sense acceleration

When you watch the MotoGP race, consider the speed racer when in a straight line. When in a straight line, the riders moving at faster and faster. However, while in turn, reduces the rate of motorcycle riders. What do you call this velocity addition and subtraction? Find the answer below.
1. Definition of Acceleration
In everyday life, we are always moving from one place to another. As explained before, when moving from one place to another, we have a certain speed. For example, when going to school, you go to a certain speed. You can run slow, fast, or slow sometimes fast sometimes. If you are running faster and faster, meaning you are accelerating. Meanwhile, if running more and more slowly, meaning you are experiencing a slowdown. From the explanation of acceleration and deceleration, there is one thing that connects the two, namely the change of pace. So, deceleration and acceleration are essentially the same, which indicates a change of pace every time. The difference between the acceleration and deceleration lies in its direction. Deceleration direction opposite to the direction of acceleration. Thus, the acceleration (acceleration) is the rate of change of velocity with respect to time. A moving object has acceleration berubahubah. Thus, we can not precisely calculate acceleration. That we can count is instantaneous acceleration of the object.
2. Acceleration Momentary
Suppose that at t1 an object that was in A is moving at a speed v1. At time t2 the next, he was on point B with velocity v2. Acceleration of the object during the move from A to B is defined as the change in velocity divided by the time interval. Acceleration experienced by the object to be written by the equation:
acceleration = change in velocity / time interval = (v2 - v1) / (t2 - t1) = Δv / Δt
Description:
a = acceleration (m/s2)
v1 = initial velocity (m / s)
v2 = final velocity (m / s)
t1 = initial time / initial (s)
t2 = end time (s)
from the equation, if v2> v1, Nili acceleration is positive, the direction of the acceleration in the direction of the acceleration of the object. if v2 <v1, Nili negative acceleration, acceleration direction opposite to the acceleration of the object. Negative acceleration motion of the object is slowing pengalamani. How do we calculate the acceleration in a very short time interval (Δt → 0)? Acceleration of the object at very short time intervals is called instantaneous acceleration. To calculate the instantaneous acceleration, we can use the following equation:
asesaat = dv / dt
