Does constant acceleration mean zero acceleration?
Constant acceleration means that the acceleration does not change. Some would say that if the acceleration is zero then the acceleration does not change and so one can say that the acceleration is constant.
What is the acceleration when the velocity is zero?
At the highest point, the velocity of the ball becomes zero, after which it starts to fall down. At this point, the velocity of the ball is zero yet its acceleration is equal to g=9.8m/s2. This property can also be observed in a Simple harmonic motion of a spring or a pendulum.
Is zero velocity considered constant velocity?
The constant velocity means that and so automatically satisfy this relation. So, we can say the zero velocity is constant velocity.
Does 0 velocity mean 0 acceleration?
If the velocity is constant however, the acceleration is zero (because the velocity isn’t changing over time). Although at an instant in time it is possible to have zero velocity whilst accelerating. For example, if you drop an object at the instant you release it it has zero velocity but it is accelerating.
Can velocity be zero but not acceleration?
Yes, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction. Now, suddenly a force acts on it and tries to accelerate the object in the reversed direction.
Is constant velocity equal to constant acceleration?
The rate of change of the velocity of a particle with respect to time is called its acceleration. If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration.
What happens when velocity is zero?
While velocity is a measure of speed in a vector, acceleration measures the change of speed (also in a vector). If velocity is 0 , that means the object is not moving, but with acceleration present, there is a force acting on the object.
Can a body have zero velocity and non zero acceleration explain with an example?
A body may have zero velocity but non-zero acceleration. For example, when a body is thrown vertically upwards at the maximum height the body momentarily comes to rest. At this point the body attains zero ation due to gravity directed downward.
Can an object have acceleration but constant velocity?
An object cannot have acceleration but constant velocity. Acceleration is defined as change in velocity. So, either the magnitude or the direction of velocity has to change for acceleration to exist.
Can velocity be negative when acceleration is zero?
Since the final position of the object (rfinal) may be either positive, negative, or zero, and either larger, smaller, or the same as the initial position (rinitial), the velocity may be positive, negative, or zero.
Can a body have zero velocity but still be accelerating give a suitable example?
Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up. At the peak point its velocity becomes 0 but still accelerates due to gravity.
Can a body have constant velocity but non-zero acceleration?
As per definition, acceleration is the rate of change of velocity, i.e., →a=d→vdt. If velocity is constant d→vdt=0∴→a=0. Therefore, if a body has constant velocity it cannot have non-zero acceleration.
