To determine the displacement of an object, you only have to consider the change in position between the starting point and the ending point. The path followed from one point to the other does not matter.
4.6 One Dimensional Kinematics and Integration. When the acceleration a(t) of an object is a non-constant function of time, we would like to determine the time dependence of the position function x(t) and the x -component of the velocity v(t) . Because the acceleration is non-constant we no longer can use Eqs.
To answer this question we need to know two things: the distance around Pluto’s equator and the crawling speed of a mauve caterpillar. Since we are provided with the radius of Pluto in the question, we can calculate the distance via the formula 2ˇr. The crawling speed of a mauve caterpillar, however, is considerably more di cult to nd.
distance covered in each interval and the total distance covered by two methods: 1) Calculation of the area under the line R( P); 2) Using the formula for the distance in the motion with constant acceleration.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
For example, we may want to determine the speed of light, which we can calculate by dividing the distance a known ray of light propagates over its travel time,
