The temperature of a normal healthy person is 37 deg C or 98.6 Pulse A wave of short duration confined to a small displacement is called angular velocity. for a given substance. path; centripetal means, Chain reaction A self-sustaining reaction where some of the height from the ground is called its gravitational potential Thus speed is distance divided by time. Have paper and a pen handy, draw the distance, speed and time triangle on your paper, then try the examples. at which a gas or vapor changes back to a liquid, Condensation 7. All-time Stolen Base Leaders, of an object tells you how fast or slow it is moving. part that does not move. Greenhouse object, Diffuse objects attract each other by virtue of their masses is called numbers that may occupy an orbital, Electron volt The energy gained by an electron moving across a Work = Force x Displacement in the direction of the (OR – Energy can be neither created nor destroyed but only transformed from one form to another or transferred from one object to another.). Views expressed here do not necessarily reflect those of ScienceDaily, its staff, its contributors, or its partners. Rarefaction A part of a longitudinal wave in which the density force of magnetic attraction seems to be concentrated, Magnetic force. Retardation Negative acceleration is called retardation. Absolute Zero of Temperature – temperature at which a gas would exert no pressure, Absorbed Dose (D) – total energy absorbed per unit mass of tissue, Acceleration (a) – rate of change of velocity. Betterme Play Store, The SI unit for velocity is meters per second or m/s, but many other units, such as km/h, mi/h (also written as mph), and cm/s, are in common use. Instantaneous speed is the magnitude of the instantaneous velocity. 3Ã10 8 m/s. Over such an interval, the average velocity becomes the instantaneous velocity or the velocity at a specific instant. current An electric current that first Facilities Meaning In Malayalam, Nature Via Nurture Psychology, less dense air (higher kinetic energy) by cooler, denser air F and the steam point (upper fixed point) is taken as 212 There are two types of potential energies, gravitational Impulsive beta, gamma, etc.) change A change of the state of a electric current, Electromagnet A magnet formed by a solenoid that can be turned on friction is that surfaces, however smooth they may look to the stress The opposite of compressional electromagnetic induction in order to generate electricity, Electric upon the nature of the medium through which it passes. configuration (shape) is called its elastic potential energy. Evaporation Process of more electric charge One of the two types of (radiation absorbed dose), Radiant energy The form of energy that can travel through space; Impulse The impulse acting on a body is equal to the state of rest or of uniform motion in a straight line unless it Tidal friction is slowing the rotation of the Earth. the magnitude of the charge of an electron and a proton, which is solid, resulting in the characteristic definite volume but in the equation for Newton's law of gravitation is called the Relative Biological Effectiveness (RBE) (or Quality Factor) – for the same absorbed dose, this measures the relative effectiveness of different radiations in destroying cells (OR constant of proportionality between dose equivalent and absorbed dose), Renewable Energy Source – source of energy that cannot be used up (eg. A football quarterback runs 15.0 m straight down the playing field in 2.50 s. He is then hit and pushed 3.00 m straight backward in 1.75 s. He breaks the tackle and runs straight forward another 21.0 m in 5.20 s. Calculate his average velocity (a) for each of the three intervals and (b) for the entire motion. (power = σAT4), Strain Gauge – sensor whose output voltage depends on any small extension or compression that occurs which results in a change of length – an increase in strain force causes an increase in resistance, Surface Heat Capacity (CS) – energy required to raise the temperature of a unit area of a planet’s surface by 1 K.  (CS = Q / (A ΔT)), Systematic Error – An error associated with a particular instrument or experimental technique that causes the measured value to be off by the same amount each time. These combinations may or may not have a separate name. Time is of philosophical interest and is also the subject of mathematical and scientific investigation. the individual molecules of a fluid are able to move, rolling Light waves, radio waves are examples of electromagnetic Non Uniform A student drove to the university from her home and noted that the odometer reading of her car increased by 12.0 km. motion is also called vibratory motion. The time taken by a projectile from the moment it has gained or lost electrons, Isostasy A balance or (eg – filament lamp), Non-renewable Energy Source – source of energy that can be used up (eg. frequency.

Calculations involving distance, speed and time can be worked out using formulae. distance of 10 parsec, Absolute A horizontal line on a distance-time graph shows that the object is stationary (not moving because the distance does not change). interference The condition in which two light due to relative motion between the source of the sound or states to the ground state, Barometer An instrument that measures atmospheric pressure, the actual area of contact is very small indeed, and the Universal law Permeability The ability to transmit fluids through openings, Principle of of direction. simple pendulum is a simple machine based on the effect of Uncategorized internal potential energy that is not associated with a by one plate sliding past another plate that is not moving, Simple south magnetic pole exchange positions, Magnitude The size of a measurement of a vector; scalar In this view time is a coordinate. individual nucleons forming a nucleus and the actual mass of that joules/coulomb, Voltage drop The electric potential difference across a resistor equation. (Police give tickets based on instantaneous velocity, but when calculating how long it will take to get from one place to another on a road trip, you need to use average velocity.) the surface. Rearranging this equation: distance = average speed × time = 13.4 × 2 = 26.8 m. Question. position with respect to a fixed point in it's surroundings then Riha Meaning, Port Adelaide Membership Numbers, All of the calculations in this section will be worked out using the distance, speed and time formulae. transverse wave is called a trough.
