Is it possible for your speed to be zero when your acceleration is not zero?

Yes. Zero acceleration means you are not changing your speed (speed up or slow down) or changing direction. Zero acceleration is a constant speed in a linear direction. A speed implies you are moving.

Yes, it is possible for your speed to be zero even when your acceleration is not zero. This can occur at the peak of a projectile's trajectory, for example, where the acceleration due to gravity is acting downwards yet the object momentarily stops before changing direction.

When it activates its retrothrusters, its acceleration becomes negative (positive in the opposite direction). At the moment gravity and retrothrust cancel each other out, when the lander comes to a standstill, speed is zero. In the next moment the lander will have negative speed.

Can it be possible that a particle have constant speed must have zero acceleration?
Yes, it is possible for a particle to have constant speed and zero acceleration. If the particle is moving at a constant speed, it means that its velocity is not changing. Acceleration is the rate of change of velocity, so if the velocity is constant, the acceleration must be zero.
Is it possible that there is a non-zero acceleration but with a speed of value zero?
Yes, it is possible to have a non-zero acceleration while also having a speed of zero. This occurs when an object is changing direction but not its speed. For example, a car at a standstill that starts to accelerate in reverse has a non-zero acceleration but a speed of zero.
A car is moving with constant speed and yet the acceleration and net force are not equal to zero how is this possible?
This scenario is possible if the car is moving in a circular path at constant speed. In circular motion, even though the speed is constant, the direction of the velocity is constantly changing, which requires a centripetal acceleration towards the center of the circle. This acceleration is provided by a net force, known as the centripetal force, acting towards the center of the circular path.
When velocity is zero and acceleration is less than zero does the speed increase?
No, if velocity is zero and acceleration is less than zero, it means that the object is slowing down. Speed is the magnitude of velocity, so if acceleration is negative, the speed decreases.
What is the acceleration of an object that travels in a straight line at a constant speed?
The acceleration of an object moving in a straight line at a constant speed is zero. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity and thus no acceleration.
Can it be possible that a particle have constant speed must have zero acceleration?
Yes, it is possible for a particle to have constant speed and zero acceleration. If the particle is moving at a constant speed, it means that its velocity is not changing. Acceleration is the rate of change of velocity, so if the velocity is constant, the acceleration must be zero.
It it possible for an object to be sationary while under acceleration?
"Stationary" means zero speed. The object's speed is not changing, and the direction of the speed is obviously also not changing.By definition then, acceleration is zero.
Is it possible that there is a non-zero acceleration but with a speed of value zero?
Yes, it is possible to have a non-zero acceleration while also having a speed of zero. This occurs when an object is changing direction but not its speed. For example, a car at a standstill that starts to accelerate in reverse has a non-zero acceleration but a speed of zero.
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
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.
A car is moving with constant speed and yet the acceleration and net force are not equal to zero how is this possible?
This scenario is possible if the car is moving in a circular path at constant speed. In circular motion, even though the speed is constant, the direction of the velocity is constantly changing, which requires a centripetal acceleration towards the center of the circle. This acceleration is provided by a net force, known as the centripetal force, acting towards the center of the circular path.
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
When velocity is zero and acceleration is less than zero does the speed increase?
No, if velocity is zero and acceleration is less than zero, it means that the object is slowing down. Speed is the magnitude of velocity, so if acceleration is negative, the speed decreases.
Why is the velocity 0 when your speed is constant?
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.
How is it possible for a car to have an average velocity of zero and an average speed of 65 mph?
If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.
What is positive negative and zero acceleration is?
positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.
How is velocity of zero different from an acceleration of zero?
Velocity is the rate of change of an object's position over time. A velocity of zero means the object is not moving at all. Acceleration, on the other hand, is the rate of change of an object's velocity over time. An acceleration of zero means the object is moving at a constant velocity, not speeding up or slowing down.
