Physics Flashcards
Speed is calculated by using what formula ?
S=D/T
Formula used for velocity
v=d/t
Takes into account speed and direction
Velocity
Calculates the change in an objects velocity over time
Acceleration.
Calculated by multiplying the mass of an object by its velocity
Momentum
Force that is applied to an object over time and it’s equation
Impulse
Property of matter by which an object in motion tends to continue traveling Ina straight line, where’s an an object at rest tends to stay at rest unless object is acted by force. It takes a force to move an object or change it’s direction in motion
Newton’s first law
Relationship between the forces applied to an object and the acceleration of the object. The greater the force of the object the greater it’s acceleration.
Newton’s Second law
When an object applies a force to a second object; that object applies opposite and equal force to the first object
Newton’s third law
Are continuous and have amplitude, frequency and wavelength
Waves
The highest and lowest points of a wave are called?
Crests and troughs
Highest peak in a wave is called
Crest
Lowest point on a wave is called
Troughs
The number of complete waves that pass through a point over a given amount if time
Frequency
Have vibrations that are perpendicular (at right angles) to the direction in which the wave is moving
Transverse wave
Have vibrations that are moving in the same direction as the wave
Longitudinal wave
Exhibits both wave and partial
Light
Light particles are called
Photons
Takes place when a wave that is spreading out its object and it continues to travel, bends around the object
Diffraction
An object that losing electrons is?
Becomes positively charged
Flow of a charge from one terminal of a circuit to another
Current
Is the electrical potential sited energy that a power source has
Voltage
The ability of a substance to stop the flow of a current
Resistance
Term used to describe objects that are in motion
Kinematics
