Yes, all a negative acceleration means is the object is slowing down.
no a body can only have positive velocity .sometimes it have negative acceleration
no because acceleration can be negative due to decreasing of velocity so its not possible
Yes. An object slowing down but still moving in a positive direction has a positive velocity but a negative acceleration.
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
Yes. Imagine a ball on a rigid pole being swung around, and slowing down. It's tangential velocity is positive but it's tangential acceleration is negative
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
No. Acceleration is Delta-Velocity / Delta-Time. If Acceleration is negative then that means that either Delta Velocity is negative or Delta Time is negative---which is not practical. For Acceleartion to be negative, that means the Velocity has to Decrease. (where Delta Velocity is change in Velocity or V2 - V1)
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
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.
Yes, velocity is the integral of acceleration and their signs at any given time are independent.
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.
It cannot have negative velocity, it can have negative acceleration.
Acceleration and deceleration are related by their their sign. Acceleration is positive ( increase in velocity with time) and deceleration is negative (decrease in velocity with time).
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.
Restate the question: When are acceleration and velocity pointing in the opposite direction? If you are going forward but slowing down, then the velocity is positive, but the acceleration is negative.
when velocity is increasing,accleration is positiveand when velocity is decreasing,accleration is said to be negative.
Snowboarding demonstrates speed, velocity, and acceleration. It can also demonstrate a positive or negative value for velocity and 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.
Yes. A car that brakes is slowing down and therefore has negative acceleration, but is still moving forward a therefore has positive velocity because it cant all of a sudden stop.
it will stop after some time
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
