Speed, instantaneous or not, is a term used for how fast an object travels.
Velocity, instantaneous or not, is a term used for how fast an object travels in a particular direction.
That's correct, the instantaneous magnitudes are equal. Non-instantaneous values may not be equal. For example, to find average speed, between two points, you divide the actual path distance by the time, but for average velocity you divide the straight line distance, between the points, by the time. The straight line distance could be quite a bit shorter then the actual path distance (for curved motion) so you could get a big difference between those averages. When calculating "instantaneous" values, however, the difference between "actual path distance" and "straight line distance" becomes insignificant, because you are using distances for infintesimally small time intervals.
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.
Speed has only size. Velocity has size and direction.If three drivers are driving their cars at 50 mph headed north, 50 mph headed south, and50 mph headed east, their speeds are all equal, but their velocites are all different.Instantaneous speed is the speed at an instant in time. A point on the edge of an LP record hasthe same instantaneous speed whenever you look at it.Instantaneous velocity is the velocity ... speed and direction ... at an instant in time. A point on theedge of an LP record has a different instantaneous velocity every time you look at it. Even thoughthe speed is always the same, the direction keeps changing.
Instantaneous speed can be thought of as the magnitude of instantaneous velocity. Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only indicates how fast an object is moving.
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.

It is the speed or velocity at a particular instant.
Instantaneous.

A car's speedometer typically shows the instantaneous speed, which represents the current speed of the vehicle at any given moment. It does not show average speed or velocity.
At a given moment in time, instantaneous speed can be thought of as the magnitude of the instantaneous velocity of an object. Instantaneous velocity is the rate of change of an object's position at that specific moment in time.
velocity
Instantaneous speed is the speed at a particular moment in time.The average speed of an object tells you the (average) rate at which it covers distance
average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)
