If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
In which type of motion is the average velocity of an object equal to its instantaneous velocity?
The average velocity of an object is equal to its instantaneous velocity in uniform motion. Uniform motion occurs when an object moves at a constant speed in a straight line, resulting in a constant velocity throughout the motion.
Does the instantaneous speed ever equal the magnitude of its average velocity?
Yes, instantaneous speed can be equal to the magnitude of the average velocity when an object is moving in a straight line without changing its direction during the motion. This occurs at the moment when the instantaneous velocity vector is in the same direction as the average velocity vector.
Define speed at which an object is moving at a given instant time?
Instantaneous speed is the rate at which an object is moving at a specific moment in time, indicated by the object's speedometer reading or GPS device. It provides the actual speed of an object at that instant, accounting for any changes in velocity.
How is velocity same from instantaneous speed?
Velocity is a vector quantity that includes both speed and direction, while instantaneous speed is the magnitude of velocity at a specific moment in time without considering direction. In other words, velocity accounts for the object's motion in a specific direction, whereas instantaneous speed is the rate at which an object is moving at a given instant, regardless of direction.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
Can the average speed ever equal the instantaneous speed?
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
Is instantaneous speed final speed?
No instantaneous speed is not final speed.

What instantaneous speed does not change an object is moving a?
If an object's instantaneous speed is constant, then the object is moving at a constant speed without accelerating or decelerating. This means that the object is traveling at a steady rate without any changes in its velocity.
What is random motion with examples?
Motion whose direction and speed changes continuously is called random motion. Eg:a fish swimming in water , a flying butterfly ,a bird flying in the sky,etc.
Does the speedometer of a car read average speed or instantaneous speed?
instantaneous speed
The resistance of an object to changes in its motion?
The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
An objects speed at a particular moment in time is called?
Instantaneous Speed.
