# Physics equations and formulas

Kinematic Equations and Graphs The goal of this first unit of The Physics Classroom has been to investigate the variety of means by which the motion of objects can be described. The variety of representations that we have investigated includes verbal representationspictorial representationsnumerical representations, and graphical representations position-time graphs and velocity-time graphs. Definition Acceleration The rate of change of velocity. Value can be found from the gradient of a velocity-time graph. A flow of 1 coulomb per second is 1 ampere Amplitude The maximum displacement of a point of a wave from rest position.

Height of a crest or depth of a trough measured from the undisturbed position. For a sound wave, the greater the amplitude, the louder the sound. Angle of incidence The angle between an incident ray and the normal to a surface Angle of reflection The angle between a reflected ray and the normal to a surface Angle of refraction The angle between a refracted ray and the normal to a surface Atmospheric pressure The air pressure in the earth's atmosphere.

Atmospheric pressure is about Pa near sea level and decreases with height above ground. Average speed The total distance traveled divided by the total time taken. Boiling A process by which energy supplied changes a substance from liquid to gas without a change in its temperature.

Cathode ray oscilloscope An instrument that enables a variety of electrical signals to be examined visually. It is used for measuring direct current and alternating current voltages, short time intervals and frequency and for displaying waveforms Celsius scale A temperature scale where the lower fixed point is the ice point and the upper fixed point is the steam point Centre of gravity The point at which the entire weight of an object appears to act Condensation A process by which energy released changes a substance from gas to liquid.

Conduction The process by which thermal energy is transmitted through a medium from one particle to another. Convection The process by which thermal energy is transmitted from one place to another by the movement of the heated particles of gas or liquid. Converging lens A lens that can bring a parallel beam of light passing through it focus to a point. It is thicker in the middle than at the edges. Coulomb C The SI unit of electric charge. Crest The highest points on a wave Critical angle The angle of incidence in the optically denser medium for which the angle of refraction in the less dense medium is 90o Total internal reflection occurs when the angle of incidence is greater than the critical angle.

It is thicker at the edges than at the centre. Echo Reflected sound heard after an interval of silence. Electric current The rate of flow of charge.In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force.

For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement).
