instead of going forward for most of the time. They were still moving at an average speed. For the Sodium solution the Paramecium were moving forward for about 45% of the time. I was observing them. They changed direction frequently going in a jerking motion and a paranoid state (moving backwards.) They were still going at an average speed. For the Potassium solution the Paramecium were moving forward for 58% of the time. The rest of the time they were changing

Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

Nov. 05‚ 2013 PHY10L/A11 Experiment # 2 KINEMATICS Abstract - Kinematics of linear motion is defined as the studies of motion of objects without considering the effects that produce the motion. This experiment will show how to determine the linear motion with constant (uniform) velocity particularly the dynamic cart and linear motion with constant (uniform) acceleration‚ (e.g. free fall of motion). At the end of the experiment we found out that the velocity is a speed that involves direction

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. When the ball is stopped there isn’t any changes

How far does this penny go in 3 seconds? 75 m CONCEPTUAL PHYSICS Chapter 4 Linear Motion 13 Straight Up and Down The sketch is similar to Figure 4.9 in the textbook. Assume negligible air resistance and g = 10 m/s2. • Table 1 shows the velocity data of the figure for t = 0 to t = 8 seconds. Complete the table. Distances traveled are

graph is to describe the acceleration of a free-falling object as being either constant or changing; as being directed upward‚ downward or both (depending on some other variable); and as having a particular numerical value.This lab deals with the motion of an object falling freely (assuming negligible air friction) under the force of gravity. The position of a falling object will be measured as a function of time‚ and its acceleration will be determined from those data. In regard to

Curvilinear Motion Projectile Motion When the player hits the “Sepak”‚ the motion of the “Sepak” is called projectile motion. The “Sepak” itself is called projectile. The “Sepak” will follow a parabolic path called trajectory especially if air resistance is negligible. Two coordinates are usually used to describe projectile motion: horizontal and vertical axes. The horizontal distance traveled by the projectile is called the range. While the vertical distance‚ that is‚ the distance from where

projectile motion. A projectile is an object flying through the air that is only under the force of gravity (neglecting air resistance). A projectile moves both horizontally and vertically‚ which creates a parabolic flight path. In vertical projectile motion there is a constant velocity since there are no forces in the horizontal direction (neglecting drag due to air resistance). Consequently‚ there is no acceleration in horizontal projectile motion. In vertical projectile motion gravity is

Motion and Change Motion and Change two physical displacement features that in turn make up all the physical reality. The rotational motion of electrons and nucleus generate the electrical fields that create all the elements known to man. The amount of neutrons and electrons depends on the elements structure‚ for example water is H2O. Water requires one hydrogen atom and two oxygen atoms this mixture combine creates water.
