Acceleration is a change in speed or direction. Acceleration like most variables in science is a quaternion, consisting of a real part and a vector part, a=ar + av.Unfortunately, our education system has not caught up to this fact and most students don't get to study vectors and hardly any get to study quaternions. An example of the real and vector acceleration is given in Gravity.
The gravitational energy is E=-GmM/r + mcV= -mu/r + mcV, the force of gravity is
F=(mv^2/r - mcv/r cos(x)) + (dmcV/cdt + Del x mcV - Del mu/r).
The acceleration is:
a= f/m= (v^2/r -cv/r cos(x)) + (dV/dt + cv/r sin(x)T' + v^2/r R/r)
The first parenthesis gives the real part of acceleration and the second parenthesis gives the vector part of acceleration. V^2/r is the centripetal acceleration and -cv/r cos(x) is the centrifugal acceleration.
A change in speed or direction is caused by a force and is called acceleration.
Acceleration
Acceleration in motion refers to a change in speed or direction of that object's motion. So a type of motion in which speed and direction do not change is a motion in which the acceleration is constant (i.e. unchanging).
of Accelerate
To change the acceleration of a car: speed up, slow down or turn. Acceleration is any change in velocity. Velocity is "how fast" and in "what direction". To speed up is to accelerate (increase the velocity). To slow down is to deaccelerate (decrease the velocity) To turn is also a form of acceleration (changes the direction of the velocity).
A change in speed (and/or direction) is acceleration.
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
Acceleration is the time rate of change of speed. Acceleration = speed/time.
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
Motion is about speed of location change, acceleration is about speed change.
By definition acceleration is the change in velocity (speed).
Acceleration = (change in speed) divided by (time for the change)
Acceleration is the rate of change of speed, so if speed is constant, acceleration is zero. However, if speed is constant but direction is changing (e.g. moving in a circle at constant speed), the velocity is changing, and thus there is still acceleration.
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
Acceleration measures the change in speed
Yes. Acceleration is change in velocity. Velocity is either change in speed or change in direction. If you fix the speed, change in direction can account for change in velocity, i.e. acceleration.
