Question

When an object moves, stops moving, changes speed, or changes direction, how do scientists describe that condition?

Answer 1

next time please post the answer choices

A.
stable factors

B.
frictional force

C.
a balanced set of forces

D.
unbalanced forces

Answer 2

with that said, if an object changes its movement speed and/or direction, it's accelerating.

now, thinking about Newton's second law F = ma, if the acceleration is nonzero, what does that say about the net force?
