Distance and Distance Formula

Help with Distance

Let the least distance covered by a body in uniform motion from A to B along the straight line joining AB be 100 km. In this numerical value of displacement and distance travelled is 100 km. If the body takes 2 hours to cover this distance, the speed of the body is 50 km/hr. The velocity of the body from A to B is 50 km/hr. Numerically speed and velocity are same. Please observe that direction has not been indicated in the case of speed. Whereas it is indicated in the case of velocity.

Example: Let the least distance between A and B be 100 km as shown in the. A body travels from A to B along the straight line joining A and B. Let this body cover a distance of 20 km in the first half hour, 40 km in second half hour, 25 km in third half hour and 15 km in the fourth half hour. Even in this case the distance travelled and the displacement of the body is numerically equal. The average speed of the body is 50 km/hr. Let us consider a body travelling along the path from A to B. If the distance it travels is 100 km and the time taken is 2 hrs, then the speed is 50 km/hr. In this example the speed and velocity are not numerically equal. Let the least distance between A and B be 25 km. The displacement of the body is only 25 km from A to B. Therefore the average velocity becomes 12 km/hr. Let us now consider that the object is in uniform motion along the curved path. Even then we cannot say that the body is moving with uniform velocity. This is because the body is changing its direction continuously along its path. Therefore an object is said to be moving with uniform velocity, if it does not change its direction and the distance it travels in unit time. Hence the average velocity is stated to be 12 km/hr in the above.

Help with Distance Formula

The distance formula is feathering the deviation between a1, a2 and b1, b2 may ensure the resolution is invariably positive. Subtraction is not really commutative. Instance of a typical slope formula is when one multiplies the numerator plus denominator by -1. The distance formula is utilized to get the length between the coordinate points. The distance is invariably monitored and measured in models such as meters, centimeters and kilometers. This unique formula is required in the calculation at the time of figuring out the length or distance. Distance Formula: For learning distance, this formula is really significant. Precisely the pickings associated with a lesser amount off all greater of the similar form or denomination, it is also known as a procedure for finding out the deviation between two quantities.
