WebAug 27, 2024 · Q.6. Assertion : An object may have acceleration even if it is moving with uniform speed. Reason : An object may be moving with uniform speed but it may be changing its direction of motion. Answer Answer: (a) Both assertion and reason are true and reason is the correct explanation of assertion. The uniform motion only means that … WebHere, the speed is constant but the velocity changes. If a particle is moving in a circle, it must have some acceleration acting towards the center which is making it move around the center. Since this acceleration is perpendicular to the velocity of a particle at every instant, it is only changing the direction of velocity and not the magnitude. WebVelocity is a vector quantity, and the velocity of an object is its speed in a given direction; When an object travels along a circular path, its velocity is always changing. The speed of the object moving in a circle might be constant - that is, it is travelling the same distance every second; However, the direction of travel is always changing as the object moves … cape liberty 2024 sailings
