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.
the answer is Velocity the answer is inertia
Acceleration is the rate at which velocity changes. (Not speed.)
rate of change of velocity
Direction.
velocity
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 a measure of how quickly the speed of an object changes over time, not the speed itself. Speed refers to the rate at which an object covers distance, while acceleration refers to how the speed of the object changes. So, acceleration is not a kind of speed, but rather a measure of how speed changes.
Constant speed means moving at a steady rate without any change in velocity, while constant acceleration means changing the velocity by the same amount in each unit of time. In other words, constant speed is uniform motion, while constant acceleration is when the velocity is changing at a constant rate.
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)
Speed is a scalar quantity that represents the rate at which an object is moving, while acceleration is a vector quantity that represents the rate of change of an object's velocity. Acceleration can affect the speed of an object by either increasing or decreasing it, depending on whether the acceleration is in the same direction as the object's motion or in the opposite direction. In general, the greater the acceleration, the faster an object's speed will change.
A change in speed is a change in velocity - so, a change in speed is an example of acceleration! Acceleration may be positive or negative. Negative acceleration is sometimes called deceleration. When a force acts on an object; it may change the object's acceleration (speed, direction, or both).
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
