Chapters 1 & 2: Important Material & Motion Along a Straight Line

Standard base units

Mass, Length, and Time (kg, m, s)

Derived Units

Combinations of SI base units

Position

an object's distance and direction from a reference point

What does displacement measure?

The distance and direction of an object's change in position from the initial position.

What is included in displacement?

Both magnitude and direction

Magnitude

Size or distance quantity

What is Average Velocity calculated?

Displacement divided by time (need direction)

What is Instantaneous Velocity?

the velocity of an object at a specific point in time

How is Instantaneous Velocity calculated?

It is calculated as the derivative of position with respect to time (d/dt)

Average Speed

total distance divided by time |speed|

Average Acceleration

Change in velocity divided by change in time

What is Instantaneous Acceleration?

The acceleration of an object at a particular instant of time

How is Instantaneous Acceleration calculated?

By deriving the velocity with respect to time (d/dt)
