# Question

Consider the following combinations of signs and values for velocity and acceleration of a particle with respect to a one-dimensional x axis:

Velocity Acceleration

a. Positive Positive

b. Positive Negative

c. Positive Zero

d. Negative Positive

e. Negative Negative

f. Negative Zero

g. Zero Positive

h. Zero Negative

Describe what a particle is doing in each case, and give a real life example for an automobile on an east-west one-dimensional axis, with east considered the positive direction.

Velocity Acceleration

a. Positive Positive

Can the equations of kinematics (Eqs. 2.9–2.13) be used in a situation where the acceleration varies in time? Can they be used when the acceleration is zero?Atoms “strive toward stability” by trying to fill the outer energy-level shell to the maximum stable number of 8.
