Distance, Displacement, Speed, Velocity And Acceleration Flashcards
How do you check what value is displacement and what value is distance
Displacement will always be shorter than or equal to distance
What is the formula for speed
V = △x/ △t = xf - xi/ tf - ti
What is the unit of speed
m.s^-1
What type of quantity is speed
A scalar quantity
What is the formula for velocity
V (arrow on top) = △x / △t
What is the unit for velocity
M.s^-1 + direction
What you of quantity is velocity
Vector quantity
What is the formula for average speed
Average speed = total distance/ total time
What is the formula for average velocity
Average velocity = total displacement / total time
What is the formula for distance
X (with arrow on top) = x1 + x2 + x3
What is the formula for acceleration
a = △v/ △t
What is the unit for acceleration
M.s^-2 + direction
What does a positive acceleration mean
Means speeding up, object still moving In the same direction
What does a negative acceleration mean
Means slowing down, object is still moving in the same direction
What are the three types of motion graphs
Position time graphs, velocity time graphs and acceleration time graphs
Learn position graph shapes and their meanings
Did you get it right ?
Learn velocity time graphs and their meanings
Did you get it right ?
Learn acceleration time graphs and their meanings
Did you get it right ? (Acceleration graphs for now can only be horizontal lines) 
What values can you get from a position time graph and how
Gradient = velocity = △x/ △t
What values can you get from a velocity time graph and how
Gradient = acceleration = △v/ △t
And
Area under graph = distance = lxb + 1/2bh
What values can you get from an acceleration time graph and how
Area under graph = velocity = lxb
What are the three equations of motion
△x = Vi △ t+ 1/2a △t^2 (no Vf)
Vf^2 = Vi^2 + 2a △x (no △t)
Vf = Vi + a △t (no △x)
What is the frequency in ticket timers
The number of dots made in 1s
How to get T in ticked timers
T = 1/f
What is T in ticket timers
The amount of time (s) it takes to make one dot
How to get f in ticket timers
f = 1/T
Look at the different ticket timers and state what they mean in terms of velocity

How to get from m/s to km/h
Multiply by 3,6
