Is it necessary for acceleration to be zero when velocity is zero?

Is it necessary for acceleration to be zero when velocity is zero?

Here, accelerations deals with the rate of change in velocity, which means you need the change in velocity . In case, if the question means that if the velocity is always 0 then, the acceleration is always zero. But if the final velocity is zero then the acceleration is negative i.e deceleration.

What happens to acceleration at maximum velocity?

Terminal velocity is achieved, therefore, when the speed of a moving object is no longer increasing or decreasing; the object’s acceleration (or deceleration) is zero. …

Can velocity be zero but not acceleration?

It is possible to have a non-zero value of acceleration when the velocity of a body 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.

What happens maximum velocity?

Maximum velocity is top-end speed. It’s that moment when you can no longer accelerate. At maximum velocity, these positive and negative forces equal out. You can’t get any faster.

Is velocity 0 at the highest point?

At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero.

Why is acceleration not zero at maximum height?

At maximum height the final velocity becomes zero but NOT the acceleration or gravitational fields strength (g) because it is the intrinsic property of the mass so the value of g at that height is 9.8 m/sq.

Can maximum velocity negative?

If acceleration is negative to the left and positive to the right, the point is a minimum velocity. If acceleration is positive to the left and negative to the right, the point is a maximum velocity.

Why is acceleration zero at the point of maximum velocity?

It is not that velocity is maximum, that’s why the acceleration is zero. The velocity is maximum there because acceleration changes direction at that point, hence at all other points, the accel Acceleration is zero because at that point, it is the mean position, which means it is the equilibrium position.

What does it mean when the velocity of a body is maximum?

The velocity of a body is maximum means that you can not increase it further. Means change in velocity is zero. Means change in velocity is zero. Hence acceleration is zero.

What is the difference between acceleration and max acceleration?

Acceleration is change of velocity per unit time i.e. if you are accelerating your velocity is changing. But if you are at max. velocity that means the velocity cannot go higher, so acceleration needs to be 0.

Why is acceleration non zero at the end of a pendulum?

Hence, the spring is not compressed (or extended) or the pendulum suffers no tangential force. However, at that point, due to velocity being non-zero, the object crosses the mean position (law of intertia), and the acceleration again becomes non zero!
