Speed is the rate of motion usually expressed as distance traveled per unit of time.
Velocity is the rate of change of position. Both speed and direction are required. Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease in speed is deceleration. In physics, any increase or decrease in speed or change of direction is referred to as acceleration. For more information, look at: http://en.wikipedia.org/wiki/Speed http://en.wikipedia.org/wiki/Velocity http://en.wikipedia.org/wiki/Acceleration
Acceleration is the rate of change of velocity over time.
One formula that shows this relationship is:
vf=vi +at
where:
* vf = final velocity * vi = initial velocity * a = acceleration * t = time
velocity is the speed at which you are traveling, acceleration is the rate you are increasing or decreasing in velocity.
If you are going at constant velocity, you are not increasing or decreasing speed, therefore your acceleration would be zero.-@mikesbabygurl13@
Force is related to acceleration because F= mass X acceleration. Velocity is speed with a direction included. For example, 35 mph is a speed, but 35mph north is a velocity. Acceleration is the rate at which velocity changes. Say that over the course of 10 seconds, a car goes from zero to 100 meters per second. The car increases its velocity 10 meters per second every second. So the acceleration is 10 meters per second squared. For you Calculus types: Acceleration is the derivitive of velocity with respect to x. Velocity is the integeral of Acceleration with respect to x.
they are all have to do with objects in motion...speed is the rate of motion at any given time;
velocity is the speed of something in a given direction;
acceleration is going faster, slower, or changing directions
Acceleration is the rate of change of velocity.
Velocity is the combination of speed and its direction.
Any change of speed, or direction, or both, is acceleration.
v=u+at
where
v is final velocity
u is initial velocity
a is acceleration
and t is time taken for the journey
Acceleration is the change in velocity ("speed") over time.
Acceleration is the derivative of velocity. In other words, acceleration is the rate at which the velocity is changing.
No. Velocity describes a speed and a direction. Acceleration, on the other hand, is the rate of change of velocity (in symbols: dv/dt); in other words, how fast does the velocity change.
Acceleration is the rate of change of velocity (not speed). Acceleration is the rate of change of velocity over time. Velocity is defined by speed and direction. A satellite orbiting the earth at a constant speed is still accelerating because gravity is making it travel in a circle (or ellipse) and consequently its direction and therefore its velocity is constantly changing.
Speed is (distance covered) divided by (time taken to cover the distance).Velocity is a speed and its direction.Acceleration is any change of velocity.
Acceleration is the change in velocity ("speed") over time.
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.

Speed, velocity, and acceleration all have momentum.
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
what are important speed, velocity and acceleration in several sports
Velocity is speed in a given direction Acceleration is the rate in which you change velocity.
Speed is (distance covered) divided by (time taken to cover the distance).Velocity is a speed and its direction.Acceleration is any change of velocity.
I am not sure exactly but i got something like mass & force, it is directly related to the strength of the force & inversely related to the objects mass.You are right, this is Newton's Second Law of motion.Acceleration describes change of velocity of an object with time. (It's rate of change of velocity.)
In that case, you have all three - speed, acceleration, velocity.
