Why achanging velocity cannot maintaining constant speed?
A changing velocity can maintain constant speed if the motion is circular. The constant change in direction is a change in velocity, even if the speed is constant.
What is an example of constant speed with a change in velocity?
rotational motion
Can a body move with a constant velocity in an accelerated motion?
No. The definition of acceleration is change in velocity.
Why is an object traveling in a circular motion?
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
What is constant accelertion?
It is a characteristic of the motion of a body in which the rate of change of velocity - with respect to time - has a constant value.
Is the velocity constant for an object in uniform circular and why?
The velocity of an object in uniform circular motion is constant, because, velocity is the rate of change of position at a given time or speed.
What are the condition of an object to stay at rest to keep moving with constant velocity or to move with incresing velocity?
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction.
