Speed is a measure of motion and velocity just includes what direction it happens in.
Acceleration is a measure of changes in speed.
The centripetal acceleration is equal to velocity squared over radius. a=v^2/r
Velocity . . . what speed and direction something is moving. Acceleration . . . how fast the speed and/or direction of its motion are changing.
None of them depend directly on the other. However, centripetal acceleration can be calculated as a = v2/r.
"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.
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.
Acceleration is any change in velocity. Velocity is the speed and direction of motion.
For an object in motion without any acceleration, velocity and time.
Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.
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.)
the second law of motion states the relationship between force, mass and acceleration. acceleration= force/mass
It changes velocity.
Constant acceleration motion can be characterized by motion equations and by motion graphs. The graphs of distance, velocity and acceleration as functions.
you are still. motion is at rest.
The sign on velocity indicates the direction of motion.
Constant velocity including the constant zero velocity.
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
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.
Which one SPEED? VELOCITY? ACCELERATION ?...
Force = mass * acceleration or F = ma.
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).
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.
It will increase the velocity of the the object in which the acceleration is applied.
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.
