The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.

Yes, the velocity is changing. Velocity is a quantity composed of the speed and the direction of motion. Constant velocity means: Constant speed, in a straight line. If the direction is changing, then the velocity is changing, even if the speed is constant.


Acceleration does not mean speeding up. It means any change in the speed or direction of the motion. A particle moving around a curve is constantly changing the direction of its motion, and that's called acceleration, regardless of whether or not the speed is changing.


If the speed is constant, the acceleration is toward the center of the circle.



utility is not constant along the demand curve


Constant speed around a curve is changing velocity.


Yes. The simplest example is an object moving at a constant speed in a circle.


The speed of the object in motion, the radius of the curve in which it moves, the force acting on it to keep it moving in a circle, its angular velocity, and its centripetal acceleration, are all constant. Notice that its linear velocity is not constant, because the direction of its motion is always changing. Although I guess you'd have to say that its velocity is constant in polar coordinates, because the radial and tangential components are constant.


This may have been the result of steering the car around a curve in the road while maintaining constant speed.


No. It can keep a constant SPEED in a curve. But if the direction changes, then that's a change of velocity, and the direction in a curve is constantly changing.


Of course, since velocity is a vector quantity and speed is a scalar quantity, velocity has something speed does not: direction. Thus, an object can travel at the same speed by has a changing direction of movement, and therefore a changing velocity. For instance, a ball on a string moving in a circle at the same speed is constantly changing its velocity, which results in its path of motion.Yes. Velocity is (speed and direction of motion). If direction changes, then velocitychanges, even if speed is constant.Examples:-- Car going around a curve at a constant speed has changing velocity.-- Anything traveling a circular path at a constant speed has changing velocity.



No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.


The nature of uniform motion for a velocity-time graph is graphed as a horizontal straight line. Uniform motion is unaffected by acceleration (line does not curve), which means that it goes up or down in a constant rate on a position-time graph. Velocity= the slope of a position-time graph. So, if the motion is constant on a position-time graph then the velocity of the uniform motion is constant on a velocity-time graph. Lauren "Physics above all!"


Yes an object can be accelerate if its moving along a curve path because when the object moves along a curve path it has constant speed and there is still change in velocity and change in velocity has acceleration


Yes, it is accelerating into a different velocity (i.e. direction)


if the slope of offer curves is constant, the terms of trad will


growth & constant stable


Velocity magnitude is unchanging at constant speed. The direction might change (velocity is a vector with both size (speed) and direction) if , for example, you are driving around a curve at a constant speed.


Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.


-- changing direction of motion, like around a curve or a corner -- slowing down -- speeding up


prices will fall if demand decreases and the supply is constant. the supply curve will be vertical and demand curve will be downward sloping.


Yes. Velocity combines the descriptions of speed and direction. If the direction of motion is changing, like moving along a curve or bouncing off a wall, then the velocity is changing, even though the speed may be constant.


The speed can be constant but the velocity can't, because the directionof motion ... which is a component of velocity ... is changing. Also the velocity of a moving body changes when its speed changes but remains moving towards the same direction ... :) :]


Velocity is the measurement consisting of speed and direction. When you move along a curve, your speed may be constant, but your direction is constantly changing, so any measurement that includes information about the direction of your motion is also constantly changing.
