Scalar
A quantity which only has magnitude (size)
Vector
something with magnitude and direction
Displacement
How an object position changes
Example of Scalars
Time
length
volume
mass
density
area
speed
energy
Example of vectors
Force
acceleration
displacement
weight
velocity
Initial velocity (u)
Starting speed
Final velocity (v)
Ending or finishing
Acceleration equation
Change in velocity / time
Acceleration unit
m/s squared
Stationary
Not moving staying still
What are distant -time graphs used for?
Can be used to describe the motion of an object and calculate the speed of the object
If distance is measured in metres and time in seconds, what’s the unit?
m/s
If distance is measured in miles and time and hours, what’s the units?
mph
If distance is measured in kilometres and time in hours, what’s the units?
Km/h
Remember to check if u need to convert units for answer
For example
Km ➡️ Meters ÷1000
