What is the primary difference between distance and displacement?
Distance is a scalar quantity, while displacement is a vector quantity.
Distance measures the straight line between two points, while displacement measures the total path traveled.
Distance can be negative, while displacement is always positive.
Displacement is always longer than the distance.

The rate of change of speed.
What is acceleration?
The rate of change of velocity.
The rate of change of speed.
The total distance traveled divided by time.
