Question

When a car runs on a circular track with a uniform speed, its velocity is said to be changing. This is because ______.

Options

• the car has a uniform acceleration

• the direction of car varies continuously

• the car travels unequal time intervals.

• the car travels equal distances in unequal time intervals

Answer 1

When a car runs on a circular track with a uniform speed, its velocity is said to be changing. This is because the direction of car varies continuously.

Explanation:

Velocity is a vector quantity, which means it has both magnitude (speed) and direction. Even if the car is running on a circular track at a uniform speed, its direction changes continuously as it moves along the curve. This change in direction results in a change in velocity, even though the speed remains constant.
