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.
Does acceleration mean that a moving object is decelerating?
No, acceleration refers to a change in an object's velocity, which can either be a speed up (positive acceleration) or a slow down (negative acceleration or deceleration). If an object is decelerating, its velocity is decreasing over time.
If velocity is positive which would most likely yield a negative acceleration?
If an object is moving in the positive direction, a negative acceleration would most likely occur if the object is slowing down, such as when it is decelerating or coming to a stop. Negative acceleration indicates that the object's velocity is decreasing over time.
What happens when velocity is negative and acceleration is positive?
When velocity is negative and acceleration is positive, the object is moving in the negative direction and its speed is increasing. This means that the object is slowing down as it moves in the negative direction - essentially decelerating.
The speed of a car moving on a straight road is decreasing on applying the brakes its velocity and acceleration are in same direction?
If the speed of the car is decreasing while the car is still moving in a straight line, this means that the velocity and acceleration are in the same direction. This is because the car is decelerating, which results in a negative acceleration in the same direction as the velocity. This negative acceleration causes the speed of the car to decrease over time.
A negative slope on the velocity vs. time graph indicates that the object is not accelerating.?
Actually, a negative slope on a velocity vs. time graph indicates that the object is decelerating or moving in the opposite direction. If the slope is constant, the object is moving at a constant velocity.
A classmate in the physics state that the negative acceleration always mean that a moving object is decelerating is that true?
No, that statement is not entirely true. Negative acceleration means the velocity of the object is decreasing, which could be due to deceleration (slowing down) or changing direction. Positive acceleration means the velocity is increasing.
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 an object's acceleration if its moving at 30 miles per second and comes to a stop in 5 s?
The object's acceleration is -6 miles per second squared. It is negative because the object is decelerating, or slowing down. The negative sign indicates the acceleration is in the opposite direction of the object's initial velocity.
Can the velocity of an object be negitive when its acceleration is positive?
That just means that the velocity and acceleration are in oppposite directions ... exactly the situation when a car is slowing down for a stop, or a ball is tossed upward and hasn't reached the peak yet.
What is a moving object that has a velocity vector and acceleration vector in the opposite direction?
An object with a velocity vector and acceleration vector in opposite directions is a decelerating object. This means the object is moving in a specific direction but slowing down.
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.
It is physically impossible for an object to have a negative acceleration and yet be speeding up?
An object with a negative acceleration is slowing down, not speeding up. Negative acceleration means the object is decelerating or moving in the opposite direction of its velocity, causing it to slow down. Objects speed up when their acceleration is in the same direction as their velocity.
