You rode a roller coaster with a loop 100 meters in height. What is the acceleration due to gravity at the top of the loop? b. A ball was thrown upward. What is the velocity of the ball at the highest point of travel? c. A ball was thrown upward with an initial velocity of 10 m/s. What is the velocity of the ball once it goes back to the owner's hand? Assume air resistance is negligible. d. An object is moving to the right with a constant acceleration pointing to the left. The velocity of the object increases. True or False? e. When you drop any object, it is always exhibiting a free fall motion. True or False
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.
