Module 3: Natural Forces Affecting the Driver Vocabulary: Please define six (6) of the following terms in your own words. Please do not just copy and paste the definition. 1. Gravity- a force that which pulls two objects toward each other. 2.
1. INTRODUCTION Sir Isaac Newton produced three laws of motion. Newton’s second law of motion states that, “the acceleration (a) of an object is directly proportional to the net force acting on it and inversely proportional to its mass” (VUILLE, 86). This second law can be written into mathematical terms and written as: a = Fnet /m However, the equation above is more commonly seen as: Fnet = ma In these equations a represents the acceleration of the object, m is the objects mass Fnet represents the vector sum of all the forces acting on the object. The Atwood machine is an apparatus that explores the idea states above.
2 Basic principles of Kinetics are the “law of inertia” and the “law of energy.” Sir Isaac Newton “The law of inertia” also known as Newton’s 1st law helps explain what happens during blunt trauma. 1. “A body in motion will remain in motion unless acted upon by an outside force.” Example- 2 cars moving at 55 mph, 1 car stops at the red light, car 2 crashes into a wall. An outside force stops the motion of both cars with very different results. 2.
Lubricated friction is a type of fluid friction where a fluid separates two solid surfaces. Skin friction is one of the components of drag. Drag is the force resisting the motion of a solid body through a fluid. The last kind of friction is internal friction. This is the force resisting motion between the elements making up a solid material while it undergoes deformation.
As the athlete is spinning the hammer in a circle there is force acting upon it and that mean Newton’s Laws are relevant to the situation. The circular movement of any object depends on the three Newton’s Laws. 1. If a body is at rest, it will remain at rest unless the forces acting upon it become unbalanced. 2.Force is equal to mass times acceleration.
There are many different kinds of energy. Mechanical energy deals with things in motion. Like all energy, it comes in two forms, kinetic (the energy of motion) and potential (the energy of position and/or configuration). Kinetic energy is the energy an object has because of its motion. Potential energy is the energy an object has because of its position.
The electron is accelerating by being repelled by a negative plate and attracted by a positive plate. After, the electron is being accelerated in the y-axis (deflected) by a positive and a negative deflective plate. Afterward, the electron keeps his elliptical/circle path because of a magnetic field (out of the page) created by a Helmholtz coil. -Proof that: em=2VB2r2 F=ma It is well known that a particle following a circular orbit must have an acceleration
Planck's constant: the constant relating the change in energy for a system to the frequency of the electromagnatic radiation absorbed or emitted, equal to 6.626 X 10^-34 J 5. Quantization: the concept that energy can occur only in discrete units called quanta 6. Photon: a quantum of electromagnetic radiation 7. Photoelectric effect: ejection of electrons from a substance by incident electromagnetic radiation, especially by visible light 8. E=mc^2: Einstein's equation proposing that energy has mass; E is energy, m is mass, and c is the speed of light 9.
