Homework Statement
A child rides on a pony around a circular track with a radius of 4.5 meters.
Homework Equations
What is her distance traveled and displacement after she has gone half way around the track?
Distance is the total length traveled by an object, while displacement is the straight-line distance from the starting point to the ending point.
Displacement is calculated by finding the difference between the final position and the initial position of an object. It is represented by the symbol Δx, which is the change in position along the x-axis.
No, distance and displacement can be equal if the object travels in a straight line from the starting point to the ending point. However, in most cases, distance is greater than displacement since it takes into account the total path traveled.
Yes, displacement can be negative if the object moves in the negative direction along the chosen coordinate system. Positive displacement indicates movement in the positive direction.
The Pythagorean theorem can be used to calculate the displacement of an object if it travels in a straight line. By using the theorem, the displacement can be found by taking the square root of the sum of the square of the horizontal and vertical displacement.
