every snap. Mass, force, momentum, velocity and torque all play significant roles in the tackling action performed by players and the better you understand these terms the better you can begin to understand the game itself (Gay). Most of what football players and coaches know about tackling is more instinctive than anything. They understand more about the physics of the process more than they realize. Force, mass, acceleration, momentum, torque, velocity, inertia and center of mass are important

Universe started leaving room for future discoveries to fill in the blank. The law of conservation of linear momentum states that the total momentum of a closed system of objects is constant. One of the consequences of this is that the center of mass of any system of objects will always continue with the same velocity unless acted on by a force from Cannon 2 outside the system. Galaxies are found at varying distances, moving in different directions at different velocities and almost always in

Unit 8 Assignment 1 20. Because the magnetic force which deflects the electrons is defined by F = q * v x B (v x B is the cross product of the 2 vectors), so: The force vector would always be perpendicular to both the v and B vectors. Since the force is perpendicular to the electron's velocity vector, and thus the path of the electrons, the work done by the field on the electrons is 0, because W = F*d*cos(theta), and theta=90 degrees, therefore cos(theta)=0, and W=0 If W = 0 then

support force does the left pier provide? 5. Tasha has mass 20 kg and wants to use a 4.0-m board of mass 10 kg as a seesaw. Her friends are busy, so Tasha seesaws by herself by putting the support at the system's center of gravity when she sits on one end of the board. How far is she from the support point? 6. An 80-kg man is one fourth of the way up a 10-m ladder that is resting against a smooth, frictionless wall. If the ladder has a mass of 20 kg and it makes an angle of 60 with the ground,

Examples: An unstable nucleus of mass 17 x 10-27 kg, initially at rest, disintegrates into three particles. One of the particles, of mass 5.0 x 10-27 kg, moves along the positive y-axis with a speed of 6.0 x 106 m/s. Another particle of mass 8.4 x 10-27 kg, moves along the positive x-axis with a speed of 4.0 x 106 m/s. Determine the third particle’s speed and direction of motion. (Assume that mass is conserved) Write down what you know mnucl = 17 x 10-27

therefore remain stationary, with the axis horizontal, without the application of any braking force. It has no tendency to rotate due to the force of gravity. ------------------------------------------------- Dynamic balance A rotating system of mass is in dynamic balance when the rotation does not produce any resultant centrifugal force or couple. The system rotates without requiring the application of any external force or couple, other than that required to support its weight. If a system is

Title: How different springs behave under the influence of same mass depending on the spring constant (k) and connection types (parallel or series)? Summary: This experiment will be carried out to investigate spring constants of different springs by measuring the length of springs under the influence of same mass and different masses, and observe how overall spring constant changes depending on connection types of springs by measuring amount of extension when springs are connected in series and
