After spending the afternoon studying together, your friend leaves to walk home. Three minutes after your friend leaves, you notice that their house key was left on the table. You decide to try to catch your friend before they reach their house. The values you enter in this part will be used to make later calculations. Choose reasonable rates for you and your friend. Recall that distance traveled is equal to the product of the rate of travel and the time:  d = rt. Use this formula to write expressions to show the distance you and your friend will have traveled. Let t represent the amount time in hours you will need in order to catch up to your friend. Remember that your friend left before you, so you will use 3 extra minutes, or  t + 0.05 hours,  to calculate their distance.   Your Friend what is the rate in mph; (t + 0.05) = Time (in hours);(          )(t + 0.05) = distance (in miles) Me what is my rate in mph; t = Time (in hours); (      )t = distance (in miles)

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.
