Students can also make their pinball machine themed with vinyl decals if time, materials and equipment permit. Add cardboard ramps, cardboard obstacles, or small toys around the board to create obstacles or rebound surfaces.Glue the strips around the perimeter of the board.These sides will keep the marble on the playing field. Cut some long strips of cardboard to make the 4 sides.This is usually 18-24 inches long and 13-16 inches wide. Cut a rectangle out of corrugated cardboard to the desired size.Step Two: Making the base (Time 30-60 minutes) com /open?id=0B3tPBZnliO7bX1Q4bWY2ckhHWjg Adhesive Vinyl (for extension activities)ĭesign Files.Vinyl Cutter (for extension activities).Paintbrushes and paints (for decoration).Large popsicle sticks or paint stirrers.This is a constant and always applies, except in space. The Earth exerts a force on you of 9.8 m/s2. GRAVITY = Force of attraction between the two bodies of matter due to their mass. Energy is our potential to do some type of work. Law of Conservation of Energy = Energy cannot be created nor destroyed. The answer to the problem will be in JOULES of energy You will convert your mass to a FORCE in Newtons (N), then move the mass a certain distance in meters. You will use the formula for Newtons (N) (X) distance in meters (m) equals JOULES (J). (N) Work is done only when FORCE causes a change in the motion of an object. (W) WORK is the amount of FORCE needed to move an object a certain distance. The bell crank on your pinball machine transfer horizontal force to vertical force.A bell crank is a lever with two arms that have a common pivot at their junction.In turn the load is larger while the distance moved is smaller. The effort needed to lift a load is decreased, however the distance is larger.Levers involve moving a load around a pivot using effort.A lever is a simple machine that makes work easier for use by decreasing the force required to do work.The force of gravity accelerates the ball down the incline of the pinball machine.The flipper in the pinball machine changes the marbles’ speed and direction of motion.Force is a push or pull on an object which changes direction of speed of motion.Stored energy can be converted to motion by releasing a spring or rubber band. Stored mechanical energy can be seen in rubber bands that are stretched. Kinetic energy is the energy of motion and potential energy is stored energy. There are two types of mechanical energy: kinetic and potential.If you think energy has ‘disappeared’, it has not has been converted to a different type of energy. The Law of Conservation of Energy states that energy can neither be created nor destroyed.Energy is defined as the capacity of a physical system to perform work.Work, Joule, Power, Energy, Lever, Pulley, Force, Motion, Mechanical Energy, Potential Energy, Elastic Potential Energy, Chemical Energy, Gravitational Potential Energy, Kinetic Energy, Work-Energy Theorem, Law of Conservation of Energy, Machines, Efficiency, Watt, Horsepower Instructional Design : Confirmation Inquiry Level 3 For these reasons, energy plays a central role in the high school science curriculum. It is essential for explaining a wide range of phenomena, solving problems that occur in everyday life, and learning other science ideas. Energy is a critical concept across all science disciplines and as such serves as both a disciplinary core idea in multiple disciplines and a crosscutting concept. The concept of energy is often introduced in the very first unit of 9th grade Conceptual Physics. There are two ways that beginning students of physics can understand the topic: (a) through mathematical models, and (b) through concepts. By end of lesson, students will be able to design and build a digital fabrication pinball machine that will use at least one form of energy.Ĭonceptual Physics presents concepts of the major themes of physics. As students explore digital fabrication tools to design a pinball machine, they will gain an understanding of the applications of potential, kinetic and mechanical energy through simple and complex machines. All mechanical energy is classified as either kinetic or potential.
