FORCE, MOTION & NEWTON'S LAWS
This is a push or pull that can change the motion of an object.
What is Force?
This is the turning force produced around a point or axis.
What is torque?
This is the ability to do work.
What is energy?
This principle states that pressure applied to a confined fluid is transmitted equally in all directions.
What is Pascal's Law?
This force resists motion between two surfaces that are in contact.
What is friction?
Newton's Law states that for every action there is an equal and __________ reaction
What is oposite?
A longer wrench makes it easier to turn a fastener because it increases this.
What is leverage?
Thermal energy naturally transfers from an object with a higher temperature to one with a lower temperature. This transfer is called this.
What is heat?
A hydraulic system has a 1-square-inch input piston and a 4-square-inch output piston. If 50 lb of force is applied to the input piston, how much theoretical force is produced at the output piston?
What is 200 lb?
Tire traction depends heavily on the friction between the tire and this surface.
What is the road?
According to Newton's Second Law, increasing the force applied to an object while keeping its mass constant will cause its acceleration to do this.
What is increase?
A technician applies 50 lb of force to a wrench with a 2-ft handle. How much torque is produced?
What is 100 lb-ft?
Gasoline contains this type of energy before combustion converts it into other forms of energy.
What is chemical energy?
If pressure is reduced below atmospheric pressure in a system, the system is said to have this condition.
What is a vacuum?
A rotating component that is out of balance can produce this unwanted movement that may be felt by the driver.
What is vibration?
A technician applies 40 lb of force to a wrench that is 1.5 ft long. Using Torque = Force × Distance, how much torque is produced?
What is 60 lb-ft?
An engine produces 200 lb-ft of torque at 5,000 RPM. Using HP = Torque × RPM ÷ 5,252, approximately how much horsepower does it produce?
What is approximately 190 horsepower?
When the chemical energy in gasoline is converted into heat and then mechanical energy in an engine, this process is occurring.
What is energy conversion?
A hydraulic system has an input piston area of 2 in² and an output piston area of 10 in². If 30 lb of force is applied to the input piston, how much force should theoretically be produced at the output piston?
What is 150 lb?
When two or more elements chemically combine to create a new substance, this occurs.
What is a chemical reaction?
Newton's First Law states that an object will remain at rest or continue moving unless acted upon by this.
What is an outside force
A gear with 10 teeth drives a gear with 40 teeth. What is the gear ratio?
What is 4:1?
A technician observes that a metal brake rotor becomes hotter during repeated braking. The increase in temperature is primarily caused by the conversion of mechanical energy into this form of energy.
What is thermal energy?
A technician finds that a hydraulic brake system has trapped air. Because air is compressible while brake fluid is essentially incompressible, the brake pedal will likely feel this way.
What is soft or spongy?
When electric current produces a magnetic field, this relationship between electricity and magnetism is demonstrated.
What is electromagnetism?
