Lab on the Relationships of Time, Distance, and Acceleration at Constant Velocity
Initial velocity is the speed and direction in which the object is moving at the beginning of a time interval and final velocity is the speed and direction the object is moving at the end of a time period. Average velocity is the average speed and direction of the object. An example of this is a car starting at rest, facing west has a velocity of 0m/s and after 10s it has reached a speed of 20m/s in a westward direction.
2. Acceleration is the rate at which and object’s speed is changing. It is simply how the object’s speed changes In relation to the time it is taking to do so. An example of acceleration would be when a car begins to move it must increase its speed until it reaches the speed limit where it no longer accelerates.
3. The distance-time graph shows that the distance traveled has a direct proportion to the traveling time. The slope of the graph shows the objects speed, since it is a straight line the object has constant speed. Since the graph is a straight line it tells us that there is uniform acceleration. This can be compared to a car on the highway that is going at a constant speed and does not accelerate. The velocity-time graph shows that there is an indirect relationship between velocity and time. Since the slope of the graph is roughly zero this means that there is no acceleration.
Through this lab we were to discover the relationships of time, distance, and acceleration at constant velocity.
To complete this we lab we used a spark timer, a sparker, timer tape, and a meter stick.
The lab began with having Joe place his foot in front of the truck while Bob turned on the sparker. When Joe moved his foot the truck moved with the stream of tape following it. Once the tape had completely passed through the sparker we took the tape to a lab table and began to measure. We looked for the second readable dot and considered it zero. Since the sparker emitted a spark .2 seconds we circled every fifth dot and measured the distance between our zero and the circled dots. To find displacement we measured one dot around each circled dot and subtracted the two numbers.
Acceleration and velocity are mostly dependent on the number of dogs, the quality of the dogs, and how well the dogs have been trained, but it also can depend on friction and inertia. The lager mass an object has the the more weight it has and the more inertia it has.
4. How would you explain your results using the terms: impulse, momentum, force, and time? Use equations to help you explain the results.
On Tuesday in lab, we wanted to measure the velocity and acceleration of a ball rolling down an incline. To do this, we made our table have an incline by putting wood blocks under two legs of the table. We placed meter sticks on a table so we could determine the distance the ball traveled for a certain amount of time. We placed the ball at the 0cm mark on the meter stick and let go of the ball so it could roll down the table. To make our results more accurate, we videoed the ball rolling down the table with a stopwatch on our phone following the ball. We then went through the video and paused it at every 10cm and recorded the time it took for each 10cm interval from 0cm to 150cm. We did this experiment with 2cm, 4cm, and 6cm inclines to show
Einstein’s Special Theory of Relativity has had a colossal impact on the world and is the accepted physical theory reg...
Beside its contribution to physics Einstein’s relativity also offered so many scientific bases for some breakthroughs and new technologies. We can divide the influences into two aspects.
• The first is the Special Theory of Relativity, which essentially deals with the question of whether rest and motion are relative or absolute, and with the consequences of Einstein’s conjecture that they are
The materials used in this lab were an inclined plane, a block of wood, a set of weights, pulley, weight hanger, and a computer. In the first part of the lab, my group and I placed the plane in a horizontal position and the block on the plane and put the attached string over the pulley along with the hooked weights. We adjusted the pulley so that the string would be parallel with the plane. Then, we added weights until the force was sufficient to get the block moving. We repeated this procedure four times adding 100 grams every time. After each time, we plotted the graph on the computer. In the second part of the lab, we used the inclined plane to elevate it to the extent where the block would slide without any external force on it. We repeated this process while recording the angle of the plane and elevating the plane higher and higher. We used this data to determine the coefficient of static friction.
This equation shows that mass will not affect the speed of an object, proving that whatever the mass of an object, the speed will always remain the same if all the other factors are kept constant.
Kinematics unlike Newton’s three laws is the study of the motion of objects. The “Kinematic Equations” all have four variables.These equations can help us understand and predict an object’s motion. The four equations use the following variables; displacement of the object, the time the object was moving, the acceleration of the object, the initial velocity of the object and the final velocity of the object. While Newton’s three laws have co-operated to help create and improve the study of
The definition of a projectile is an object that the only force acting on it is gravity. Projectile motion is the path the projectile takes. We saw and used this topic a few times in our project. The first time we saw it was when the marble was flew out of the pipe and was in the air. The second time we used the topic to make sure the trains fell on the lever in the correct spot so the golf ball would roll. The third time it was used, was when the board fall on the balloon. It fell as half of a parabola since it started standing up.
In 1905, Albert Einstein wrote his paper on the special theory of relativity (Prosper). This theory has the reputation as being so exotic that few people can understand it. On the contrary, special relativity is simply a system of kinematics and dynamics, based on a set of postulates that is different from those of classical mec...
Special relativity is a theory that has been accepted by physics as a theory relating to the relationship between space and time. This theory is really important to physics, and all physics teacher such as yourself because special relativity explains the observed fact that the speed of light stays and remains constant regardless of the direction or velocity of its motion. Special relativity now plays an important role in astronomical observation. Special relativity is more precisely about speed. To be even more precisely this speed deals with 299,792,458 ms-1, which is the speed of light, or the rate at which light travels (in meters) per one second.
There are five critical parts to understanding projectile motion and what it is: acceleration, velocity, displacement, maximum and minimum height, and the vertical and horizontal components.
The first way is that you accelerate away from a location that we will refer to as “at rest”, by accelerating back towards them you have effectively “skipped” a portion of time. This is due to spacetime being in balance so having such a large displacement of space means that time must move slower to balance that. Since the amount of time that has passed for you is less than the amount that passed for the location “at rest”. That now matches our definition for time travel and as such you have now traveled to the future. The second way that time dilation can occur is through being inside a strong gravitational, it has been observed that the passage of time in a strong field when observed by someone in a weaker field would be slower relative to the observer in the weak gravity field. This, by our definition of time travel, is an example of peering into the past or by entering that field entering the relative past.
