Which term is defined as the measure of the force of gravity acting on the mass of a substance

The term describing the measure of gravitational force acting on a mass is "weight".

A brick may weigh 6 pounds on earth but the same brick will weigh only 1 pound on the moon. The mass is the same here or there, but the gravitational force on the moon is only one sixth of the gravitational force on earth.

Which of these would you expect to produce the most centrifugal force A spinning arms slowly B spinning forearms arms slowly with biceps tightly at sides C swinging arms fast in circles with arms out

swinging your arms around in circles very quickly

Which of these is the best example of transfer of momentum

Which of what ? There's no list of choices, no examples,

no suggestions, nothing to choose from.
