velocity and acceleration

define speed

how fast an object is travelling, this doesnt include the direction.

define velocity

how fast an object is travelling, it also includes the specific direction that it is travelling.

What is the formula for average speed (symbol and word)

Average speed = distance / time

distance = v

time = t

average speed = s

s = d / t

what is acceleration

how quickly the velocity is changing, the change in velocity can either be change in speed or change in direction or even both .

what is the symbol for acceleration

m/s²

what is the formula for acceleration (not suvat)

Acceleration = final velocity - initial velocity / time taken

acceleration = a

final velocity = v

initial velocity = u

time taken = t

what is the formula for acceleration (suvat)

final velocity = initial velocity² + (2 x acceleration x distance travelled)

final velocity = V

initial velocity = U

Acceleration = a

Distance travelled = s

what is the mathematical symbol when an object is decelerating

negative symbol
