Physics/Velocity nd acceleration

Question
Can different bodies have different velocity but have same acceleration

Answer
Yes, absolutely.  If I am in a 2000 kg car (including myself) and apply a force of 200 Newtons then I accelerate at 1 m/s.  It's the same for whatever speed I am going.

If you're moving in a car, for example, and you're moving at 20 m/s, but the car behind you is moving at 22 m/s and you apply your brakes at the same time then the car behind you will pull up on you as it slows down.

Is there a specific application to this question?

Dr. Stephen O. Nelson

Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
