Answer 1

A) Uniform accelerated motion.

______________________________

Explanation :-

Uniform acceleration :-

A body has a uniform acceleration if it travels in a straight line with and its velocity increases by equal amounts in equal intervals of time.

Here are some examples of the uniformly accelerated motion :-

• The motion of a freely falling body is an example of uniformly accelerated motion.
• The motion of a ball rolling down an inclined plane is an example of uniformly accelerated motion.

Non - Uniform Acceleration :-

A body has a non - uniform acceleration if its velocity increases by unequal amounts in equal intervals of time.

Here are some examples of the non - uniform acceleration :-

• The speed (velocity) of a car running on a crowded city road changes continuously. At one moment the velocity of the car increases whereas at another moment it decreases.So,the movement of a car on a crowded city road is an example of non-uniform acceleration.
