speed and acceleration Flashcards
speed
the rate of change of position
how quickly an object can move from one place to another
formula for speed
distance/time
units for speed
m/s
formula for distance
speed x time
formula for time
distance/ speed
slope definition
the steepness of a line
formula for slope
y2 -y1/x2-x1
acceleration definition
the rate of change of velocity
formula for acceleration
change in speed/ time taken
units for acceleration
m/s/s
deceleration definition
the reduction of speed
displacement
the distance in any given direction
velocity
the speed in any given direction
acceleration due to gravity
a falling object will acceelerate at aprox. 10m/s/s due to gravity
object may not fall at 10m/s/s due to air resistance
in a vaccum all objects, will accelerate the the same rate
