Learner's Activity 2 – Speed and distance time graph 1) Distance 300 200 10 20 30 Time The above distance-time graph shows the distance moved by a car over a period of time. a) What is the speed of the car in the first 10 seconds? b) What is the car doing from 10 to 20 seconds? c) What is the speed of the car from 20 to 30secs? Will you be able to tell without calculations if it is travelling faster or slower compared to speed in the first 20 seconds? d) What is the total distance travelled by the car? e) Given the average speed of the car for the whole journey is 12m/s, calculate the value of t. f) What is the car doing in the last few seconds?
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.
