![]() Next time you are out walking, imagine you are still and it is the world that moves under your feet. ![]() ![]() Table 1.5 DIFFERENCES BETWEEN VELOCITY AND. In order to calculate velocity, we use this formula: Velocity change in distance. VELOCITY The velocity of a body is the distance travelled by it per unit time in a definite direction. Think about this: are you really standing still? You are on planet Earth which is spinning at 40,075 km per day (about 1675 km/h or 465 m/s), and moving around the Sun at about 100,000 km/h, which is itself moving through the Galaxy. The standard used to describe velocity is meters per second or m/s. When we say something is "at rest" or "moving at 4 m/s" we forget to say "in relation to me" or "in relation to the ground", etc. Yes, the velocity is zero as you ended up where you started. It is equal to the displacement of a body in unit time. You can calculate velocity by using a simple formula that includes rate. The velocity of a body is a vector quantity. In calculus terms, velocity is the first derivative of position with respect to time. Velocity = 130 m 100 s East = 1.3 m/s East You forgot your money so you turn around and go back home in 120 more seconds: what is your round-trip speed and velocity? Velocity is defined as: The rate of displacement of a body is called its velocity.The velocity tells us not only the speed of a body but also the direction along which the body is moving. ![]() Example: You walk from home to the shop in 100 seconds, what is your speed and what is your velocity? ![]()
