A commuter backs her car out of her garage with a constant acceleration of 1.3 m/s2. Assume that her initial motion is in the positive direction. How long does it take her to reach a speed of 2.45 m/s in seconds? t1 = If she then brakes to a stop in 0.85 s, what is her acceleration in meters per square second? a2 =
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.
