What is the average speed equation?
average speed = total time / distance travelled
average speed = time taken / total distance
average speed = total distance travelled / time taken
average speed = total distance travelled x time taken
Which units could NOT be used for the speed of an object?
m/s
km/h
s/m
miles per hour
What physical quantity has the unit metre per second squared?
(a)
What is the equation for the acceleration of an object?
change in velocity / time taken
change in time / velocity
change in time x velocity
change in velocity x time taken
What is the symbol equation for acceleration?
a = (v + u) / s
a = (v - u) / t
a = (u - v) / t
a = (u - v) / s
Which of the following equation is the average speed equation re-arranged so that 'time taken' is the subject.
time taken = average speed / distance travelled
time taken = average speed x distance travelled
time taken = distance travelled / average speed
time taken = distance travelled x average speed
Which of the graphs shows that one of runners started 10 yards further ahead of the
other?
In which of the following graphs below are both runners moving at the same speed?
Match the description to the graph:
"The car is stopped."
Match the description to the graph:
"The car is traveling at a constant speed."
Match the description to the graph:
"The speed of the car is decreasing."
