* Constant speed: The object covers the same distance in the same amount of time throughout its motion.
* Constant direction: The object's path is a straight line without any changes in direction.
Examples of uniform velocity:
* A car traveling at 60 miles per hour on a straight highway.
* A ball rolling across a smooth, flat surface at a steady pace.
* A satellite orbiting the Earth at a constant speed and altitude.
Key points to remember:
* Uniform velocity is not the same as constant speed. An object can have constant speed but changing direction (like a car going around a curve), which means its velocity is not uniform.
* Uniform velocity implies zero acceleration. Acceleration is the rate of change of velocity, so if velocity is constant, acceleration is zero.
Here are some ways to tell if velocity is uniform:
* Looking at a graph: A velocity-time graph will be a horizontal line if velocity is uniform.
* Observing the motion: If an object moves at a steady pace in a straight line, its velocity is likely uniform.
Let me know if you'd like more examples or explanation on how to determine uniform velocity!
