DEFINITION Flashcards
TRANSVERSE PULSE
The displacement of particles perpendicular to the direction of movement of a pulse
TRANSVERSE WAVE
when the particles of a medium vibrates perpendicular to the direction of the motion of the wave
AMPLITUDE
A single disturbance propagated by medium
LONGTUDINAL WAVE
A wave in which the particles of a medium vibrate parallel to the direction of movement of a wave
REFLECTION
The echo of sound
ULTRASOUND
SOUNDS ABOVE THAT ARE ABOVE 20000Hz
PHONTON
Energy packets found in EM waves that transfer energy to particles of matter
LAW OF CONSERVATION OF CHARGE
The net charge of an isolated system remains constant during any physical process
Potential Difference
Energy transferred per unit charge between two points in a circuit
EMF
The amount of electrical energy transferred by the battery per unit charge
CURRENT
The rate at which electrical charge flow
SCALAR
A physical quantity that has only magnitude
VECTOR
A physical quantity that has both magnitude and direction
Position
Is the place where an object is relative to the reference point
REFERENCE POINT
A point from which the position of the object is measured
SPEED (MECHANICS)
The rate at which the distance covered changes
VELOCITY
Rate of change of position of an object
AVERAGE SPEED
The rate of change of the total distance
UNIFORM SPEED
A body travels at a constant speed if it covers equal distances in equal time intervals
ACCELERATION
Rate of change of velocity of an object
CONSTANT ACCELERATION
A constant increase or decrease in velocity in equal time intervals
INSTANTANEOUS VELOCITY
RATE OF CHANGE IN POSITION
GRAVITATIONAL POTENTIAL ENERGY
The energy an object has due to its position within the gravitational field relative to the reference point
MECHANICAL ENERGY
The sum of an object’s gravitational potential and kinetic energy at a specific position
