If the momentum of an object changes and its mass remains constant
its velocity is changing
it is accelerating or decelerating
there is a force acting on it
All of the above
The momentum change of an object is equal to the
force acting on it
velocity change of the object
impulse acting on it.
object's mass times the force acting on it.
If Superman at rest in free space throws an asteroid that has more mass than Superman, then which moves faster?
the asteroid
Superman
They both move at the same speed (but in opposite directions)
Skelly the skater traveling at high speed needs a certain amount of force to stop him. More stopping force will be needed if he has
more mass
more momentum
less stopping distance
all of these

larger
smaller
