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
What is the name given to a physical quantity described in both size and direction?
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?
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 standard physical unit for displacement?
What is the alternative equation for calculating the average speed of an object?
(initial speed - final speed) / time taken
(initial speed + final speed) / time taken
(initial speed - final speed) / 2
(initial speed + final speed) / 2
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 following equation is the acceleration equation re-arranged so that 'change in velocity' is the subject.
change in velocity = acceleration / time taken
change in velocity = acceleration x time taken
change in velocity = time taken x acceleration
change in velocity = time taken / acceleration
