vertical motion are independent of each other; that is‚ neither motion affects the other. Acceleration Since there is no acceleration in the horizontal direction velocity in horizontal direction is constant which is equal to ucosα. The vertical motion of the projectile is the motion of a particle during its free fall. Here the acceleration is constant‚ equal to g.[1] The components of the acceleration: a_x = 0 ‚ a_y = -g . Velocity The horizontal component of the velocity remains unchanged

Instructor: (Name) Introduction We verified Newton’s Second Law for one-dimensional motion by timing an accelerated glider moving along a flat track. We varied both the accelerating force and the mass of the glider. We found that for a given force the acceleration of the glider was inversely proportional to the mass of the glider‚ in agreement with Newton’s Second Law. Experimental Procedure Description of the Apparatus: A sketch showing the essential elements of the apparatus is presented in Figure 1. below:

and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that is defined as the rate

come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration‚ force‚ and percent error one will be able to distinguish and evaluate the relationship between the two laws. II. Procedures of experiment: All groups had

(4) using vector equations to represent velocity and acceleration vectors quantitatively. In this activity you will practice representing the motion shown in Figure 1 using vectors and vector equations that represent displacements as well as average velocities and accelerations in the 1/15th of a second time intervals between position measurements.

Part A In the second half of the book Ellie and Graham decide to try being together and start dating. She’s known as the “Unknown Girl” with the paparazzi. Ellie decides to ask her father for money since he is visiting a town nearby Henley with his “regular” family. Graham and Ellie decide to go on a boat over to see her dad‚ even though her dad doesn’t know she is coming. On the way there they run out of gas‚ get caught by the coast guard and drop Ellie’s phone in the water. She ends up running

To improve this‚ the car could have been rolled down the ramp three times and the average of those measurements could have been used for a more accurate result to measure the change in position. However‚ if only the increase in velocity and acceleration are calculated‚ another set of dots that were marked on the ticker tape could have been used as well for trials. A more precise measuring tool could have been used so the measurements would have been much more precise. Other random errors could

He was once a priest until his wife pasted away in a car accident while walking along the sidewalk one night. He gives up being a priest because he believes he was faithful to god his entire life and deserved no such punishment brought to him. Graham does later figure out the signs he
