Concept explainers

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, fo…

Chapter 2, Problem 12Q

Students have asked these similar questions

Does the initial velocity of an object have anything to do with its acceleration? For example, compared to dropping an object, if you throw it downward would the acceleration be different after you released it?

With respect to the motion of a car, describe a situation in which the car has zero speed but has a definite acceleration.

If you drop an object, its acceleration toward the ground is 10 m/s. If you throw it down instead, would its acceleration after throwing be greater than 10 m/s? Why or why not?
