Question

For an object in non-uniform motion ___.

• A. speed is zero
• B. speed changes with time
• C. speed is constant
• D. object covers equal distance in equal interval of time

Answer 1

The correct option is B speed changes with time

When an object covers unequal distance in equal time interval, it is said to be in non-uniform motion.
In non-uniform motion, object changes its speed with the time. If speed remains constant, then the object is said to be in uniform motion.
