Two stones are released from rest, at the same height above the ground, one after the other. Will the time interval between the instants at which they hit the ground be Choose one: a. Greater than the time interval between the instants of their release? b. Equal to the time interval between the instants of their release? c. Smaller than the time interval between the instants of their release? A golfer gives a golf ball a velocity of 48 m/s at an angle of 40° with the horizontal. What is the vertical component of the ball's initial velocity? Choose one: a. 31 m/s b. 48 m/s
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.
