | variable viscosity |
| defined as the force per unit area it is also known as “stress” force exerted by a fluid on an object in contact with it unit is expressed in Pascal | Pressure |
| is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. | Electric charge |
| is the force exerted by the weight of the air in the Earth's atmosphere on a given area. | Atmospheric pressure |
| also known as “total” pressure equal to the sum of gauge pressure and atmospheric pressure | absolute pressure |
| an upward force exerted by a fluid on an object that is wholly or partially immersed in it occurs because the pressure in the fluid increases with depth due to the difference of pressure between the top and bottom surfaces of a submerged object | Buoyant force |
| is a branch of physics that deals with the study of heat and temperature and their relationship to energy and work. | Thermal physics |
| When objects are heated or cooled, the temperature changes and some properties of the materials change. These properties are called | Thermometric Properties |
| a measure of the average kinetic energy of the particles in a substance or system the degree of hotness of an object | TEMPERATURE |
| It is the energy which travels from high temperature to low temperature in a matter. It is also called thermal or internal energy. | HEAT |
| refers to the amount of thermal energy transferred between two objects due to a temperature difference | quantity of heat |
| is the transfer of heat through a material without the material itself moving | Conduction |
| is the transfer of heat through the movement of a fluid (liquid or gas). | Convection |
| is the transfer of heat through electromagnetic waves that do not require a medium to propagate | Radiation |
| is a state in which two or more objects or systems are at the same temperature, so there is no net flow of heat between them | Thermal equilibrium |
| refers to the tendency of materials to change in length in response to a change in temperature. | Linear expansion |
| also known as superficial expansion, refers to the tendency of materials to change in area in response to a change in temperature. | Area expansion |
| also known as cubical expansion, refers to the tendency of materials to change in volume in response to a change in temperature. | Volume expansion |
| is a branch of physics that deals with the properties of stationary or slow-moving electric charges and their behavior together. | Electrostatics |
| When you rub one material to another, their charges are | changed by friction |
| When two objects that are not in equilibrium touch, charges move between them. | Charging by Contact |
| Polarizing charges result in separation of the positively charged particles and the negatively charged particles. | Charging by Polarization |
| Charging by induction simply means creating a net charge without contacting another object. | Charging by Induction |
| When two charges are placed together with distance r between them, they both experience a force called | electrostatic force |
| gives the magnitude of the electrostatic force between two charges separated by a distance r. | Coulomb’s Law |
| states that for all linear systems, the total force is a vector sum of individual forces. | superposition principle |
| is the rate of flow of the electric field through a given area | Electric flux |
| is the energy that is needed to move a charge against an electric field | Electric potential energy |
| are components in a circuit which can store or release energy | Capacitors |
| is the flow of electric charge. In an electric circuit, it is the rate of flow of electric charge past a point or region. | Current |
| also known as electric potential difference, is the difference in electric potential between two points. | Voltage |
| is the opposition to the flow of electric current in a circuit. | Resistance |
| They are known ________because they do not lose their magnetic property once they are magnetized. | Permanent Magnet |
| can be magnetized in the presence of a magnetic field. | Temporary magnets |
| consist of a coil of wire wrapped around the metal core made from iron | Electromagnets |
| is the region around a magnetic material or a moving electric charge within which the force of magnetism acts. | Magnetic Field |
| are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. | Magnetic field lines |
| is a long coil of wire consisting of many loops or turns. If tightly wrapped, the magnetic field in its interior is almost uniform | solenoid |
