2. You are standing on the centre point (0,0,0) of a football pitch which you have marked out in a grid with horizontal and vertical lines every metre. A ball travels from one goal to the other at a constant speed of 10ms ¹. At time t=0 it passes you. (i) Where will the ball be at t=2s? (ii) What speed will it be travelling at at t=2s? Suppose the match is being watched by somebody moving in a bus, travelling in the opposite direction to the ball at 10ms¹ and they pass by you at the same moment as the ball. Use the Gallilean transformations to figure out: (i) where the ball is in their frame when the time (in their frame) is t=0s (ii) where the ball is in their frame when the time (in their frame) is t=2s (iii) the speed of the ball in their frame when the time (in their frame) is t=2s Now suppose that the bus is travelling in the same direction as the ball. Use the Gallilean transformations to figure out:

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.
