2. You decide to enjoy the lovely Santa Barbara weather by taking a ride in your car along the coast. (a) Driving on 101, you pass by an accident. How far does your car travel forward during the 1 second that you take to look at the accident on the side of the road, if you're going with 100 km/h? (b) Then, you drive up a hill at a constant speed of 40 km/h and return down the hill at a speed of 60 km/h. What is the average speed for the round trip?
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.
