will turn into gravitational force. To make the pachinko board we will need a nail gun and a 6”x 24” peice of plywood. For the second step (step b) the marble will fall onto a set of incline planes attached to the peg board background. The marble will roll down with rolling force and kinetic energy. For this step we will need three 8” pieces of pvc piping. For the third step (step c)the marble will hit a large marble at the end of the last incline plane using net force and gravitational potential

inertia. An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. That affected my roller coaster by the hill and the loops by the roller coaster making it go down a hill and then the loops using speed as force for it to move. Also the weight of the roller coaster suddenly going from the hill to the loops without stopping

everyday sense of the word. 2. Work is defined as a force causing a displacement. Work = force x displacement W = Fd 3. Work is NOT done on an object unless the displacement is greater than zero 4. The only forces that are considered to do work are those that are parallel to the displacement. 5. For this reason we use our trigonometric functions to calculate forces applied at an angle. Insert Fig

Chapter 2 lesson 1 How are forces described ? In sciece the word push or a pull when one object pushes or pulls another object the first object exerts a force on the second object you exert a force on a computer key when you push it you exert a force on a chair when you pull it away from a table like velocity and acceleration a force is described by its strength and by the direction in which it acts pushing to the left is a different force from pushing to the right the direction

study the motion of objects in the real three-dimensional world we are well prepared for that undertaking. The case studies in this chapter include motion when the net force is constant (we study the local gravitational force near the Earth), one-dimensional motion of an object in a fluid (where we show that there are frictional forces that vary with time), and the oscillatory motion of an object attached to a spring. After learning something about springs, we next consider the deformation of an elastic

Galileo was born in Pisa (then part of the Duchy of Florence), Italy in 1564, the first of six children of Vincenzo Galilei, a famous lutenist, composer, and music theorist; and Giulia Ammannati. Galileo was named after an ancestor, Galileo Bonaiuti, a physician, university teacher and politician who lived in Florence from 1370 to 1450. Galileo Galilei was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the scientific revolution. Galileo has been called

then the ne t force applied to the car is zero. B) An object cannot remain at rest unless the net fo rce acting on it is zero. C) An object has constant acceleration if the net force acting on it is constant. Understanding Newton’s Laws A) An object cannot remain at rest unle ss the net force acting on it is zero. B) If a block is moving to the left with constant ve locity the net force applied to the block is zero. C) A block of mass 2 kg is acted upon by two forces: 3N (d irected

real experiment: Forces of friction and gravity act on the ball so it rolls just short of the same height. In an ideal experiment: Ball rolls infinitely In a real experiment: Once again, forces of gravity and friction act on the ball to slow it. ------------------------------------------------------------------------------------------------------------------------------------------ Experiment 2 Cup has 0 net force. No gravity, No friction. An object with 0 net force will keep moving

Name:____________________ Density, Buoyancy, and Force Diagrams PhET Lab (rvsd 2/2011) Introduction You’ve heard that oil floats on water. You also know that ice cubes normally float in a glass of water. Why? What causes some things to float in water (corks, ice, dogs) and some to sink in water (rocks, metal spoons, mobsters)? Density is often described as the amount of mass crammed into a volume, and is illustrated by the formula shown below. The units for density are expressed g/cm3, g/mL
