What else can I help you with?
Can a car move with changing velocity while maintaining constant speed?
No, if a car is changing velocity, it is not maintaining a constant speed. Velocity includes both the speed and direction of an object's motion, so any change in velocity would involve a change in speed, direction, or both.
Is it true or false that a body traveling at constant speed changes its direction without a change in its velocity?
False. A body traveling at constant speed does not change its velocity, which includes both speed and direction. Therefore, in order to change direction, the body would need to change its velocity, which also involves changing its speed.
How would the velocity of an object change when the speed stays the same?
Velocity is a vector quantity that includes both speed and direction. If an object's speed stays the same but its direction changes, its velocity will change. This is because velocity takes into account the speed of an object as well as its direction of motion.
What is the magnitude of average velocity?
The magnitude of average velocity is the total distance traveled divided by the total time taken, regardless of the direction. It gives the overall speed at which an object has moved over a certain period.
If the velocity is constant does that mean that there is no change in momentum?
No, a constant velocity means that there is no change in speed but there can still be a change in direction, which would lead to a change in momentum since momentum is a vector quantity that considers both speed and direction.
What would have to be true for the velocity to be constant?
the speed would have to change.

Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
What is speed in calculus?
Speed is an example of a rate of change. It is specifically the rate of change of distance over time.In calculus, speed is the absolute value of velocity. Velocity measures both speed and direction, while speed only measures speed. For example, if a car is driving backward with a speed of 90km/h, its velocity would be -90km/h because "backward" indicates a "negative" velocity.
When can an object a constant speed but not a constant velocity?
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.
If the velocity is constant does that mean that there is no change in momentum?
No, a constant velocity means that there is no change in speed but there can still be a change in direction, which would lead to a change in momentum since momentum is a vector quantity that considers both speed and direction.
How would you describe the values for acceleration?
positive or negative change of velocity or change of direction of the speed vector
What does a flat line on a velocity -time graph represent?
A flat line would indicate a constant velocity, no change in speed.
What is an example of the word velocity?
Velocity means speed or speediness. When you drive a car at 55 mph, that would be it's velocity. It does have an upper limit of velocity. It can also mean the rate of change in speed. You can also look at it as the speed that gets you get up to 55 mph.
