Automotive Science

• The scientific method is a series of steps used to solve problems and eliminate errors.
• It is the foundation of automotive diagnosis and involves observing, formulating explanations, testing, and verifying.
• The "five whys" method is often used to find the root cause of a problem.
• Energy in the form of chemical, mechanical, and electrical energy is involved in the operation of an automobile.
• Torque is a rotating force measured in pound-feet or Newton-meters.
• Work is accomplished when force is applied to an object and it moves a certain distance.
• Power is the rate of doing work and is expressed in foot-pounds per minute.
• Horsepower is the power produced by an engine and is measured with a dynamometer.
• Sir Isaac Newton's three laws of motion explain the behavior of objects in motion.
• Kinetic energy is the energy of mass in motion and is determined by an object's mass and speed.
• Kinetic energy increases proportionally as weight increases.
• Kinetic energy increases as the square of its speed.
• If the weight of a moving object doubles, its kinetic energy also doubles.
• If the speed of a moving object doubles, the kinetic energy becomes four times as great.
• Inertia is the resistance to being put in motion and the tendency to remain in motion.
• The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity.
• A vehicle traveling at twice the speed has exactly four times as much kinetic energy.
• The relationships between weight, speed, and kinetic energy have significant practical consequences for the brake system engineer.
• If vehicle A weighs twice as much as vehicle B, it needs a brake system that is twice as powerful.
• The energy required to slow or stop a vehicle must be absorbed by the braking system.
