Question

A car is moving with a constant velocity $30m{s^{ - 1}}$ . What is the speed of the car after $10s$ ?

Answer 1

An object must have a constant speed in a constant direction to have a constant velocity. The object's motion is restricted to a straight route when it has a constant direction. As a result, motion in a straight line at a constant speed is referred to as constant velocity.

Complete step by step answer:
One of the most basic types of motion is motion with constant velocity. This form of motion happens when an item moves (or slides) with little or no friction, and the object must move at a consistent speed and in the same direction. The object's motion is restricted to a straight route when it has a constant direction.
Now, coming to the given question;
"A car is moving with a constant velocity of $30{\text{ }}m{s^{ - 1}}$ .”
This means that the car's speed does not change over time, so the car is still going at $30{\text{ }}m{s^{ - 1}}$ after$10sec$ .

Additional Information:-
It is impossible to accelerate at a constant body speed. Constant speed refers to when an object's speed remains constant. The speed does not increase or decrease in this case.
If the centre of mass of a physical system has the same modulus as the velocity vector, it has constant speed. The slope might indicate whether the velocity is positive or negative.
Finally, the object is considered to have constant velocity when it travels the same distance every time. Then there's the complete absence of acceleration.
The body moves in a straight path and covers the same amount of ground in all directions.

Note: It's important to note that just because something is going at a constant speed doesn't mean it's not accelerating. It refers to the fact that it travels the same amount of distance in the same amount of time. The constant velocity denotes that the magnitude or direction of the velocity does not change.
