When a car turns and slows down while continuing to move in a straight line, its velocity undergoes several changes. Let's break it down:
Change in Direction: Turning the car causes a change in its direction of motion. Velocity is a vector quantity that includes both magnitude (speed) and direction. Therefore, when the car turns, its velocity changes because the direction component of velocity changes.
Decrease in Speed: Slowing down the car reduces its speed component of velocity. The car's velocity vector becomes smaller in magnitude as it decelerates.
Constant Forward Motion: Despite the change in direction and decrease in speed, the car continues to move in a straight line. This means that the car's velocity still has a component in the forward direction.
In summary, when a car turns and slows down while continuing to move straight, its velocity changes in terms of both direction and magnitude. The direction component of velocity changes due to the turn, while the speed component decreases as the car slows down.
