1. Acceleration and trajectories
- carini.physics.indiana.edu
- Acceleration and trajectories.
- We can find out about forces acting on a particular object by watching its motion and finding its acceleration. To find the acceleration, we first had to understand how to find velocity (see last Friday's notes and the exercises) and then to understand how to find changes in the velocity almost everything we do in analyzing motion involves using this skill . The acceleration vector.
- Now would be a good time to define the acceleration : a = Dv/Dt in words, the acceleration is the change in velocity divided by the change in time. To picture the acceleration, we need to find out how to find the difference between the velocity vectors (mathematically, we are subtracting the vectors,finding the difference between two vectors is the same thing). ...
- The acceleration vector.
- Notice the difference between the acceleration vector and the change-in-velocity vector. The acceleration vector points in the same direction as the change-in-velocity, but it's length is different: it tells us how fast the velocity vector is changing while the change-in-velocity vector shows how much the velocity changed from one particular time to another particular time . ...
- Note that if the two vectors are the same, then the difference is zero, which means that the acceleration must be zero for any trajectory with uniform motion (since all the individual displacement vectors are the same): Uniform motion <=> velocity is constant <=> acceleration is zero According to Newton's Second Law, the total force acting on an object undergoing uniform motion is zero (this does not mean that there are no forces acting on that object, just that they are in balance so that the total force is zero). Acceleration for non-uniform motion.
- In sports, the motion is almost always nonuniform, so the acceleration is not usually zero. ...
- Notice that for a speeding up trajectory involving motion along one axis, the change in velocity (and therefore the acceleration) point in the same direction as the velocity vector; for a slowing down trajectory (part b), the the change in velocity (and therefore the acceleration) point in the opposite direction from the velocity vector. For the changing-direction trajectory (part c), the change in velocity and the acceleration point mostly perpendicular to the velocity vector. In part d, both the direction and magnitude of the velocity change, so the acceleration points somewhat along the direction of the velocity vector and somewhat away from it. ...
- Unlike its everyday meaning (speeding up), in physics acceleration refers to any change in the velocity vector: .

- Acceleration is one of those words for which we have a common meaning and a meaning that is specific to the field of physics. Ask the average person on the street and they will define acceleration as "speeding up. " However, this is just a portion of the full meaning of acceleration as used in physics. In physics, acceleration is defined as a change in velocity. ...
- Mathematically, we can express acceleration with the following formula:.
- a - acceleration.
- The value for acceleration may be a negative or positive value depending on magnitude of vf and vo, but it is still properly termed acceleration (although we do often call negative acceleration "deceleration").
- The unit for acceleration takes the form of.
- where the time unit for velocity matches the time unit in the denominator of the acceleration formula. ...

6. Vectors: Velocities, Accelerations, and Forces
- csep10.phys.utk.edu
- In order to understand the discoveries of Newton, we must have an understanding of three basic quantities: (1) velocity, (2) acceleration, and (3) force. ...
- Velocity and Acceleration.
- Let us now give a precise definition of velocity and acceleration. ... The velocity v and the acceleration a are defined in the following illustration, .
- This illustration also demonstrates graphically that velocity (and therefore acceleration) is a vector: the direction of the rock's velocity is certainly of critical interest to the person standing under the rock in the two illustrations! Uniform Circular Motion is Accelerated Motion.
- Thus, acceleration occurs when either the magnitude or direction of the velocity (or both) are altered. ...
- In particular, notice from the adjacent image that circular motion (even at uniform angular velocity) implies a continual acceleration, because the direction of the velocity (indicated by the direction of the arrow) is continuously changing, even if its magnitude (indicated by the length of the arrow) is constant. ...
- Be aware that in popular speech acceleration is assumed to be an increase in the magnitude of the velocity. As we have just seen, acceleration also occurs when the direction of the velocity is changed, even if the magnitude is constant; furthermore, in physics a decrease in the velocity is just as much an acceleration as an increase. ...

- The formula we will use will figure out average acceleration, rather than instantaneous acceleration. ...
- The formula for finding average acceleration is:.
- 281 feet) is equal to vo (Initial Velocity - for CO2 cars this is 0) multiplied by t (time in seconds) plus one-half a (Average Acceleration - what we are looking for) multiplied by t squared (time in seconds again). ...
- Since we have all the variables for our example except acceleration, we can plug them into this formula and solve for a. ...
- Solving this for a gives us 40, placing the average acceleration of our example CO2 car at 40 meters/sec squared. ...

- Paula: Can you define acceleration?.
- Thomas: Sidney Pressey's definition of acceleration was encountering curricular material at either a faster pace than normal or at ages earlier than normal. For us, I think we can operationally think of acceleration as one of two things: either we move the students through material faster, such as providing two years of mathematics completed in one year, or, we give them advanced content at younger ages, such as providing 9th grade algebra to 6th graders.
- Paula: A lot of people think of acceleration primarily as grade skipping, but one of the points you make in your book about acceleration is there are many different forms of acceleration. ...
- There is content acceleration or subject matter acceleration where a student stays with chronological peers most of the time in school but has material brought to him that is different and more advanced only in the area that she/he is talented. ...
- Another type of acceleration, popular in my home state of Ohiowhich exists by legislation in 22 states across the USis when a student in high school also enrolls and takes college classes. This is also a form of acceleration.
- In many of the options that fit the definition of acceleration, however, the student remains with her/his peer group for much of the time or receives instruction in private settings unobserved by chronological peers.
- Paula: How frequently are acceleration options used by schools with children to accommodate this situation?.
- They also are reluctant to do modifications like content or subject matter acceleration because they do not have a way to manage it. ...
- There are periods of time in history when acceleration has been considered relatively normal. ... Then acceleration became much more favorably viewed again. ...
- Then after the war, during the times of American concern about Cold War issues, acceleration was viewed favorably because we wanted to maximally educate citizens so the US would be competitive with other world powers. ...
