Displacement

from class:

Calculus I

Definition

Displacement is the net change in position of an object, calculated as the difference between the final and initial positions. It can be determined using definite integrals in calculus.

congrats on reading the definition of displacement. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. Displacement is a vector quantity, having both magnitude and direction.
  2. The definite integral of a velocity function over a given interval gives the displacement.
  3. If \( s(t) \) represents the position function, then displacement from \( t = a \) to \( t = b \) is \( s(b) - s(a) \).
  4. The Net Change Theorem states that the integral of a rate of change (like velocity) gives the net change (like displacement).
  5. In certain contexts, displacement can be zero even if distance traveled is not, due to returning to the initial position.

Review Questions

  • How do you calculate displacement using an integral?
  • What is the difference between displacement and distance traveled?
