Why is an object traveling at a constant speed but turning left said to be accelerating?
Acceleration is not a change in speed, but a change in velocity. Velocity is, unlike speed, a vector, and so as the direction of velocity changes there must be an acceleration to cause that change.
Can the velocity of a car which is turning a curve be held 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 ... :) :]
When cars are changing direction they are also changing what?
When cars are changing direction, they are also changing their velocity vector, which includes speed and direction. This change in velocity requires acceleration, which can be in the form of turning left or right, slowing down, or speeding up.
If a car turns right can acceleration be zero?
No, any turning object undergoes acceleration because the direction is always changing. The acceleration vector points into the circle of rotation, and the velocity vector is a tangent line to the circle at any given point. The equation is Centripetal Acceleration=v^2/r
Can a body have acceleration with zero velocity?
Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
What is the angular velocity in radians per second of a pulley turning at 1800 RPM?
The angular velocity of a pulley turning 1800 rpm is 60 pi radians per second.

Can velocity of an object be zero at the same instant its acceleration is not zero?
Yes. For example a swinging pendulum has zero velocity at the turning point but acceleration is not zero.

What is the function of universal joint in vehicle?
To enable constant velocity. It keeps a shaft turning through a range of angles.
How do you adjust paintball marker?
You can adjust the marker by turning the velocity screw. It is in a different place for every gun. This changes the FPS.
What does it mean when a 04 Nissan sentra makes a popping noise in reverse while turning?
could be a contant velocity joint

What occurs any time an object speeds up or slows down or changes direction?
Acceleration. Acceleration is change in velocity. Velocity is its speed and direction. So when one of these things changes, it is undergoing acceleration. Acceleration can be the object speeding up, slowing down, turning right, turning left, etc. Deceleration is lowering the rate of change. You are experiencing no change if you are moving in a straight line at a constant speed.
Can a body have acceleration with zero velocity?
Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
At what points does velocity change direction?
The velocity of an object can only change if it is accelerating and if this is constant and continuous. Velocity will also only change direction if acceleration is greater than zero and will not work if at zero.
