What is the other name of negative acceleration?
The other name of negative acceleration is “Retardation or Deceleration”.
A deceleration is opposite to the acceleration..
What does it mean if an object has a positive velocity but a negative acceleration?
An object which moves in the positive direction has a positive velocity. … If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).
Why is velocity zero?
Velocity as a Vector Quantity Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity.
What direction is negative velocity?
Velocity comes with direction, it indicates a speed at a direction. If velocity becomes negative, it is that speed in the opposite direction.
Can velocity be negative?
The sign of the velocity depends on the coordinate system chosen to define the position. A positive velocity simply means that the object is moving in the positive direction, as defined by the coordinate system, while a negative velocity means the object is traveling in the other direction.
What is an example of negative velocity?
A car driving towards A will on the other hand decrease its coordinate with time and have a negative velocity.
What happens when velocity is negative and acceleration is negative?
If velocity and acceleration have opposite signs, you slow down. Negative velocity = You move backwards. Negative acceleration = You slow down or you go faster in the backwards direction. … While moving to the right, you would accelerate (the acceleration would be positive, too).
Is time can be negative?
“time” is a method founded by man to record events. … So to conclude this question, you can give negative time as in countdowns, or past events. But there is no such thing as a negative in a chronological time graph, that starts and ends with positive numbers, unless you consider BC as the negative on the line chart.
Can initial velocity be negative?
Negative velocity just means velocity in the opposite direction than what would be positive. From the math point of view, you cannot have “negative velocity” in itself, only “negative velocity in a given direction”. The velocity is a 3-dimension vector, there is no such thing as a positive or negative 3D vector.
What does negative velocity look like on a graph?
The position-time graph shows that the slope is both constant (constant velocity) and negative (negative velocity). The velocity-time graph shows a horizontal line with zero slope (zero acceleration); the line is located in the negative region of the graph (negative velocity).
Is the initial velocity always zero?
We generally consider initial velocity is equal to zero(u=0),only when the object starts from rest. Generally at time (t=0),the initial velocity is zero. When a body starts from rest or it changes it direction of motion,it is called as initial velocity.
