Question

A train moving at uniform speed along a curved track is said to have a variable velocity. Explain.

Answer 1

Explanation:

as velocity is a vector quantity, it must also have a direction. when an object is traveling in a circle, it's direction changes at every point, so velocity also changes at every point

plz mark brainliest as it is larger and better

Answer 2

Answer: Velocity is a vector quantity so it has variable velocity on a curved track.

Velocity: Velocity is the speed of an object in a particular direction. Since it has both magnitude and direction so it is a vector quantity.

Explanation:

• It is given that the train is moving at a uniform speed.
• But it is moving in a curved track due to which it will change its direction
• Since Velocity to be uniform, The speed and direction both of the train are required to be not changing
• Therefore it is said that trains moving at uniform speed along the curved track will have variable velocity.
