There were a lot of theories about the physical world as a mechanical system at this
time. Then, with the discovery of radioactivity weakened some of these ideas. This

2) What is uniform and
constant acceleration?
Acceleration is defined as the rate at
which an object changes its velocity.
Constant acceleration is changing by
the same amount each unit of time.
Which car is accelerating?
2) Why is acceleration a
vector?
(e) On the axes below, sketch graphs of the objects position x versus time t and kinetic energy K versus time t.
Assume that x = 0 at time t = O. The two graphs should cover the same time interval and use the same scale on the
