Which of the following has a mass of approximately one gram?

=force × distance a. work b. velocity c. pressure d. momentum

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
