Can a body moves with a constant velocity in an accelerated motion?

Can a body moves with a constant velocity in an accelerated motion?

Complete answer: If a body has constant velocity, it means that the magnitude of the velocity and the direction of the velocity vector will remain constant. Again, since the acceleration is the rate of change of velocity of a body with time, if the velocity is constant, the acceleration of the body will be zero.

Can a body travels with uniform velocity and still be in accelerated motion?

(i) A body can have acceleration even when it has uniform speed. A body in uniform circular motion has uniform speed but at every point its direction of velocity changes, so its motion is accelerated. (ii) Yes, a body can have acceleration even when its velocity is zero.

Can a body move with constant acceleration but with zero velocity?

One example of this is the vertical motion of an object. When the object is thrown upwards and reaches the maximum height, the velocity of the body becomes zero, but it still accelerates with constant acceleration. Hence, we can say that an object moves with acceleration and constant speed in a uniform circular motion.

Can a body have 0 velocity and still be accelerating?

Yes, an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction.

What does it mean a body is moving with positive velocity with zero acceleration?

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

Does constant acceleration mean zero velocity?

Since acceleration is the change in velocity over time, there has to be a change in velocity for something to accelerate. In other words, if something is accelerating, it has to have a variable velocity. If the velocity is constant however, the acceleration is zero (because the velocity isn’t changing over time).

Is it possible for a body to have zero velocity but non-zero acceleration?

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 a body have acceleration without velocity give example?

If the body moves with constant speed without changing the direction, the acceleration of the body is zero. ie, for constant velocity and no change in direction = no acceleration. Yes , the body have acceleration with zero velocity.

Can a body have positive velocity and negative acceleration?

Explanation: Yes, a body can have positive velocity and negative acceleration at the same time. For example when a lift goes upwards from 4th to 8th floor considering base as origin and get stopped , then velocity is positive while acceleration is negative.

What is the implication to a body when its acceleration is zero?

When acceleration is zero (that is, a = dv/dt = 0), rate of change of velocity is zero. That is, acceleration is zero when the velocity of the object is constant. Motion graphs represent the variations in distance, velocity and acceleration with time.

What happens to velocity if acceleration is constant?

If we say that an object has some acceleration than that means the velocity of the object is changing with time. A constant acceleration would mean the velocity will change at a constant rate with time.

Does velocity increase with constant acceleration?

Sometimes an accelerating object will change its velocity by the same amount each second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity.

Why is the motion of a body moving with a constant speed around?

Why is the motion of a body moving with a constant speed around a circular path said to be accelerated? Since in an uniform circular motion, although the speed of body remains constant but the direction of velocity of the body changes continuously and hence the velocity of the body changes at every instant.

Why is the acceleration of the body constant?

Acceleration of the body is defined as the rate of change in velocity of the body. Hence the body is said to be accelerated though the speed is constant in a circular path. Was this answer helpful?

When does an object move with constant acceleration?

Motion with constant acceleration. Motion with constant acceleration occurs in everyday life whenever an object is dropped: the object moves downward with the constant acceleration , under the influence of gravity. Fig. 8 shows the graphs of displacement versus time and velocity versus time for a body moving with constant acceleration.

What makes a circular motion an accelerated motion?

A body moving in a circular path with constant speed is an accelerated motion. Why? Acceleration is a rate of change of velocity with respect to time. In the circular motion, the speed of the body is constant but velocity changes continuously as it’s direction changes.
