Answer 1
m/F

INCORRECT

Acceleration equals the rate of change of its velocity.  return to top























Answer 2
v/t

CORRECT

Acceleration equals the rate of change of its velocity.  return to top



























Answer 3
mv

INCORRECT

Acceleration equals the rate of change of its velocity, the answer 3 formula equals the change of momentum of an object.  return to top


























Answer 4
2s/t

INCORRECT

Acceleration equals the rate of change of its velocity.  return to top


























What's this question really asking?

The formula for change of velocity of an object, (acceleration.) return to top
