Is it possible for any moving object that speed is constant but velocity is changing ?

Velocity can change without change in speed.

Is it possible for any moving object that velocity is constant but speed is changing ?

Assertion:- For a particle moving along a straight line, if they velocity and acceleration have same sign, then the particle may be slowing down. Reason:- For a moving particle speeding up and slowing down does not depend upon the angle between velocity and acceleration.

A particle is moing with a velocity of 10m//s towards east. After 10s its velocity changes to 10m//s towards north. Its average acceleration is:-

Assertion :- A particle having zero acceleration must have constant speed. Reason :- A Particle having constant speed must have zero acceleration.

An ant is moving on the surface of a ball. Does it’s velocity change or not? Explain.

What is the deceleration of a vehicle moving in a straight line that changes its velocity from 100 km/h to a dead stop in 10s?

What will be change in speed of moving object if both speed and acceleration are positive or negative?

Assertion: In projectile motion, the acceleration is constant in both magnitude and direction but the velocity changes in both magnitude and direction. Reason: When a force or accelration is acting in an oblique direction to the direction of velocity then both magnitude and direction of the velocity may be changed.
