If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
. . . constant speed, although its velocity may easily be changing.
constant speed
B. The direction of the object's velocity is constant.
When an object travels covers equal distances in equal amount of time it can be said that it is traveling with constant speed. speed = distance/time. Unit of speed is m/sec. speed is a scalar quantity.
Momentum is mass times velocity, if the velocity of the two are the same, the object with the greater mass will have proportionally greater momentum.
The speed of an object at any instant in time is its instantaneous speed.
When a moving object is pushed in the direction of its motion the speed of the object increases
When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
a car traveling the speed limit
No, speed is directionless.
Speed and velocity have both changed.
subsonic
there's four speed. There are constant speed, average speed, increasing speed, and decreasing speed. choose one of them
It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.
Electrons are able to travel close to speed of light.
constant speed
Both the speed and velocity have increased as a result of acceleration.
uniform
That's the object's 'speed'.
