can an object have constant non zero velocity and changing acceleration?
18448
Acceleration is defined as the time derivative of the velocity; if the velocity is unchanging the acceleration is zero. Velocity is a vector, speed is a scalar magnitude of the vector. If the velocity vector changes direction you can have constant speed (not velocity) with a non-zero acceleration.

If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration. ... For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, then its constant acceleration is 3 m/s2.

Yes,a body can have zero velocity ,and constant acceleration. A body will have zero velocity when in a circular motion, i.e the body comes back to its initial position. ... Since the motion is circular,there will be a constant acceleration.

Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period. is the uniform rate of acceleration.

Explanation: If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that's not to say that there isn't work done by individual forces on the object, but the sum is 0 ).

Yes a body can definitely have acceleration if it is moving with constant speed. ... It's speed is constant but it has varying velocity as it changes it's direction, so there is always a acceleration acting towards centre which is provided by centripetal force.

Acceleration is defines as the change in velocity per unit time. If object is moving with uniform velocity, its velocity is constant, that means final and initial velocity are same.. so acceleration will be 0.

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.

If a body is moving with constant velocity, acceleration is zero. So net force acting on it will be also zero. But the body has energy due to its constant motion. Take the case of a freely falling body: it reaches its terminal velocity (120mph) when gravity = air resistance (drag).

Acceleration=Change in velocityChange in time. More precisely, the constant acceleration a is given by the formula. a=v(t2)−v(t1)t2−t1, where v(ti) is the velocity at time ti. Since velocity is a vector, so is acceleration.

If the motion is in a straight line with constant speed, then acceleration is zero. But if the motion is circular with a constant speed, then the acceleration is never zero. This is because at every point, direction of motion is changing, hence its velocity is changing, therefore, resulting in an accelerated motion.

Constant acceleration means the velocity vector changes. at a constant rate. You just studied 20 terms!

The object is either at rest and the velocity is zero, or it moves in a straight line with a constant speed. The acceleration of an object is parallel and directly proportional to the net force acting on the object, is in the direction of the net force and is inversely proportional to the mass of the object.

Acceleration is the change in velocity, not the velocity itself; therefore, an object can have zero velocity but not zero acceleration because the velocity will be changing.

It is possible for an object in free fall to have zero Acceleration. ... Acceleration is (the change in velocity) / (time interval). [The change in velocity divided by time interval] (True or False?)
