What is the word and symbol equation for calculating average speed?
average speed = distance travelled/time taken
v= delta x/delta t
In a distance - time graph what is represented by a horizontal straight line?
A stationary object
In a distance - time graph a straight sloping line represents what?
An object moving at a constant speed
In a distance - time graph the gradient is equal to what?
The speed of the object
What type of quantity is displacement?
A vector quantity
What is the word and the symbol equation for calculating average velocity?
average velocity = change in displacement/time taken
v=delta s/delta t
Acceleration is defined as …
the rate of change of velocity
In a velocity - time graph a straight horizontal line represents what?
a constant velocity
How do you calculate acceleration from a velocity - time graphs?
By working out the gradient
In a velocity-time graph what does a curved line mean?
A changing velocity
What are the 4 suvat equations?
