2.2 Speed and Velocity - Physics | OpenStax
https://openstax.org/books/physics/pages/2-2-speed-and-velocity
Average speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense.

6.2 Uniform Circular Motion - Physics | OpenStax
https://openstax.org/books/physics/pages/6-2-uniform-circular-motion
The figure shows an object moving in a circular path at constant speed and the direction of the instantaneous velocity of two points along the path. Acceleration is in the direction of the change in velocity and points toward the center of rotation.

Jan 20, 2024 · The object is moving at constant speed due to the straight line (uniform) motion. When the slope changes from positive to negative, the direction of the motion changes, but the slope remains the same magnitude.

3.1: Motion in Two Dimensions - Physics LibreTexts
https://phys.libretexts.org/Bookshelves/University_Physics/Physics_(Boundless)/3%3A_Two-Dimensional_Kinematics/3.1%3A_Motion_in_Two_Dimensions
To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion to a straight path. Newton’s second law (\(\mathrm{F=ma}\)) suggests that when a force is applied to an object, the object would experience acceleration.

Speed and Velocity - The Physics Classroom
https://www.physicsclassroom.com/class/circles/Lesson-1/Speed-and-Velocity
Objects moving in uniform circular motion will have a constant speed. But does this mean that they will have a constant velocity? Recall from Unit 1 of The Physics Classroom that speed and velocity refer to two distinctly different quantities. Speed is a scalar quantity and velocity is a vector quantity. Velocity, being a vector, has both a ...

What is acceleration? (article) | Khan Academy
https://www.khanacademy.org/science/physics/one-dimensional-motion/acceleration-tutorial/a/acceleration-article
What does acceleration mean? Compared to displacement and velocity, acceleration is like the angry, fire-breathing dragon of motion variables. It can be violent; some people are scared of it; and if it's big, it forces you to take notice.

Speed and Velocity – The Physics Hypertextbook
https://physics.info/velocity/
Speed is inversely proportional to time when distance is constant: v ∝ 1 t ( s constant) Combining these two rules together gives the definition of speed in symbolic form. ☞ This is not the final definition. Don't like symbols? Well then, here's another way to define speed. Speed is the rate of change of distance with time.

Speed - Physics Book
https://www.physicsbook.gatech.edu/Speed
Nov 17, 2021 · Main Idea. Speed is a scalar quantity that describes how fast an object is moving. It is represented by the symbol v, as opposed to v → and v, which denote velocity. Speed is defined as the magnitude of the rate of change of position with respect to time. In calculus terms, it is the time derivative of distance traveled.

What is centripetal acceleration? (article) | Khan Academy
https://www.khanacademy.org/science/physics/centripetal-force-and-gravitation/centripetal-acceleration-tutoria/a/what-is-centripetal-acceleration
What is centripetal acceleration? Can an object accelerate if it's moving with constant speed? Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.
