Statement
difficulty
Determine if the following statements are true or false:
a) The circular motion is a rectilinear motion.
b) Non-rectilinear motions can be described by means of rectilinear motions.
c) A soccer head-butt can be studied as the composition of a u.r.m. and a u.a.r.m.
Solution
a) False
A circular motion describes a trajectory in the shape of a circle, not a straight line.
b) True
Motion in which the trajectory is not a straight line, may be composed from straight line motions.
c) True
On the x-axis, the motion would be a u.r.m. and in the y-axis, a u.a.r.m.
