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 of revolutions of cycle completed per unit time. So‚ Expressing centripetal acceleration in terms of frequency‚ In

little wide and lose‚ and the flaps were not arrow dynamic what so ever. To improve the flight I could have made my rocket shorter and thinner because the smaller the mass the greater acceleration. Doing this would improve the acceleration of the projectile in this case the rocket. Also to improve the acceleration I could add more alka-seltzer to the film case. Doing this would add a greater force to push off of which would make the rocket go higher and faster. Lastly I could have made the structure

Objective: -To determine and to identify the motion which the metal ball undergoes as it rolls down the acceleration board. II. Materials: Acceleration board‚ cornstarch‚ iron stand‚ clamp with iron bar‚ brass ball‚ PVC pipe‚ meter stick III. Procedure: 1. Using the clamp with iron bar and the iron stand‚ we inclined the acceleration board. 2. We place cornstarch on the acceleration board by spreading and smoothening it evenly that will serve as a mark in order to measure the pathway

distance‚ time‚ and acceleration are all very complex formulas that are interdependent. These formulas are measured in motion data and used to determine the final instantaneous speed‚ distance‚ time‚ and acceleration. Distance and time are two formulas that are used to determine speed and time. For example‚ distance equals speed multiplied with time given‚ time equals distance divided by speed‚ and speed is equals distance divided time. Speed and time are required to determine acceleration. ( This is how

the pendulum‚ and g is the constant of the acceleration from gravity. To calculate an accurate value for g‚ I used 2 values for L on Moon and Jupiter of 2.5m and 1.00m. From there I used the simulation to calculate T and I plugged that into the equation to find g. The average value of g on the moon is 1.606m/s^2. Also‚ the average value of g on Jupiter is 18.913m/s^2. The results are listed in the table below. Location Length(m) Period(s) Acceleration of Gravity(m/s^2) Moon 2.50m 9.022s

the position vector is a function of time. Velocity & Acceleration • Velocity is defined as the change in position over a change in time; thus the average velocity is and the instantaneous velocity is • For motion in one dimension the velocity is the slope of the position line plotted versus time. • The same logic is used in deriving the average and instantaneous acceleration resulting in: • Jerk is defined as the rate of change of acceleration: Example 1 • A body starts from rest at x=0. ax(t)=2t-4

A few of the concepts of physics that take place during volleyball include gravity‚ displacement‚ velocity‚ acceleration‚ projectile motion‚ and force. These concepts are displayed throughout the different positions on the court. There are three main aspects of volleyball that include physics‚ the first one being displacement. This happens when a player moves
