Speed Distance Time Flashcards
How to calculate speed, distance and time
Units of speed
M/s or km/hr
Meters in a kilometre and seconds in a Minuit
100meters = 1 kilometre
60 seconds =1 minute
Equipment for car experiment
Ramp, metre ruler x2, stopwatch, toy car, clamp stand
Controlled variables for car experiment
Ramp height, surface, release point and starting from 0m/s

Acceleration speed time graph
What are distance time graphs used for
Show how far something travels in a certain amount of time
Finish these sentences for distance time graphs…
The steeper the line…
Horizontal line shows…
A straight diagonal line shows….
The faster the object is moving.
It has stopped.
The object is moving at a constant speed.
Just a picture of a distance time graph
What can speed time graphs be used for
Describing the movement of an object.
We can use them to see if an object is moving at any point in time and also to see the speed it’s travelling at.
At zero.
Flat straight line.
Diagonal straight line.
Fins the acceleration, deceleration and distance
