You can get speed or velocity by dividing distance moved, by the time it takes to move that distance.

What is formulas finding speed and velocity?
velocity = distance / time There are also some formulae involving acceleration; for example, in the case of constant acceleration: velocity = initial velocity + acceleration x time If the acceleration is not constant, an integral is used instead.
If you increase the radius of circular motion then what is the centripetal acceleration?
That depends what you will remain constant: the angular velocity, or the speed. Here are two formulae that can help you decide: acceleration = speed squared / radius, and acceleration = angular velocity squared times radius. Angular speed should be measured in radians in this case. Angular speed is equal to 2 x pi x (revolutions per second). From the above formulae, it clearly follows that: (a) If you maintain the speed constant (and thereby reduce angular speed, a larger radius means less centripetal acceleration. (b) If you maintain the angular speed constant (and thereby increase the speed), a larger radius means more centripetal acceleration.
How do you calculate the speed of a ball during free fall from 55m high?
Using one of the formulae for constant acceleration: vf2 = vi2 + 2as, where vf is the final velocity, vi is the initial velocity (omit this term in this case, since the initial velocity is zero), a is the acceleration (9.8 in this case), and s is the distance.
What is the formula in calculating time acceleration final velocity and initial velocity?
There are different formulae for calculating these variables which depend on what information is available.
What is the biggest difference between speed and velocity?
velocity is speed with direction; velocity is a vector and speed is a scalar
What is the formula for time in speed?
Such formulae are usually given for acceleration; NOT for speed. The relevant formula is:a = dv/dt That means, acceleration is the rate of change of velocity, with respect to time. For constant acceleration (or for short time intervals), you can also write this as: a = delta v / delta t (change in velocity divided by the time interval)
What is speed in a given direction is called?
Speed in a given direction is velocity.
Is velocity the speed of a wave?
Velocity and speed are not synonyms.
Diffetiate speed and velocity?
Speed has no direction, velocity does.
Are speed and velocity different?
SPEED has the speed only; while VELOCITY has the direction and the speed.
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
What is the Formula for (change in speed)time?
Such formulae are usually given for acceleration; NOT for speed. The relevant formula is:a = dv/dt That means, acceleration is the rate of change of velocity, with respect to time. For constant acceleration (or for short time intervals), you can also write this as: a = delta v / delta t (change in velocity divided by the time interval)
