How is velocity of zero different from an accerlation at zero?
Velocity at zero means the object is not moving, while acceleration at zero means the object is moving at a constant velocity. Velocity at zero can be motionless or stationary, while acceleration at zero indicates that there is no change in velocity, even if the object is moving.
Zero velocity is also called?
Zero velocity is also called stationary or at rest.
Can stationary have non zero angular acceleration?
No, an object is considered stationary when it has zero velocity and zero acceleration. Angular acceleration refers to the rate at which an object's angular velocity changes over time. If something has a non-zero angular acceleration, it means that it is rotating at a changing rate.
Does a stationary object have momentum?
No, a stationary object does not have momentum because momentum is the product of an object's mass and its velocity. If an object is not moving (velocity is zero), then its momentum will also be zero.
Why can velocity be zero?
Velocity can be zero if an object is at rest or not moving. This means that the object's speed and direction are not changing over time. In other words, the velocity of an object is zero when there is no movement or change in its position.
What is the movement of a stationary object in physics?
In physics, a stationary object has zero velocity and does not change its position with time. This means that there is no movement or change in location of the object relative to its surroundings.
What is an object that's not moving?
A stationary object with velocity of zero.
If object is stationary is its accelaration necessarily zero?
Yes, if an object is stationary, its acceleration is zero because acceleration is the rate of change of velocity over time. When an object is not moving, its velocity is constant and therefore there is no change in velocity, resulting in zero acceleration.
What is the acceleration of vehicle moving with uniform velocity?
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.
Does a stationary object has interia and momentum?
Yes, a stationary object still possesses inertia, which is its resistance to changes in motion. However, since momentum is dependent on an object's mass and velocity, a stationary object has zero momentum.
Why the velocity of fluid is zero at stationary boundary?
The velocity at a stationary boundary is zero because the boundary is not moving, thus preventing the fluid from moving past it. This creates a no-slip condition where the fluid particles in direct contact with the boundary stick to it and do not move. This stagnant layer of fluid at the boundary sets the velocity at zero.
Can you tell from a velocity-time graph whether an object is stationary?
If the curve is horizontal, then the speed is constant. If that horizontal graph lies on the x-axis, then the constant speed is zero, and the object is stationary.
