I don't think velocity can be a negative number... Use positive.

Can a speed of a body be negative?
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
How do you find the final velocity if the acceleration is negative?
It depends on what information you have. Also, velocity can be negative - it just means that the object is travelling in the direction opposite to the positive direction for the velocity vector.
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.
Is it possible for velocity to have a negative value?
Yes velocity is a vector that has both speed and direction. So if you are going 30 mph in one direction that may be positive, but if you are going in reverse that may be negative.
Can you have a negative position while having a positive velocity?
Certainly. For example, a pendulum at its left-most position.
Can both the velocity and acceleration be negative?
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.
If displacement is decreasing then velocity is?
If displacement is decreasing, then velocity can be positive, negative, or zero, depending on the direction of motion. If the object is moving in the positive direction, a decreasing displacement may result in a positive velocity. If the object is moving in the negative direction, a decreasing displacement may lead to a negative velocity. If the object is stationary and its displacement is decreasing, the velocity is zero.
What can have positive or negative value depending on the direction of the change in position?
Velocity can have positive or negative value depending on the direction of the change in position. Positive velocity indicates motion in one direction, while negative velocity indicates motion in the opposite direction.
How can you tell if acceleration is positive or negative?
Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
Can the speed of the particle ever be negative if so give an example if not explain why?
No, the speed of a particle cannot be negative. Speed is a scalar quantity and is always positive, representing the magnitude of the velocity of an object. Negative values are used to represent the direction of motion in one-dimensional motion.
Differentiate positive acceleration and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration occurs when an object's velocity is decreasing. Positive acceleration is associated with motion in the direction of velocity, while negative acceleration usually indicates motion in the opposite direction of velocity.
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
What is the physical meaning of a negative average velocity?
A negative average velocity indicates that an object is moving in the opposite direction of the chosen positive direction. For example, a negative average velocity would mean the object is moving left if the positive direction is considered right.
Can a car have negative velocity and positive acceleration at the same time if traveling on a highway?
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.
How do you achieve negative velocity?
Negative velocity is achieved by moving in the opposite direction of the positive direction. For example, if a car is moving eastwards with a velocity of 50 km/h, to achieve negative velocity, it would need to be moving westwards with a velocity of -50 km/h.
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.
Can a speed of a body be negative?
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
