In the case of this car, a negative position means the car is going backwards and is on the other side of the reference point (the reference point is on the positive side). It also means that the velocity is negative as well. (b) What is the physical meaning of a negative slope on a position-time graph? The physical meaning of a negative slope on a position-time graph is that the velocity is negative. In this case with the car in uniform motion, the car is travelling at a constant velocity in a negative (backwards) direction. (a) Sketch a velocity – time graph of the car’s motion for both data tables. Image (b) Determine their slopes. Include units. Slope= 100.9 cm/s [Fwd] Slope= -101.86 cm/s [Bwd] (c) What is the physical meaning of the slope of a velocity-time graph? The slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with a velocity of +4 m/s or changing its velocity by 4 m/s, then the slope of the line will be +4 m/s which is the acceleration of the object. In this case the acceleration would be 100.9 cm/s when going in the positive direction and -101.86 cm/s when going in the negative direction or to the left of the
A 1996 Ford Mustang next to my car revs the engine and my mind loses interest in the squirrel and moves to the cars next to and opposite of me. There are two cars, a BMW and an old pickup truck; the name is not visible. You can see the eagerness of each car; the impatience in these cars is more than of child the day before their birthday. These cars remain perpendicular to the lanes but are moving freely to their destination and seem to be mocking the stationary cars at the red light. The BMW reacts by slowly creeping up as close to the edge of the intersection as possible.
Some where out there in the world, is a person who believes that driving a car in all four seasons is a piece of cake. But we all know thats not the truth. When it comes to both Winter and summer, they both have different temperatures and road conditions. In this paper I will be comparing and contrasting driving in both winter and in summer.
4. How would you explain your results using the terms: impulse, momentum, force, and time? Use equations to help you explain the results.
... : The difference in slope is positively correlated with a lower temperature. This slope becomes apparent
By using negative diction, the the author is saying that everything… For instance, in the text it states
The velocity of the rock at any given point can be determined by adding it's translational velocity at the center of mass (the orange arrow) with it's rotational velocity.
First and foremost it is important first to consider when and also how cars are referenced throughout the story. The first time a car is mentioned

Now To talk about the forces that allow the car to move. There are two main aerodynamic forces acting on any object moving through the air. Lift is a force that acts 90° to the direction of travel of an object. Usually we think of lift when we think of an airplane. The plane travels forward (horizontally), and lift acts 90° to that motion of travel –

The gradient of the graph tells us whether the different rate curves have the same relation, meaning if they have a similar rate of reaction. Reactions can take place in a variety of customs; they can bee steep or steady. The steeper the slope, the faster the reaction takes place. The steadier the slope, the slower the reaction takes place. Aim:

The average driver doesn’t think about what keeps their car moving or what keeps them on the road, but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in reasonable control.
Logan was on his way home from an evening at the local bar. He and some friends had gone out to have a couple beers. As he sped down the road, he blinked vigorously to try to clear his vision. Although it was a perfectly clear summer night, Logan’s vision was blurred from the alcohol. “As long as I keep this car on my side of the road, I’ll be fine,” he thought to himself. He was doing a decent job of obtaining control over the vehicle, or so he thought. Only three miles from his country home, he became unaware of his position on the road as it began to curve. As he continued around the familiar curve in the road, a truck came out of nowhere at hit Logan’s small Toyota Camry head on. The big F-350 pickup truck was no comparison to the little
Here, we can use the vectors to use the Pythagorean Theorem, a2 + b2 = c2, to find the speed and angle of the object, which was used in previous equations.
