An object is released from rest on a planet that has no atmosphere. The object falls
freely for 3.85 m in the first second.
What is the magnitude of the acceleratio
due to gravity on the planet?

If the textbook weighs 19.6 newtons on venus,what is the strength of gravity on venus?

Contrast the force of gravity between these pairs of objects: 1-kg mass and a 2-kg mass that are 1 m apart; a 1-kg mass and a 2-kg mass that are 2 m apart; and two 2=kg masses that are 1 m apart. i dont understand.
