No it cannot. It is either one or the other.
For constant velocity, acceleration must be 0, meaning there is no acceleration happening here.
If there is constant acceleration, then the velocity is constantly changing.
No. A object can have acceleration while moving at a constant speed (like the earth in its orbit around the sun). But once you use the word "velocity", you've expanded the decription of its motion to include the direction as well as the speed. The definition of acceleration is a change in either speed or direction, so if there is acceleration, then either the speed or the direction of the velocity (or both) is changing, so the velocity is not constant.
No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.
Yes, the direction of an object's velocity can reverse even when it is experiencing constant acceleration. This can happen if the acceleration is in the opposite direction to the object's initial velocity.
Unless the object is changing its direction, it is not accelerating. Constant velocity implies that speed and direction are constant, and for acceleration to occur, either speed, direction, or both values must be changing.
No, if an object's speed is constant, then it is not accelerating. Acceleration is the rate of change of an object's velocity, which includes both speed and direction. If an object's speed is constant, it means there is no change in velocity and therefore no acceleration.
An object with a constant acceleration and velocity in the same direction will have both vectors pointing in the same direction. This occurs when an object is moving in a straight line with a constant speed while its velocity is also increasing at a constant rate.
Acceleration = Change in velocity divided by the change in time. This formula only works if velocity is constant. If velocity is not constant, find the acceleration for both points in time. Then add the two accelerations and divide by 2.
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
The velocity and acceleration of a body are parallel when the body is moving along a straight path with a constant speed. In this case, the velocity is constant, and since acceleration is the rate of change of velocity, it is zero. Therefore, both the velocity and acceleration vectors are parallel and pointing in the same direction.
a=dv/dt. By definition, acceleration is the rate of change of velocity. In mathematical notation, it is given as the formula stated above. Two special cases: 1. When acceleration is constant: The rate of change is a constant. Therefore, it can be calculated by: a=(vf - vi) / t where a is acceleration vf is final velocity vi is initial velocity and t is time taken 2. When velocity is constant: Velocity is not changing. The rate of change of velocity is zero. Acceleration has to be zero. * * * * * Note that velocity and acceleration are both VECTORS. Therefore, an object going round in a circle, at CONSTANT speed, has velocity and acceleration that are changing all the time - because the direction of motion is changing.
Both uniform linear acceleration and acceleration due to gravity involve constant acceleration which causes an increase in velocity over time. They both follow the laws of motion described by Newton's second law, where acceleration is proportional to the force applied. In both cases, the rate of change in velocity is constant.
An object moving in a circle at a constant speed undergoes acceleration because its direction of motion is continuously changing, even though its speed stays constant. This acceleration is called centripetal acceleration and is directed towards the center of the circle.
