How would this lab change if you used a heavier object? A lighter object? Explain your rationale for each situation. The acceleration due to gravity is a well-understood physics quantity, with respect to the surface of the Earth. It is determined with knowledge of the mass of the planet, as well as the distance from the center of the planet to a known location. As a global average, it is assumed the acceleration due to gravity is 9.805 m/s2, with slight fluctuations around the poles due to the fact the Earth is not a perfect sphere.

1. Write the final answer for the problem and add the units.   2. Write the claim and reasoning for this problem.   Example of how to write the claim and reasoning is the image with the black background.

Problem-Solving Technique: Draw a labeled picture. Put a coordinate system on the picture indicating the location of the origin and the positive direction. Show the solution in a step-by-step orderly fashion. Write any equation you use in symbolic form before substituting in numbers. 1. Ann is traveling at 30 m/s (80 mi/hr) west when she passes a police car. She immediately begins slowing down at a rate of 2.5 m/s for 4 seconds. How far has she traveled for this time? a. Fill in the information that is given in the problem. Put a question mark for any quantity that is not given in the problem. Vox = v. = b. Determine the distance she traveled in this time. Start with the equation in sy numbers you used including units. olic form and show the

What is the acceleration (in units of feet per second squared) of a car that goes from 15 mph to 75 mph in a 10.0 second time period? How far does the car travel during that acceleration in units of feet? Identify the quantity(variable) you are solving for. make a simple sketch to represent the data given. Make a list of all given values, units, and the variables they represent. Write the general form of the equation you are going to use. Solve the equation.
