# Can velocity be zero and acceleration not?

Yes. If you throw an object up, the moment it is at its highest
point, the velocity **at that instant** will be zero, whereas
the acceleration is -9.8 meters per second square. In other words,
the velocity won't remain zero for a long time.

### If an object has zero acceleration and does that mean its velocity is zero and Explain?

If an object has zero acceleration, its velocity doesn't have to be zero. Acceleration is a measure of the change in velocity over time. Zero acceleration means there is no change in velocity over time, namely constant velocity. Constant velocity can be any velocity (including zero velocity or "at rest"), so the object's velocity doesn't have to be zero to have zero acceleration.

### Can an object have zero velocity and zero acceleration?

I'm not a scientist, but the following seems reasonable to me. If your frame of reference is the earth's surface, then it seems clear that an object can have zero velocity and zero acceleration. You could even have non-zero velocity and zero acceleration. What seems impossible is to have zero velocity and non-zero acceleration. When you think of accelaration think of changing velocity. A car moving straight down the highway at a constant speed of…

### If velocity is zero acceleration is zero?

Yes...acceleration is the rate of change of velocity with time.....therefore when velocity is zero..definitely acceleration is zero This is not exactly true; at an instant in time the acceleration can be non-zero while the velocity is zero. However, this would change the velocity to non-zero after any amount of time. An example of this is when you throw a ball into the air: at it's highest point, the velocity is zero (it changes from going…

### What is the acceleration of a ball that is traveling at a constant velocity of 50 meters per second and has been traveling for 2 minutes?

zero - it is constat velocity. so acceleration is zero 50 m/s2 Another : The acceleration is ZERO. Acceleration is defined as the change in velocity per unit time. If the ball is traveling a constant velocity over a two minute period, the acceleration would be zero since there is no change in velocity.

### Can a body resting on a table have zero velocity and nonzero acceleration?

It depends on the frame of reference (where it is).On Earth a body on a table is still rotating around the centre of the Earth. This implies a change of direction and thus having a velocity around the centre and an acceleration acceleration due to centripetal force that makes a body follow a curved path. Eben without this the body is orbiting the sun with the same impact
