What is instantaneous velocity?

Is it true that the instantaneous velocity of a projectile is tangential to its parabolic path ?

The average velocity of a particle moving on a straight line is zero in a time interval. Assertion :- It is possible that the instantaneous acceleration is never zero in the interval. Reason :- It is possible that the instantaneous velocity is never zero in the interval.

When a particle moves with constant velocity its average velocity, its instantaneous velocity and its speed all are equal. Is this statement true or false ?

A bus moves with uniform velocity along a straigth line path. If the average velocity of the bsu is 80 km h^(-1) , then its instantaneous velocity at t=0 is ________

A man moves in x-y plane along the path shown. At what points is his average velocity vector in the sam direction as his instantaneous velocity vector. The man starts from point P .

When a particle moves with constant velocity, its average velocity, its instantaneous velocityi and its speed are all equal. Comment on this statement.

A particle is moving with a constant speed in a circular path. Find the ratio of average velocity to its instantaneous velocity when the particle rotates an angle theta =((pi)/(2)) .

Velocity-time graph cannot be used to find instantaneous velocity

What is the difference between average velocity and instantaneous velocity?
