a bird flying in the air

a leaf falling from a tr

a train traveling along a track

D)

a lady bug crawling on a soccer ball

Answer 1

An example of two-dimensional motion is a leaf falling from a tree, as it exhibits movement in both horizontal and vertical directions simultaneously. Projectile motion is an illustration of this, where horizontal and vertical motions combine to form a curved trajectory.

Step-by-step explanation:

An example of two-dimensional motion is a leaf falling from a tree. This is because the leaf can move in multiple directions as it falls, namely horizontally due to the wind and vertically due to gravity. In physics, two-dimensional motion is characterized by movement that occurs in two different axis directions simultaneously.

Another key concept in physics is the trajectory of an object in motion. In two dimensions, a trajectory can be caused by independent perpendicular motions, such as when a baseball is hit and travels through the air. The motion of the ball can be broken down into horizontal movement from the force of the bat, and vertical movement from gravity pulling it back towards the ground.

When analyzing projectile motion, it is essential to resolve the movement into these perpendicular components. This simplifies the complex path of a moving object into two one-dimensional motions which can be studied independently.

Answer 2

A leaf is falling from the tree.

Step-by-step explanation:

If motion is in only one direction(x-direction) then it is know as one directional motion.

If motion is in only two direction (x and y directions) then it is know as two directional motion.

If motion is in only three direction (x , y and z directions) then it is know as three directional motion.

A bird is flying in the air -This is three directional motion.

A leaf is falling from the tree - This is two directional motion.

A train is running on track - This is one directional motion

A lady is crawling on the surface of the ball - This is three directional motion.

Therefore the answer is ---

A leaf is falling from the tree.
