The first part of this document derives the equations needed for the lab from the definitions of average velocity and average acceleration for the PY205N method. This is followed by a section deriving from the principles of motion the same equations as in the 205M method

Derivation of Average Velocity and Acceleration – PY205N This discussion deals with the motion of an object under the influence of a uniform acceleration (eg gravity at rest). In the following derivations, downward is taken as the positive y direction, but this is only a convention. Any direction can be positive as long as all the upward vectors are opposite in sign to the downward vectors (in other words, just remain constant). Average velocity and average acceleration Consider an object in position y1 at some initial time t1. At the next time, t2, the object is at y2 The average speed of this object as it moves between these two points is v 12 Similarly, the average velocity during the next time interval v is 23 (ie between instants t2 and t3).

### Solved At T1 = 5.00 S, The Acceleration Of A Particle Moving

If the acceleration is uniform or constant, the instantaneous velocity at the midpoint of the time interval is the average velocity. Although the acceleration is not the same, it is closer if the time interval is shorter Thus v occurs in the middle of the time interval given by 23

Where Δ v and Δ t represent the change in velocity and time respectively Motion Graph For an object moving at constant velocity, the distance versus time graph is a straight line with a constant slope, as in the graph in Figure 1a below. Since distance is plotted on the vertical axis and time on the horizontal axis, the slope is Δ(distance) Δ(time), or average speed. Here, the average speed is equal to the instantaneous speed at any point in time

Figure 1b shows the position versus time plot of an object moving with increasing speed. Here we can draw a graph where we connect the points with a solid line, shown as the red line in Figure 1b. When we measure the position of an object at small time intervals, we see a smooth curve, as shown by the blue curve. The average velocity between the two points (x1, t1) and (x2, t2) is given by the slope of the line connecting the two points. Now consider the velocity versus time version of this graph, shown in Figure 2. The average velocity intersects the instantaneous velocity at the midpoint of the two time scales. The average of the two points is the midpoint of the two points So if we take the average of t2 and t3, we get half the travel time Here we call this time t23 As shown in figure 2, the instantaneous speed and the calculated average speed are the same at this averaging time t23. Therefore, we use average time and average speed to calculate acceleration

Kinematic Equations Kinematic equations are derived from the definitions of average velocity and acceleration discussed above for uniformly accelerating objects. These equations provide a useful way to estimate the motion of moving objects with constant equations For one-dimensional motion, the kinematic equations are

#### What Is The Difference Between Velocity And Acceleration?

Where vi and vf are the initial and final velocities when the object is at positions xi and xf, respectively, Δ t is the elapsed time, and a is the constant acceleration of its motion. When a freely falling object is released from rest, vi = 0. The downward acceleration is equal to g (defined as positive at the beginning of this discussion), and the total displacement is equal to the downward and upward displacements. The object falls (suppose the object falls to the ground). Making these substitutions in Equation 6 gives the following form

Derivation using the principle of moments – for an object in free fall at a height of 205 m, the only force acting on it is the gravitational force. (For this experiment, we ignore air resistance.) At the Earth’s surface, the gravitational force can be approximated by FEarth = 0, −mg, 0, where g ≈ 9.81 m/s2. So we can determine the effect of this force by the principle of motion

In what follows, we will only consider the y-components of the equation, since the other components have no net force. We replace p by mv, taking γ = 1 to be the velocity that the object also acquires Since the mass of the object appears in each term, it can be canceled out, leaving an equation corresponding to 5 v f = .
