What is called negative accelarration?
Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
Difference between positive and negative acceleration?
when velocity is increasing,accleration is positiveand when velocity is decreasing,accleration is said to be negative.
Explain how positive and negative acceleration affect motion?
when the acceleration of the body is positive its mean that its velocity is increasing and the speed of the motion also increases and speed will decrease when acceleration is negative.
Can a body have negative velocity and positive acceleration?
no a body can only have positive velocity .sometimes it have negative acceleration
What is positive acceleration?
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
What is the difference between negative and positive acceleration?
Positive acceleration means the magnitude of velocity is increasing,i.e. something is speeding up.Negative acceleration means the magnitude of velocity is decreasing,i.e. something is slowing down.
What is positive accelerations?
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
Can the velocity of an object be positive and acceleration negative?
Yes. An object slowing down but still moving in a positive direction has a positive velocity but a negative acceleration.
Can an object have increasing velocity and decreasing acceleration?
Yes, decreasing acceleration could still be positive, which yields an increase in velocity (speed). Velocity is the rate of change of position, and acceleration is the rate of change of velocity. As long as the acceleration is positive, then velocity is increasing. If acceleration becomes negative, then velocity is decreasing. ======================= I second that accelerated motion ! Even if the acceleration is petering out, as long as it's still more than zero, the speed can be increasing. By the way ... you can have a big solid acceleration, and it doesn't mean that the speed or the size of the velocity has to be increasing. Or even changing. But that's another story.
Can the acceleration of an object be negative when its velocity is positive?
no
How many types of changes are there in velocity?
Velocity can either increase or decrease. It can do so at either an increasing or decreasing rate (positive or negative acceleration)
If the acceleration is increasing with time will the velocity graph be a straight line concave up or concave down?
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.
