formulas
Formula for displacement
d2-d1= displacement
what is the difference between speed and velocity?
speed is the time of rate of a moving object, on the other hand, velocity is the rate and direction of a moving object.
the "x" axis normally shows what?
Time in which it took the object to go from one place to another.
A car gps shows what
shows how long it takes to get somewhere and what the distance would be.
The "0" is placed were in the average graph?
bottom left corner to symbolize zero for both time and distance.
Formula for speed (V)
d / t = v
Luke skateboard's to his friends house at 15 km/h, the friend lives 30 km, away how long will it take to his friends house?
speed = 15 distance = 30 time =?
d / v = t
30 / 15 =2
time = 2
straight lines on a P-t graph symbolize what?
uniform velocity (speed and direction stay the same)
what will a car with gps show you?
speed, trip distance, distance to destination.
what variable does the x-axis show?
the independent variable which is the one variable that is purposely going through change.
Formula for time (T)
d / v = t
Suzie rides a scooter at a speed of 15 km/h. If she travels for two hours, how far does she go?
15 = v 2 = time d=?
(15) (2)= 30
30 = d
what happens when two objects interact?
the forces they exert on each other are equal and oppsite.
the velocity calculated by gps software was approximately two miles per hour slower then that of calibrated speedometer.
If someone was walking according to a position time graph what would symbolize them walking backward?
A downwards line would symbolize walking backwards or back towards a beginning spot.
Formula for distance
(V) (T) = d
Speed is calculated as the what?
The total distance travelled over the total time it took to travel.
a bus travels from town a to town b, covering displacement of 240 kilometres west 3 hours
the buses velocity would be 80km/h west.
what information does a slope on a distance time graph provide?
The amount of time it took to get to the point.
Formula for velocity
displacement / time = velocity
The bus with the velocity of 20 m/s travelled for 60 seconds, what was the displacement?
(velocity) (time) = displacement
(20) (60) = 1200m/s
Sarah bikes covers a displacement of 40 kilometers to east in 2 hours.
Sarahs velocity is 20km/h
When more than one object is being plotted on a time graph how do you know which one is going faster without calculating the slope of each line?
By which one started and ended at what time.
