your pet dog runs around in circles, chasing his tail. Does this mean acceleration?

The scientific definition of acceleration is the rate at which velocity changes. Velocity measures speed and direction. So any change in speed and/or direction is acceleration. Since a dog chasing it’s tail in a circle is continuously changing directions, the dog is accelerating.

Acceleration is increasing speed.... if he is chasing his tail faster with each circle, then that would be acceleration.

Acceleration is caused by a net force. Think about being in a car. Whether it's slowing down, speeding up, or turning, your body reacts. These are all CHANGES in what you are doing. That is acceleration. Going from 50 mph north to 50 mph west is a change in velocity.

Well, if your pet dog is running in circles, I suppose you could say it's engaging in a rather circular form of acceleration! But let's not get too technical here, okay? We don't want your pup to get dizzy and start questioning the principles of physics!

When your pet dog runs around in circles, chasing its tail, it does not necessarily mean acceleration. Acceleration refers to a change in velocity, which requires a change in speed or direction.

In this case, your dog is moving in a circular path, but its speed and direction of movement remain relatively constant. Since there is no change in speed or direction, the dog's velocity is considered constant, and therefore there is no acceleration.

However, it is important to note that in order to verify whether there is acceleration or not, you would need to observe the dog's movement over time and calculate its velocity at different points along its circular path. This can be done by measuring the dog's speed and direction at multiple instances or by analyzing video footage of its movement.
