speed and acceleration Flashcards
what is the unit for speed
meters per seconds m/s
mention the kinds of speed
constant speed instantaneous speed and average speed
what is instantaneous speed?
is the speed in an specific moment
what is constant speed?
the same speed in a constant motion
what is average speed?
is the distance traveled divided by the total time taken to travel that distance
what is acceleration?
change in velocity
name the kinds of acceleration
positive acceleration and negative acceleration
what is positive acceleration?
when the speed is increasing
what is negative acceleration?
when you are going lower
what is velocity?
is speed with direction and time
formula for velocity
same as speed d/t
formula for acceleration
final velocity - uncial velocity divided by time Vf-Vi/time
what is speed?
the amount of distance traveled in a specific period of time
