The motion of a cart moving in a straight line is represented by the velocity-time graph shown below. Assume "forwards" is positive and "backwards" is negative. Which of the following statements about the motion of the cart is true? The motion of a cart moving in a straight line is represented by the velocity-time graph shown below. Assume "forwards" is positive and "backwards" is negative. Which of the following statements about the motion of the cart is true? A. The cart is moving forwards and speeds up until 3s and then the cart slows down B. The cart moves forwards with a fixed speed until 3s and then moves backwards with a fixed speed C. The cart moves backwards with a fixed speed until 3s and then forwards with a fixed speed D. The cart moves with a constant velocity pointing backwards the whole time E. The cart is moving backwards and slows down until 3s, comes to a stop, and after that it speeds up moving backwards F. The cart is moving forwards and slows down until 3s, comes to a stop, and after that it speeds up moving forwards
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.
