Sim, é possível ter uma aceleração igual a zero enquanto a velocidade é diferente de zero. Vamos entender isso melhor:
Conceitos Básicos
-
**Velocidade:** É a medida da variação da posição de um objeto em relação ao tempo. Quando dizemos que um objeto tem velocidade diferente de zero, significa que ele está se movendo.
-
**Aceleração:** É a medida da variação da velocidade de um objeto em relação ao tempo. Se a aceleração é zero, isso significa que não há mudança na velocidade do objeto.
Situação
- **Movimento Retilíneo Uniforme (MRU):** Um exemplo típico onde a aceleração é zero e a velocidade é diferente de zero ocorre no movimento retilíneo uniforme. Isso acontece quando um objeto se move em linha reta com uma velocidade constante.
Exemplo Prático
Imagine um carro que está viajando em uma estrada reta a uma velocidade constante de 60 km/h. Se o carro não está acelerando (ou seja, não está aumentando ou diminuindo sua velocidade), então sua aceleração é igual a zero, mas sua velocidade continua sendo 60 km/h.
Conclusão
Portanto, sim, um objeto pode ter uma aceleração igual a zero e ainda assim ter uma velocidade diferente de zero. Isso ocorre quando o objeto se move com uma velocidade constante. Se precisar de mais explicações ou exemplos sobre esse tema, estou aqui para ajudar!
What else can I help you with?
Can you have a zero acceleration but non zero velocity explain it with help of a graph?
Yes, it is possible to have zero acceleration with a non-zero velocity. This occurs when the velocity is constant. On a velocity-time graph, a flat, horizontal line represents constant velocity, while a zero slope (flat line) represents zero acceleration.
Can you have a zero acceleration but non zero velocity.explain with graph.?
Yes, you can have a situation where an object has a non-zero velocity but zero acceleration. This occurs when the object is moving at a constant speed in a straight line. On a velocity-time graph, this would be represented by a horizontal line at a non-zero velocity value and a flat line at zero acceleration.
How an objects be motionless and in equilibrium?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
How can an object motionless and in equilibrium?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
What hasa zero velocity yet a non-zero acceleration?
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
An object experiencing a constant velocity has zero acceleration. This is because acceleration is defined as the rate of change of velocity over time. When velocity is constant, there is no change in velocity, leading to zero acceleration.
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.
Is it possible for a body to have zero velocity and non-zero acceleration?
Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non zero.
Can an object accelerate and have zero velocity?
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 55 mph is neither speeding up nor slowing down. Though it has velocity, there is no change in its velocity so acceleration will be zero. For a car parked on the side of the road, on the other hand, its velocity will be zero but what about its acceleration? Is velocity changing? No, so it will have zero velocity and zero acceleration.Yes.
Is it possible that there is a non-zero acceleration but with a speed of value zero?
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero 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?"
Is it possible for a body with zero velocity to have non-zero acceleration?
Yes, but only for a single instant in time. When you throw a golf ball or a rock straight up, it has the constant downward acceleration of gravity from the moment it leaves your hand, but its velocity is certainly not constant. The velocity steadily decreases until the peak of the toss, and then it switches from upward to downward velocity. At the very peak, the velocity is zero for an instant.
When an object and acceleration is zero at some instant t in time its velocity is?
If an object's acceleration is zero at a specific instant in time, its velocity can either be zero or a constant non-zero value at that instant. This means that the object could be either at rest or moving with a constant velocity at that particular moment.
