pose a car travels speed of 30.0 m/s, and uses 2.20 gallons of gasoline. Only 309% G the gasoiine goes into userul vwork by that keeps car moving at const speed energy content of gasoline 1.30 x 108 ) per gallon.) (a) What.is.the.forçe (in N) exerted to keep the car moving at constant speed? (Enter a number.) x N Enter a number. (b) If the required force is directly proportional to speed, how many gallons will be used to drive 108 km at a speed of 28.0 m/s? (Enter a number.) gallons
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
