A driver travelling at 7Okm/h tries to stop the car and finds that the brakes has failed. The emergency brake is then pulled and the car comes to a stop in 120m. 1. What was the final velocity of the car? a. 70km/h b. 120m/s c. Okm/h d. 1m/s 2. The velocity of the car was decreasing, so the acceleration was a. Zero b. negative c. positive d. increasing 3. To determine the acceleration of the car what would be the equation to be used?
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.
