While you are standing on your front porch, you decided to walk to the end of your driveway, 10 meters away, and back to your front porch, what is your distance traveled and what is your displacement?

Distance travelled: 20meters

Displacement: 10 meters.

Explanation:

In geometry and mechanics, a displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion. It quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory. A displacement may be identified with the translation that maps the initial position to the final position.

explanation:

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
