Speed is a measure of motion and velocity just includes what direction it happens in.
Acceleration is a measure of changes in speed.

What is the different between velocity and acceleration?

Velocity . . . what speed and direction something is moving. Acceleration . . . how fast the speed and/or direction of its motion are changing.


What is the relationship between radius and velocity in circular motion?

None of them depend directly on the other. However, centripetal acceleration can be calculated as a = v2/r.


What is the difference between uniform motion and constant acceleration?

"Uniform motion" means constant velocity ... constant speed in a straight line. "Acceleration" means any change in velocity ... speed or direction. So 'uniform motion' means zero acceleration.


Is there is any linear or Circular motion equation or just the motion in which acceleration of body changes at constant velocity?

The question is, if not a maelstrom, certainly a melange at least.Especially noteworthy is the part where "acceleration of a body changesat constant velocity".Acceleration is the rate of change of velocity. If velocity is constant, then there isno acceleration. If velocity changes at a constant rate, then acceleration is constant.Velocity would have to change at a rate that changes, in order to have a changingacceleration.Now, what is it you're looking for ? A "linear or circular motion equation" ? There areoodles of them, describing the relationship among the position, displacement, speed,velocity, and acceleration, in one, two, or three dimensions, in rectangular, polar, andspherical coordinates, for linear motion, and an entire separate set of equations forcircular motion.


What is acceleration in science?

Acceleration is any change in velocity. Velocity is the speed and direction of motion.


Which two variables show a INVERSE relationship?

For an object in motion without any acceleration, velocity and time.


How is velocity of zero different from an accerlation at zero?

Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.


How are motion and acceleration different?

In Simple motion, there is no force being applied. The moving object moves in a straight line with constant velocity. In acceleration, there is a force applied. The object's velocity is changing. The first derivative of acceleration is velocity. The first derivative of velocity is distance. (Derivative is a calculus thing.)


Newtons second law of motion?

the second law of motion states the relationship between force, mass and acceleration. acceleration= force/mass



What is the definition of motion graph?

Constant acceleration motion can be characterized by motion equations and by motion graphs. The graphs of distance, velocity and acceleration as functions.



Which decides direction velocity or acceleration?

The sign on velocity indicates the direction of motion.


What is Motion without acceleration?

Constant velocity including the constant zero velocity.


How does positive acceleration and negative acceleration affect motion?

positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.


What is the relationship between force and acceleration?

The relationship between force and acceleration mathematically is proportional, as seen in the second low of motion F = m*a. The acceleration of an object will be equal to the ratio of the net force on the object to the mass.


What is the equation for motion?

Which one SPEED? VELOCITY? ACCELERATION ?...




What is the relationship between force mass and motion?

Force = mass * acceleration or F = ma.


What is a example of Newtons 2nd law?

Newton's second law of motion, which states that force is equal to mass multiplied by acceleration, represents the relationship between force and change in velocity, or acceleration. The force then depends greatly on the change in velocity. When there is a change in the object's velocity or momentum, it is because it was accelerated or de-accelerated (change in velocity) due to some external force. This force would be equal to the mass of the object multiplied by the change in velocity (acceleration).


Can an object accelerate if its velocity is constant?

No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.


How does acceleration affect motion in the same direction?

It will increase the velocity of the the object in which the acceleration is applied.


Is motion with constant velocity an example of motion with constant acceleration?

Well, technically yes, and we even know the magnitude of the constant acceleration.If velocity is constant, that tells you that acceleration is zero, which sounds likea constant to us.
