One Dimensional Motion Flashcards
1
Q
Distance
A
Total area travelled by an object
xi + xf
2
Q
Displacement
A
Change in position of an object
xf - xi
3
Q
Speed
A
The total distance travelled divided by the time taken by an object.
s = x/t
4
Q
Velocity
A
The displacement divided by the time taken by an object.
v = Δx/t
5
Q
Instantaneous speed
A
It is the speed of an object in a given time interval.
s = x/Δt
6
Q
Instantaneous velocity
A
It is the velocity of an object in a given time interval.
v = Δx/Δt
7
Q
Acceleration
A
The change in velocity of an object over time taken.
a = Δv/t
Another equation for acceleration is F = ma
8
Q
Kinematic equations
A
v = vi + at Δx = vit + at^2/2 Δx = (v + vi/2)t^2 v^2 = vi^2 + 2aΔx
