EVOC written test Questions and Answers With Absolute Solution

EVOC written test Questions and Answers With Absolute Solution 90-95%. Leave room for mechanical and human error - On the road, you should never drive over what percent of your ability? relaxed - A ________ driver is the best driver on the road Technique over speed - What is better, speed or technique? The study of vehicles in motion. - What are vehicle dynamics? First Law. Every body at rest tends to remain at rest, while every body in motion tends to remain in motion in a straight line until acted upon by unbalance external force. This is also known as inertia or centrifugal force. - What is the 1st law of Newtonian Law? The acceleration of a body is proportional to the froce applied and inversely proportional to the mass of the body. This is the law of acceleration. The force exerted on an object is equal to its mass times acceleration. F = ma. - What is the 2nd law of Newtonian Law? Intertia or centrifugal force - What is the 1st Newtonian Law also known as? The law of acceleration - What is the 2nd Newtonian Law also known as? For every action force there is an equal and opposite reaction force. This is the law of the conservation of energy: Momentum. - What is the 3rd Newtonian Law? Momentum - What is the 3rd Newtonian law also known as? Force - What word is used in each of Newton's Laws of Motion? Energy that causes or alters motion - What is force? Centrifugal force, centripetal force, inertia, momentum, velocity, gravity, friction. - What are the types of force? As a vehicle travels around a corner, there is an increase in centrifugal force which IMPELS AN OBJECT OUTWARD FROM THE CENTER OF ROTATION. - What is centrifugal force? (first newtonian law) The OPPOSITE of centrifugal force, pushing the object toward the center. Characterized by the vehicle's ability to maintain its intended path while cornering. - What is centripetal force? RESISTANCE to motion, action, or change. - What is intertia? (First newtonian law) The greater the speed or mass, the more time and distance needed to effect a stop. - What is momentum? (Third newtonian law) The rate of change of position relative to time. Speed of motion in a particular direction. Velocity is a vector quality, having both magnitude and direction. Velocity forumula: V = S x 1.47. - What is velocity? F = ma (Force = mass x acceleration) - What is the forumla for acceleration/force? V = S x 1.47 (Velocity = speed x 1.47) - What is the forumla for velocity? The constant pull of the earth. g = 32.2fps(squared) - What is gravity? G = 32.2fps(squared) - What is the formula for gravity? The force between two bodies that resists motion. 1.) Sliding friction - tires locked and sliding on the road surface 2.) Rolling friction - Vehicle starting from a stop or turning 3.) Static Friction - A vehicle stopped. - What is friction? Sliding friction, rolling friction, static friction. - What are the 3 types of friction? POTENTIAL ENERGY - the energy stored in the springs of the suspension of a system of a skidding vehicle, when released, causes a counter-skid. KINETIC ENERGY - The motion of energy that is changed STATIC ENERGY - The energy that holds the vehicle to the pavement and resists initial movement of the vehicle. - Energy Potential energy, kinetic energy, static energy - What are the 3 types of energy? When at rest or when moving in a straight line at a constant speed on a paved, level surface. - When is a vehicle most stable? True - Weight is contained within the vehicle and does NOT change much (True or false) True - Weight transfer disrupts vehicle stability. (True or false) Acceleration, braking, steering - What 3 driver inputs cause weight transfer in a vehicle to cause a disruption in stability? Acceleration - referred to as "acceleration squat" - weight transfer is demonstrated by Weight lifts up from front end of vehicle and transfers to the rear upon acceleration. - What happens during an acceleration squat? The weight of your vehicle transfers to the front and away from the back, causing the front of the vehicle to front end to go lower and rear end to go higher up. - What happens during a break dive? weight will transfer to the right (passenger's side) - When steering, which direction will your vehicle "roll" if you are turning left?
