Explain whether a car can move with changing velocity while maintaining constant speed?

Velocity is a quantity that has magnitude and direction. The magnitude of velocity is what we call "speed".
If the velocity is constant, then its magnitude and direction are both constant.
Constant magnitude means constant speed.
So the answer to the question is "Yes".

Velocity does change during circular motion, because at one point in the circle you might be moving in the x direction, and later on in de -x direction.
Speed is the absolute length of velocity and that remains constant.

∙ 14y ago- The acceleration of the car is zero
- The Kinetic energy of the car is constant
Wiki User
∙ 14y agoNo. The car is not accelerating if at constant velocity. Acceleration is the change in velocity with time.
Wiki User
∙ 11y agoIf the momentum doesn't change, the velocity doesn't change, either, since we can assume that the mass will hardly change.

Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
Explain why you don't do any work when you carry an object at a constant velocity?
because it stays the same
Explain why velocity changes while driving around a circular track even if the speed is constant?
Velocity consists of a speed and a direction. If any of the two changes, the velocity changes.
How do you explain streamline flow?
a fluid in which ita velocity at any point is constant or varies in a regular manner.
Does a change in direction affect velocity explain?
Direction does not have to change when velocity is changed. You can move North at 10 m/s and change it to 8 m/s a second later. You would still be moving North. But since velocity is a vector, if direction changes, even though speed (magnitude of velocity) remains constant, then velocity most certainly changed, since both magnitude and direction make up the vector.
Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
Can an object have a constant speed and the varying velocity at the same time explain?
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
Explain how distance time and velocity are related to each other?
They are related through the formula distance = time x velocity (assuming constant velocity).
Explain why you don't do any work when you carry an object at a constant velocity?
because it stays the same
Explain why velocity changes while driving around a circular track even if the speed is constant?
Velocity consists of a speed and a direction. If any of the two changes, the velocity changes.
Can your body sense constant velocity and explain?
Your body cannot sense constant velocity. For example, you cannot sense that the earth is turning nor can you sense that the earth is orbiting around the sun. And, if you are in a vehicle that is traveling with a constant velocity, you cannot sense that you are moving unless your eyes sense a change in position.

a fluid in which ita velocity at any point is constant or varies in a regular manner.
An ice skater glides around a rink at a constant speed of 2 ms is the skater acceleratng explain your answer?
Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.
Does a change in direction affect velocity explain?
Direction does not have to change when velocity is changed. You can move North at 10 m/s and change it to 8 m/s a second later. You would still be moving North. But since velocity is a vector, if direction changes, even though speed (magnitude of velocity) remains constant, then velocity most certainly changed, since both magnitude and direction make up the vector.
Explain what homeostasis means in a physiological sense?
Homeostasis means maintaining a stable internal environment, despite changing external conditions.
If the speedometer of your car reads a constant speed of 40km per hour can you say 100 for sure that the car has a velocity explain your answer?
Ok but did I ask?
Can an object be accelerated if it is moving with constant speed If yes explain giving examples.?
Yes, it can. Perhaps the simplest example is when an object moves at constant speed, in a circle. In this case, the speed doesn't change; the velocity does.
