What are some examples of uniform velocity and how is it defined in physics?
Uniform velocity is when an object moves in a straight line at a constant speed. Examples include a car driving on a highway without changing its speed, or a ball rolling down a ramp at a steady pace. In physics, uniform velocity is defined as the rate of change of an object's position over time, where the object covers equal distances in equal intervals of time.
How can you change only one component of the velocity without changing the speed?
You can change the direction of the velocity without changing the speed. This can be done by adding or subtracting velocity components in different directions, while maintaining the magnitude of the velocity vector.
Which characteristics of motion could change without changing the velocity of an object?
Some characteristics of motion that could change without changing the velocity of an object include acceleration, direction, and position. For example, an object moving in a circle at a constant speed has a changing acceleration (centripetal acceleration), changing direction, but constant velocity. Similarly, an object can change its position while maintaining a constant velocity if it moves along a straight path.
If an object has a constant velocity then it?
If an object has a constant velocity, it means it is moving in a straight line at a steady speed without changing direction.
What is the description of the velocity field in a fluid that is incompressible?
In an incompressible fluid, the velocity field describes how the fluid moves without changing its density.

Is changing direction really the same as changing speed?
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
Is it possible to change translational kinetic energy of an object without changing it rotational energy?
Yes, it is possible to change the translational kinetic energy of an object without changing its rotational energy. Translational kinetic energy depends on an object's linear velocity, while rotational energy depends on its angular velocity. By adjusting the linear velocity without changing the angular velocity, you can change the object's translational kinetic energy without affecting its rotational energy.

In an incompressible fluid, the velocity field describes how the fluid moves without changing its density.
When do speed and velocity become equal?
Speed and velocity become equal when an object is moving in a straight line without changing direction or when it is moving at a constant speed. Velocity is a vector quantity that includes both speed and direction, so if the direction of motion is constant, speed and velocity will be the same.
Can you have velocity without acceleration?
Yes, a body can have aceleration without velocity. Consider sin x the position; cos x is the velocity and -sin x is the acceleration. Here the acceleration negative when x=90 degrees and the velocity is zero at 90 degrees.
What does constant velocity or acceleration mean?
"Constant" means that regardless of when you measure it, the result is always the same. "Velocity" means speed and its direction. "Acceleration" means the rate at which speed is changing, and the direction in which it's changing.
Can the velocity of a body be constant still varying its speed?
Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.
What is a graph of uniform velocity?
A graph of uniform velocity would be a straight line with a constant slope, indicating that the object is moving at a constant speed in a straight line without changing its velocity.
