Distance and Displacement in Physics: Understanding Motion
This video explains the difference between distance and displacement in physics, using the example of a person's movement.
00:00:00 This video explains the difference between distance and displacement in physics, using the example of a person's movement. Distance is the total length traveled, while displacement is the straight-line distance from start to end.
📏 Distance is the total scalar length of the actual path that an object moved, measured in meters.
➡️ Displacement is a vector that points from where the object started to where it ended, regardless of the specific path taken, also measured in meters.
🚶♂️ An example is given with a person's movement, where the total distance traveled is 9 meters while the displacement is 3 meters to the right.
00:01:03 The video explains the concepts of distance and displacement in Physics using simple examples. It demonstrates how to calculate displacement using the Pythagorean theorem.
📏 Displacement is the change in position of an object and includes both magnitude and direction.
🔺 To find displacement, we can use the Pythagorean theorem to calculate the length of the straight line connecting the initial and final positions.
🗺️ Distance is the total path traveled by an object and only considers magnitude.
00:02:07 Understanding distance and displacement in physics. Distance can be larger or equal to displacement, but never smaller. Displacement is the change in position from the starting point.
📏 Distance is the total length traveled, while displacement is the straight-line distance between the starting and ending points.
➡️ Distance can be larger than or equal to displacement, but it can never be smaller.
⬆️⬇️ When dealing with motion on an axis, a zero point and positive/negative directions need to be defined.
00:03:09 The video explains the concepts of distance and displacement in physics, demonstrating how they can be positive or negative based on direction. Displacement is negative when moving in the opposite direction, while distance is always positive.
📏 Distance and displacement are arbitrary in terms of direction and zero point.
➕ For positive displacement, the object moves in the positive direction.
➖ For negative displacement, the object moves in the negative direction.
00:04:14 Learn the difference between distance and displacement in physics and how they are calculated by adding or subtracting motions. Positive and negative directions can be switched without changing the results.
📏 Distance is the total length traveled, which is always positive.
🚶♂️ Displacement is the straight-line distance between the starting and ending points, which can be positive or negative.
🔃 Displacement can add or subtract based on the direction of movement.
00:05:17 Understanding the concepts of distance and displacement to describe motion using symbols.
📏 Distance and displacement are two different concepts used to describe the motion of an object.
⬆️ Distance is a scalar quantity that represents the length of the path traveled by an object.
⇄ Displacement is a vector quantity that represents the change in position of an object, taking into account both the distance and the direction traveled.
