so your car doesnt roll down the hill
It is moving either one way or the other. Linear motion is straight line motion. Either the object is moving toward point A or away from it toward point B.
The reference point should be stationary, or not moving.
1. Verification questions - These are basic data collecting questions. They are useful in building knowledge.Examples are: Is it cold today? Is the sun still out? Is a flame hottest when it is blue?2. Significant/Theory questions require an explanation and prior knowledge - Examples are: Why should you point a car's wheels toward the curb when parking on a hill? Do clouds have to be in the sky for it to rain? Why do you add acid to water instead of water to acid? These questions increase knowledge of the subject, but need prior knowledge to be asked3. Experimental questions require explanations, prior knowledge, and are testable - Example: If salt is added to water, would the solution still boil at the same temperature? or If Suntan lotion is put on ultraviolet detecting beads, will the beads still change color? Experimental questions require a more in depth answer that requires testing. Experimental questions are what researchers use.
hold the compass flat, the needle will point North-South. Twist the outer ring until N aligns with the north pole of the magnet. Turn until you are looking toward whatever you want a heading toward. look over the compass toward the hill, house, whatever landmark of which you want a heading. look at the dial and estimate the bearing of that object.
In a graduated cylinder, the water or liquid will tend to pull its surface up the side just a bit. This curved shape is call the meniscus. You should read the level at the lowest point of the meniscus, in the center. Turn the cylinder so that the markings are toward you, so you can see the low point of the meniscus behind the markings to get your measurement. There are a few liquids which want to pull away from the edges, which will thus have an inverted meniscus. For these, you would read the high point.
Toward the shoulder. If you are parked on the right side of the road.
To the right.
You should point your wheels away from the curb when parking up hill and toward the curb when parking down the hill. You want the vehicle to immediately make contact with the curb if is rolls.
When parking downhill, whether there is a curb or not, always point your wheels toward the curb or the edge of the road. This way, if the vehicle begins to roll, it will be directed toward the curb, preventing it from rolling into traffic. If there is no curb, turn the wheels toward the roadside to minimize the risk of your vehicle rolling into the path of other vehicles.
they do that so it does not roll down hill
Turn your wheels to the left.
Your wheels should point into the curb, so if vehicle rolls it will stop on the curb .
If you normally drive on the right side of the road, turn your wheels to the right.
Wheel chocks are an important safety measure to keep the car from rolling while you are working on it, should the parking brake fail or not be set. In addition, many cars only have parking brakes on the rear wheels, and it can be necessary to chock the front wheels in order to jack up the rear of the car.
set the parking brake, turn off the ignition switch and put the vehicle in low gear if your transmission is standard, and park, if it is automatic. The wheels should not be over twelve inches from the curb.
No more than it would harm parking it facing downhill. Makes no difference really. Just make very certain that you do these things when parking:* always point the wheels away from the curb when facing uphill * always point the wheels toward the curb when facing downhill * always set the parking brake while your foot is on the brake and BEFORE putting into Park on automatic transmissions. Applying the parking brake should be done every time regardless of the terrain. If one gets into the habit of doing this all the time, then it will become automatic. The little pin in the transmission is all that is holding the car from rolling ... use the brake, too. It will help greatly when you are trying to get the transmission out of Park when on a hill if the parking brake has not been used.Manual transmission people always use the parking brake (handbrake) anyway, so it is something we do without thinking. A good habit for everyone.
If you are parked on level ground or facing downhill, you should turn your wheel towards the curb, so that the front of the tire is facing the curb. This way, if your car begins to roll down the hill or is struck from behind, it will be forced into the curb. If you are parked facing up a hill, you should turn your wheel away from the curb, so that the back of the tire is facing the curb. This way, if your car begins to roll down the hill, it will be forced to stop on the curb. Always apply your parking brake when parking on a hill.
