What is the negative acceleration?
Negative acceleration is the state of a body whose velocity in a specified direction is becoming smaller. If you apply the brakes while driving a car, the car (and you) will undergo negative acceleration in the direction in which the car was moving.
Would you consider a car turning around a corner at a constant speed to be accelerating?
It depends on which direction you are resolving the acceleration from. If you use the original direction of the car as it turns it is decelerating as the speed it is moving in that direction is decreasing. If you resolve from the direction which the car will be going towards then it is accelerating as its speed in that direction is increasing.
What would the acceleration of a turtle that is moving with a constant velocity of 0.25 miles per second to the right?
The acceleration would be zero because the turtle is moving at a constant speed
What then can you say about the acceleration of the moving car?
The answer depends on when "then" is.
How is an object moving if a slanted straight line on a speed versus time graph represent its motion?
If its slanted up its accelerating, if down its decelerating.
A classmate in the physics state that the negative acceleration always mean that a moving object is decelerating is that true?
It is not true. It means that the object MIGHT be decelerating but not "always" (as your friend says). Instead, think of it this way... We start by clarifying that there is no such thing as "negative acceleration" per se. That is, that acceleration is a vector composed of an absolute value scalar and a direction. So "negative acceleration" actually refers to an acceleration which just happens to be in the negative direction of whatever coordinate system you've chosen to define for the particular problem. We define a coordinate system (for a two dimensional universe to keep things simple) with positve/negative x and y. If the object starts out already moving in the positive X direction, then to apply an acceleration in the negative direction would mean there is deceleration. If the object is stationary or moving in the negative X direction, then applying an acceleration in the negative X direction would actually be accelerating the object. In other words, the reference from has to stay constant for there to be meaningful discourse on the subject. By the same note, even moving in the positive X direction, if the object is acclerated in the negative Y direction then the object is actually accelerating.
True or false Negative acceleration always means that a system is slowing down?
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
What is deceleration in physics?
'Acceleration' is defined as the rate of change in velocity and the direction of the change. 'Deceleration' is a popular but unscientific word used to describe acceleration with a negative magnitude, i.e. 'slowing down' without regard for its direction.
Is it possible that speed is zero while the acceleration is non -zero?
Yes. You could be moving left with an acceleration to the right (decelerating) and come to a stop before you begin to move to the right.
Can acceleration ever be negative?
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
How is a negative acceleration different from a positive acceleration?
Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.
When a moving object experiences a negative acceleration?
change in matter
What is the negative acceleration?
Negative acceleration is the state of a body whose velocity in a specified direction is becoming smaller. If you apply the brakes while driving a car, the car (and you) will undergo negative acceleration in the direction in which the car was moving.
Is acceleration the change of speed and or direction of an object?
These two cases are represented by "positive" acceleration. The opposite cases (slowing down in the positive direction or speeding up in the negative direction) are represented by "negative" acceleration.
Meaning of decelerating?
Decelerating means to slow down. It means that an object is moving at an increasingly slower speed.
When a body moving with uniform and negative acceleration?
When the body is in simple hermonic motion
What is the direction of the acceleration of an object that is slowing down while heading northward?
The acceleration is opposite the direction the object is moving, so the acceleration is negative and southward.
