Question

The if the speed on an object is variable, it is not in.

1.Non Accelerated motion
2.uniform motion
3.Accelerated motion
4.non uniform motion​

Answer 1

Uniform motion is the answer.

Answer 2

If the speed of an object is variable, then it is not in Non-Accelerated motion and uniform motion.

Explanation:

• Velocity is the magnitude of speed and its direction at any instance.
• So, if speed is variable then velocity is also variable.
• Acceleration is the rate of change of velocity.
• Therefore, when speed is variable, the object is in accelerated motion.

• When an object is traveling with the varied speed it covers the unequal distance in an equal interval of time, which means an object is in non-uniform motion.
• For uniform motion speed must be constant.
• Therefore, when speed is variable, the object is in non-uniform motion.
