1. When an object is experiencing "free fall," what is the only force acting upon it?
2. Does the acceleration of a falling object depend on its mass? Explain.
3. What is the rate of acceleration due to gravity on the earth?
4. In what direction does gravity always cause objects to accelerate?
5. If the initial velocity of an object is upward in the positive direction, what must the sign of the
acceleration due to gravity be in a calculation?
6. A ball is thrown straight up in the air.
a. At the peak of its ascent, what is it doing?
b. What is the ball's velocity at this point?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
