Figure 1 shows a worker using an electric grindstone propelled by a motor. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. The design of all kinds of vehicles, be they submarines, boats and all those that move on water. If the . At the quantum level of particles, energy and matter can basically swap between states. Know Everything about Brakes in this Automobile Quiz. Calculate rotational kinetic energy. Coupe Two door car that holds 2 or 4 people, usually use for sports cars. The body changes its path so there is a change in direction (velocity) but its speed remains . 33. The kind of motion may be translation (or motion along a . Fluorescent: Light is produced by a chemical reaction. Heavier moving things have more energy than lighter moving things. The amount of kinetic energy that it possesses depends on how much mass is moving and how fast the mass is moving. 3. Answer Answer: (c) Q.12. When something is in motion, it has kinetic energy. The energy of a moving object is called kinetic energy. If an object is moving, then it possesses kinetic energy. kinetic energy, form of energy that an object or a particle has by reason of its motion. -Physics is the study of energy, forces and motion. The kinetic energy of an object is the energy it has because of its motion. Kinetic energy is the energy an object has because of its motion. If you move the car up a mountain, it has kinetic and potential energy. According to State of Motion. The equation is KE = 0.5*m*v^2. These will come from the seat, the seat belt, airbags or other parts of the vehicle such as the steering column. Energy can be defined as the capacity for doing work. Newton's Second Law of Motion (Force) The acceleration of an object depends on the mass of the object and the amount of force applied.
