speed
is a measure of how fast or slow something moves
distance
is how far something travels
time
is how long it takes for something to happen and is measure in seconds, minutes, hours, days, months, years
formula for speed
speed equals distance over time
speed defintion
Measured as distance traveled per unit of time.
SI Unit
the scientific measure for speed is meters per second
A car goes 120 miles in 3 hours
its speed is 40 miles per hour
constant speed
means you are moving at a constant rate of sped like 50 miles per hour
traffic
does not move at a constant speed so we usually measure it by average speed
instantaneous speed
is your speed at a specific moment in time
calculation of instantaneous speed is difficult
because we do not move at a constant rate over time
average speed
the total distance traveled over a specific amount of time
calculation of average speed
is made using the formula speed equals distance over time
distance time graph
speed is measured by the slope or steepness of the line
distance time graph II
if the line is strange then the speed is constant
distance time graph III
if the line is curved the speed is not constant
distance time graph IV
can be used to calculate average speed
distance time graph V
change in distance can be distance by change in time
distance formula II
distance= speed times time/ d- s * t
time formula
time = distance divided by speed;
t = s/t
speed formula
speed = distance divided by time;
s = d/t
