Answer 1

If a ball is released from the terrace of a building, it comes down in non-uniform linear motion. On the other hand, it reaches the ground in non-linear motion if it is thrown with force away from the terrace in a direction parallel to the terrace.

Explanation:

If a ball is released from the terrace of a building, it falls straight down due to gravity and experiences non-uniform linear motion. This is because gravity causes its speed to increase continuously as it falls, making the motion non-uniform, and since it moves in a straight vertical line, the motion is linear.

On the other hand, if the ball is thrown with force away from the terrace in a direction parallel to the terrace, it follows a non-linear motion. This happens because the ball combines two motions: horizontal motion (from the force of the throw) and vertical motion (due to gravity). Together, these create a curved, parabolic path, which is classified as non-linear motion.
