An object undergoing positive acceleration is either increasing its velocity in the positive direction or reducing its velocity in the negative direction. A car's velocity can change signs when experiencing constant acceleration. For example, it can be traveling right, while the acceleration is to the left. The car slows down, stops, and then starts accelerating to the left.
Sure, the 5-K is friendly, the 10-K classic, and the half-marathon a self-esteem pumping "long distance" race. But none of these has the cachet that is the marathon's alone. From the time you finish your first shorter race, the specter of the 26.2-mile Full Monty hovers in your mind. Something that one day you want to do. Have to do.
[pic] Figure 1. The intersections of five one-way streets The letters a, b, c, d, e, f, and g represent the number of cars moving between the intersections. To keep the traffic moving smoothly, the number of cars entering the intersection per hour must equal the number of cars leaving per hour. 1. Describe the situation.

Lab 13 Relativity Purpose: The purpose of this laboratory activity is to gain familiarity with the terms and phrases used in relativistic physics and to compare relative motion scenarios at everyday speeds with motion near the speed of light (c). Materials: Ruler, Paper, Pencil. Procedures: 1.Person A is standing in a field, and person B is riding in a car that is moving with velocity (v). The person in the car shines a flashlight in the direction he or she is moving. Question: What speed of light will each person measure?
2. Which law of motion explains what happens during a ride on the bumper cars? Give an example. The third motion, if one body exerts a force on a second body, the second body exerts a force equal
Be sure to explain: a) The direction the man is moving – toward or away from home. (This may change within one graph.) b) His speed – fast, moderate, slow. (Again, this may change within one graph.) c) The rate of change: Is he moving at a constant rate or his is speed changing as time goes on.
For example, if a particular isotope has a half-life of 20 yr, and the starting amount of the isotope is 100 mg, how much of the isotope will be left in exactly 100 yr? To solve this problem, we first make a chart containing the information we know. time |0 yrs | | | | | | | |amount |100 mg | | | | | | | | Since the half-life is 20 yr, each time interval in the chart should add 20 yr to the previous interval until the time of 100 yr is reached. time |0 yr |20 yr |40 yr |60 yr |80 yr |100 yr | |amount |100 mg | | | | | | | Since the time represented by each interval is the half-life of the isotope, the amount of the isotope must decrease by 1/2 for each interval. For instance, at the end of the first 20 yr interval, the amount of the isotope would decrease by 1/2 to 50 mg.

Reducing pressure has opposite effect, gasses expand and so reaction is less vigorous. http://staff.um.edu.mt/jgri1/teaching/che2372/notes/10/10_16.gif (Collision photo) http://www.roadcover.co.za/wp-content/uploads/2011/09/car-crash-wallpapers_5294_1024x768.jpg (another collision photo) Hypothesis For a hypothesis a plastic cart was placed on a ramp which lead down to tracks. Then a meter ruler was placed next to the track , and a block was placed on the track. Then marked where the block remained using a marker, then released the cart to hit the block causing a collision. Then a cylinder was placed after writing down the results(On a numerical table) of how far the block was pushed from the marked spot.
