Is it possible to round a curve with zero acceleration

Is it possible for speed to be constant while acceleration is not zero? Give an example of usch a situation. No, It is not possible. A car moving at a constant speed changing direction.

Is it possible to round a curve with zero acceleration? With constant acceleration? If either the speed or the direction or both is changing, then the velocity is changing. Constant speed and constant velocity are not the same. A body may move at constant speed along a curved path but it does not move with constant velocity, because its direction is changing every instant. For example, the car could be traveling at constant speed around a corner.

If you have a constant velocity, this means you have zero acceleration. There are two important types of constant motion: constant speed and constant acceleration. Not with any sensible definition of "acceleration" and "velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?

Yes friend : actually the definition of velocity is the time rate change in acceleration but if we throw some thing upward then a point comes where velocity of the body is Zero but acceleration due to gravity is present. Acceleration is the change of velocity. If velocity is constant, at any speed, acceleration is zero. The object's speed is not changing, and the direction of the speed is obviously also not changing. By definition then, acceleration is zero. It won't have zero velocity for long, but it's possible for the instantaneous velocity to be zero when the acceleration is non-zero.

For example, if you throw a ball straight up, at the very top of its path it's not moving upward or downward, but it still has an acceleration, and will fall from that point starting immediately. The definition of acceleration is a change in velocity, i. So constant velocity means zero acceleration. 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. Zero acceleration means no change in velocity and no force on the zero accelerating body. It's possible. A ball or a stone tosssed straight up has a constant acceleration of 9. It's possible for an object to have velocity equals to zero at some moment and to have some acceleration when you throw a baseball upwards with the gravitation present, the ball reaches its maximum point and then starts to come back at its maximum height its velocity is zero while acceleration equals g.

When an objects net force is zero, its acceleration is zero. No force , no acceleration. Log in. Study now. See Answer. Best Answer. Study guides.
