  • When Two Objects Collide

    348 Words  | 2 Pages

    Research paragraph Jean-Marc de Villiers When Two Objects Collide Two moving objects, both possessing momentum by the product of their mass and velocity, collide with one another. Within the system created by their collision, there is a total momentum that is equal to their combined mass and the sum of their velocity. The game of pool provides an example of a collision in which one object, the white ball, is moving, while the other ball is at rest. Due to the solid and hard pool balls, and their

    Frick The purpose of the lab was to find the velocity of a brass ball as it left the muzzle of a cannon and nearly immediately collided with a pendulum. This teaches us about the transformation of energies and transfers of momentums in collisions. Background: In this lab we used conservation of momentum, conservation of energy, and pendulums to complete the lab. Momentum is always conserved in collisions regardless of whether or not kinetic energy is conserved

  • The Role Of Momentum In Soccer

    339 Words  | 2 Pages

    In soccer as in most sports we often hear the term momentum. Momentum, another area of interest in physics is measured as the velocity of an object times its mass. If an object is in motion it has momentum. When a player kicks a soccer ball he transfers momentum to the ball and whenever he receives the soccer ball he slows down the momentum of the ball with his feet. The Magnus effect is of importance to soccer players who want to bend the flight of a ball. It explains why a ball curves through the

  • Essay On Kinetic Energy

    being done. Kinetic energy can be passed from one object to another by clashing towards each other. Kinetic energy is a scalar quantity, and also described by magnitude. This type of energy depends not only on its motion but also on its mass. If you double the mass of an object, you double the kinetic energy. The kinetic energy from a moving object is the same as the work that it does while it is being brought to a rest. Forms of kinetic energy are: vibrational, rotational, and translational. An equation

  • Elastic Potential Energy Experiment

    1726 Words  | 7 Pages

    Fair Testing: This experiment will be a fair test as we will control our control variable at our best of our ability. The experiment will be fair as the mass inside the tub will remain the same throughout the whole experiment. This is because if the mass changes, there will be a larger amount of gravitational force acting on the tub which will affect the displacement of the tub. Furthermore, the surface that the tub will be travelling on will remain the

  • Essay On Aerodynamic

    3683 Words  | 15 Pages

    Aerodynamics is a branch of dynamics to the study of air movement together. It is a subfield of fluid dynamics and gas, and the term "drag" is often used to refer to the gas dynamics. The earliest records of the basic concepts of aerodynamics on the work of Aristotle and Archimedes in the third and second centuries BC, but the efforts to find a quantitative theory of airflow develop until the 18th century, beginning in 1726 was Isaac Newton as one of the first in modern aerodynamics mind when he
