![]() ![]() Next time you are out walking, imagine you are still and it is the world that moves under your feet. The calculator can be used to solve for s, u, a or t. 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. 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. Acceleration Calculator is a free online tool that calculates the acceleration of an object effortlessly and quickly by taking the initial velocity, final velocity and time. Yes, the velocity is zero as you ended up where you started. 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? Example: You walk from home to the shop in 100 seconds, what is your speed and what is your velocity? ![]()
