Yes it can. Especially if it's riding the periphery of a roulette wheel, glued to the
rim of a car's tire, or spinning around your head on the end of a yo-yo string.
Velocity consists of speed and direction. If the direction of motion is changing
then the velocity is changing, even if the speed is constant.
What else can I help you with?
The difference in speed and velocity is that a measure of velocity must include?
Velocity differs from speed in that velocity includes the direction of movement in addition to the magnitude of speed. Therefore, velocity is a vector quantity that specifies both speed and direction, while speed is a scalar quantity that only represents the magnitude of motion.
What is a situation where instantaneous velocity is the same as average velocity?
A dog running in a circle, stopping where it started, would have a net displacement of zero, an average velocity of zero, and an average acceleration of zero regardless of the time involved. This is because the dog has exerted equal work in moving toward his starting point as moving away from that point. A similar situation exists where a book is lifted from a desk and then dropped back : the book has the same potential energy as before it was lifted, the additional energy having been removed by the force of gravity.
How will the velocity of the book change as it moves across a surface with no friction?
The velocity of the book will remain constant as it moves across a surface with no friction.
A book of mass m falls freely from rest to the floor from the top of a desk of height h. what is the speed of the book upon striking the floor?
The speed of the book upon striking the floor can be found using the equation for the final velocity of an object in free fall: v = sqrt(2gh), where g is the acceleration due to gravity.
Equal and opposite forces that do not produce an acceleration?
Equal and opposite forces that do not produce an acceleration are called balanced forces. When these forces act on an object, the net force is zero, causing the object to remain at rest or to move at a constant velocity without changing its speed or direction.
A science book is being pushed across a table Can the book have a constant speed and a changing velocity?
It can have a constant speed, and a changing velocity, but it cannot have the two at the same time. Remember: Velocity = speed with a directional component.
What includes velocity?

Is it possible for a book moving at a constant speed to have a change in velocity?
Yes, if an unbalanced force acts on the book, such as friction, which will slow the book down and eventually cause it to stop.
Is a book at rest on a table with gravity pulling down an example of acceleration?
Acceleration is zero in this case. Acceleration means the velocity is actually changing.

What does a venn diagram look like for velocity acceleration average speed speed inertia momentum?
Look it up on Google! This website is not an answer book. People are so lazy... So are you...it is called Answers.com right?!??!

How would the velocity of the book change if the applied force were equal to the sliding friction force?
If the applied force were equal to the sliding friction force, the book would move at a constant velocity since the two forces would be balanced. This means there would be no acceleration or deceleration, and the book's velocity would remain unchanged as long as the forces stayed in equilibrium.
Can a body have zero average velocity but a nonzero average speed give example?
The short answer is no it can't. There are a few more complex situations where you could argue the oposite: 1/ A race car doing laps around a circuit could have an average speed over 1 lap of 200mph but would have an average velocity of zero. This is because speed is a scalar measurement (how fast an object is moving) whilst velocity is a vector measurement (how fast an object is changing its position) Since the race car is at the start/finish line at the start and end of the lap it is in the same position so its average velocity is zero. Of course at any given moment during its lap its velocity would not be zero so I don't think this counts. Average velocity can be zero whilst average speed is not zero but "average" is the important word and isn't included in the question. 2/ Frames of reference - The Earth is travelling around the sun at a speed of roughly 67,000 mph (about 100,000 kph.) At what speed is a book sitting still on a table moving? If we use the Earth as a frame of reference then the book has a speed and velocity of zero. If we use the Sun as a frame of reference then the book is actually moving at a speed of about 67,000mph. (Plus or minus a bit for the rotation of the Earth about its axis.) If we use different frames of reference then a body can have zero velocity in one and non-zero speed in another. I'm inclined to think this is "cheating" and that the answer to the question remains no.
