# Position / Displacement

An object's position is its location at a given point in time

Position and displacement are both vectors

# Average Speed

Average speed is the distance traveled divided by the time interval

Average speed is a scalar, and is measured in meters/second

# Average Velocity

Velocity is the rate at which position changes.

Average velocity is the displacement during a time interval divided by the time interval

Average velocity is a vector, and is also measured in meter/second

# Acceleration

Acceleration is the rate at which velocity changes

Acceleration is a vector

Units are m/s

^{2}

# The Position Vector

# Average Velocity

# Instantaneous Velocity

Average velocity observed over an infinitely small time interval provides instantons velocity

Instantaneous velocity is the derivative of position with respect to time

Area under the velocity-time graph is the displacement during that time interval

# Acceleration

Acceleration is the rate at which velocity changes
