Introduction: Gravitational Forces

More Details: -Explain how a careful analysi of the motion of an object falling close to the Earth's surface leads to the conclusion that there must be a gravitational force of constant magnitude acting on the object in a direction toward the ground. (HINT: Carefully describe the motion, and use Newton's laws i your explanation.)-Explain how careful analysis of the motions of two objects of different mass falling close to the Earth's surface leads to the concusion that the gravitational force is proportional to the mass of an object. (HINT: Carefully describe the accelerationsof the objects, and use Newton's laws in your explanation.)
