Calculate its velocity?Īnswer) Displacement S = 1000 km = 1000 × 103 m, Therefore, Velocity Formula = S/t = (500 × 103)/3600 = 139 m/s.Ī car moves the distance of 1000 Km in 1 hr. Calculate its velocity?Īnswer) Displacement S = 500 km = 500 × 103 m, R = Equals the distance from the center of the mass.Ī plane moves the distance of 500 Km in 1 hr. M = Mass of the body/object to be escaped from. Where, G = universal gravitational constant = 6.67410-11Nm2/kg2 The unit for velocity is meters per second (meter/second). Velocity has a magnitude (a value) as well as a direction. So, it can be defined as the change in the position of an object, divided by time.

Velocity is a measure of how quickly any given object moves. In any numerical, if any of these two quantities are given we can easily calculate the missing quantity by making use of this formula. The units of Velocity are meters/second or m/s. Since we convey displacement in meters and time taken in seconds.

It is represented by the letter V and velocity can be calculated as Average velocity is defined to be the change in position divided by the time taken to travel that distance.

You know that a large displacement in a small amount of time means a large velocity and that velocity has units of distance divided by time, for example, miles per hour or kilometers per hour. Your notion of velocity is probably similar to the scientific definition of velocity. For example, if the train leaves Penn Station in New York at 2 pm and you know how fast the train travels north, you can predict when it will arrive at South Station in Boston. Velocity makes it possible to create travel timetables, a common form of physics problem assigned to students. The actual use of velocity does not end there, but one of the most common reasons for measuring speed is to determine how fast you (or anything you move) will get to the point from somewhere. Velocity measures movement from one place to another. Other units include miles per hour (mph), kilometres per hour (kph), and kilometres per second (km / s). SI (international) units at velocity are m / s (meters per second), but the velocity can be expressed in any unit of distance at a time. You can calculate speed using a simple formula that includes measurement, distance, and time. In terms of calculations, speed is the first exit of a position in terms of time. As you might guess, the scalar size (total value) of vector velocity is the speed of movement. The speed of the car heading north on the main highway and the speed of the rocket exploding in space can both be measured using speed. Simply put, velocity is the speed at which an object moves in one direction. Velocity is defined as the vector measure of level and direction of movement.
