If an object travels at a constant velocity, what
can we say about its acceleration?
What is another situation where an object
could have no acceleration?
When solving for acceleration, you can have
answers that are positive OR negative.
What does a positive answer mean?
What does a negative answer mean?
An object moving with a negative velocity and a positive acceleration would be what?
speeding up in a negative direction or slowing down in a negative direction or speeding up in a positive direction or slowing down in a positive direction and why?
Thank you.
Does a negative acceleration always mean that an object is slowing down?
Yes or No
Explain.
