1. No, the speed of an object is not always constant. It can change due to various factors like acceleration, deceleration, or changes in direction, resulting in fluctuations in its velocity.

  2. Speed in the context of motion refers to the rate at which an object covers distance. It is a scalar quantity, indicating how fast an object moves without regard to direction.

  3. When velocity changes at a uniform rate, the average velocity is calculated as the arithmetic mean of the initial velocity (v₀) and the final velocity (v) over a specific period of time (t). Mathematically, it is represented as: Average velocity = 0 +v/2

  4. Velocity, unlike speed, incorporates direction alongside magnitude, indicating both how fast an object moves and in which direction. While speed measures the rate of motion without regard to direction, velocity accounts for both magnitude and direction, making it a vector quantity.
