6. If one object has a greater speed than a second ob- ject, does the first necessarily have a greater acceler- ation? Explain, using examples. 7. Compare the acceleration of a motorcycle that accel- erates from 80 km/h to 90 km/h with the accelera- tion of a bicycle that accelerates from rest to 10 km/h in the same time. 3. How is speed represented on a speedometer? How is acceleration represented? 9. Can an object have a northward velocity and a southward acceleration? Explain.
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.
