photogate. The graphical relationships represented by the graphs show that the Velocity vs Time graph was a linear graph. Linear graphs are when Y‚ which is Velocity‚ is proportional to the X variable‚ which in this case is time. Correlation coefficient of the velocity vs. time graph: 0.9815 Slope is the acceleration of this lab. The slope for the steelie are position in meters per seconds as shown by the graph. The velocity vs. time graph had a slope of 1.599 m/s. Conclusion: Annie Nguyen The purpose

The average velocity‚ which is important in physics‚ can be defined as the change in distance divided by the change in time. When applying‚ the average velocity we are looking at real life application as how quickly air temperature is rising or dropping as a hurricane is approaching. Other application we used the average velocity when you want to know the average rate of speed you ran or travel at a given time. When driving your car you might want to know your average velocity from point A to

Experiment 7: Work‚ Power and Energy Laboratory Report John Karl Macrohon Department of Math and Physics College of Science‚ University of Santo Tomas España‚ Manila Philippines Abstract The experiment is subdivided into two activities: Power and Energy of a Tossed Ball (Physics with Computers). The work done by gravity on each member when going up and downstairs of the second and third floors of the Main Building and the power output of each member of the group in each case was computed

Projectile Motion By Kaneisha Winch Aim: To investigate whether there is a relationship between the horizontal velocity and vertical velocity by using a 7.5 cm baseball in projectile motion. Hypothesis: There is no relationship between the horizontal and vertical velocity. No matter how fast the horizontal velocity‚ the vertical velocity will remain the same. This has no relation to the size or mass of the ball. Materials: • a baseball with a diameter of approx. 7.5 cm • a tape measurer • a surface

initial velocity of the ball shot horizontally from the spring loaded projectile launcher. Also‚ we verified the angle at which the projection of the ball would produce a maximum range. Lastly‚ we predicted the range that a ball would travel at a certain angle‚ theta. Projectile motion is the motion of objects that are initially launched‚ or projected‚ and then continue moving with only the force of gravity acting upon it. The forces involved in projectile motion are the initial velocity of the

the earth curves downward by approximately 5 metres over 8000 metres along the horizon‚ satellites launched with a horizontal speed of 8000 m/s can take orbit. At this speed‚ thanks to earth’s curved surface and a satellite’s constant horizontal velocity‚ the satellites‚ which are in free fall once projected‚ keep falling toward the earth‚ but always miss it. Thus‚ under the influence of gravity‚ satellites maintain motion in a circular pattern at a uniform speed. Most satellites are launched

SOLUTION TO HOMEWORK PROBLEMS Chapter-4: MOTION IN TWO DIMENSIONS 1 A particle starts from the origin at t = 0 with a velocity of 6.0[pic] m/s and moves in the xy plane with a constant acceleration of (-2.0[pic] + 4.0[pic]) m/s2. At the instant the particle achieves its maximum positive x coordinate‚ how far is it from the origin? [pic] 2 At t = 0‚ a particle leaves the origin with a velocity of 5.0 m/s in the positive y direction. Its acceleration is given by [pic] = (3.0[pic] - 2.0[pic])

an object moves at a constant speed along a circular path. Velocity is always tangent to the path in circular motion. Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration. In 1673‚ Christian Huygens‚ determined the following relationships. Velocity‚ Where‚ r = radius of curvature/path‚ t = time/period. Frequency (f) – number

KINEMATICS REVIEW LESSON EXAMPLE 1: Consider the velocity vs. time graph below. The motion of five different people (A‚ B‚ C‚ D‚ and E) are shown on the graph. Study the graph and answer the following questions. Some questions may have more than or less than one answer. Question: 1. Which person(s) changes direction during the time of motion? 2. Which person(s) is/are not moving? 3. Which person has the greatest average speed? 4. Which person(s) has/have a constant‚ positive acceleration
