  • Kinetic Energy - 385 Words
    KINETIC ENERGY Objects have energy because of their motion; this energy is called kinetic energy. Kinetic energy of the objects having mass m and velocity v can be calculated with the formula given below; K=1/2mv² Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric unit of measurement for kinetic...

    History A roller coaster train going down hill represents merely a complex case as a body is descending an inclined plane. Newton's first two laws relate force and acceleration, which are key concepts in roller coaster physics. At amusement parks, Newton's laws can be applied to every ride. These rides range from 'The Swings' to The 'Hammer'. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A...

    When something is able to change its environment or itself, it has energy. When you think of energy, you might think of action- or objects in motion, like the baseball that shatters a window. There are different forms of energy. Turn on an electric light and a dark room becomes bright. Turn on a music player and sound comes through your headphones. In both situations, energy moves from one place to another; effect and reaction. The two different types of energy are kinetic and potential energy....

    Mouse Trap Car The mouse trap car we designed for this project was pretty standard. We used metal rods with rubber wheels attached for the axles and wheels. We supported the axles to the frame using "U" nails. Our wheels featured some spinners as well. For the actual body of the car we glued the mouse trap on another piece of wood to lengthen the body. The mouse trap was hot glued on the top with a extended arm for more leverage. One end of a rope was glued on the extended mouse trap arm and...

  • Study of the Ballistic Pendulum - 2240 Words
    Introduction: The study of the ballistic pendulum began with Benjamin Robins in the early 1700's. Robins was an English mathematician and writer on ballistics, and used this testing apparatus for the evaluation of the strength of gunpowder and the measurement of air resistance (Calvert, 2006). At the time of the American Revolution a loyalist named Benjamin Thompson also utilized and expanded the use to the ballistic pendulum. He further evaluated the efficiency of gunpowder. He fired from...

    Momentum and Simple 1D Collisions PhET Lab Introduction: When objects move, they have momentum. Momentum, p, is simply the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum, p, is kgm/s. During a collision, an object’s momentum can be transferred to impulse, which is the product of force (N) and time (s) over which the force acts. This allows us to write the momentum-impulse theorem: Procedure: Play with the Sims  Physics Motion  Collision Lab Work with 1D...

    Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction, the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system, if no net external force acts on a system of particles, the...
