Uniform motion refers to motion without a net external force or acceleration.
Uniform motion is contained in Newton's first law. Acceleration is defined in Newton's second law.
Motion at constant speed in a straight line is the definition of uniform motion.
An object in uniform motion covers equal distances in equal time intervals.
Which of the following is an example of uniform motion?
a. A person at rest starts running in a straight line in a fixed direction
b. A car going around a circular track at a constant speed
c. A ball dropped from the top of a building
d. A hockey puck sliding in a straight line at a constant speed
