What else can I help you with?
Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
What is an example of constant speed with changing velocity?
Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.
Is motion with constant velocity an example of motion with constant acceleration?
Well, technically yes, and we even know the magnitude of the constant acceleration.If velocity is constant, that tells you that acceleration is zero, which sounds likea constant to us.
What is an Example of constant velocity?
constant velocity means the speed and direction are the same.
What is the difference of constant speed and changing velocity?
Constant means that something doesn't change; "changing" means that it does. Speed is a magnitude - measured (for example) in meters per second. Velocity, on the other hand, is a vector - which means that the direction is also considered. If an object changes direction - for example, moving in a circle - it is possible to do so at a constant speed. However, since the direction changes, the velocity will - by definition - change.
Does speed change with velocity?
If the velocity changes, the speed may, or may not, change. The velocity can be thought of as having two components: a speed, and a direction. It is possible to change only the direction, for example, when an object moves in a circle at a constant speed. In this case, the velocity changes, but the speed does not.
If a car moves at constant speed also moving at constant velocity give an example?
An example of a car moving at constant speed and constant velocity would be a car driving along a straight road with no change in direction, where the speedometer shows a steady reading, and there are no changes in velocity or direction of motion. This means the car is moving at a consistent speed in a straight line without any acceleration or deceleration.
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.
What is an example of an object moving at constant speed and constant velocity?
An object moving in a straight line at a speed of 50 km/h with a constant velocity of 50 km/h in the same direction is an example of constant speed and constant velocity.
How can an object accelerate if it is moving at a constant speed?
An object can accelerate even if it is moving at a constant speed if the direction of its velocity changes. Acceleration is defined as a change in velocity, which includes changes in speed, direction, or both. For example, a car moving in a circle at a constant speed is accelerating because its direction is constantly changing.
Does motion of seconds hand of a watch represent uniform velocity?
No, the motion of the seconds hand of a watch is not an example of uniform velocity. The seconds hand moves in a circular motion at a constant speed, rather than moving in a straight line at a constant velocity. Uniform velocity refers to motion in a straight line with a constant speed.
What is an example of concentric motion?
Example: Moon revolving around the sun (although it's technically elliptical not perfectly circular) -speed is constant but velocity changes constantly since the vector changes direction but not magnitude.
