**Movement of gyroscope** is an example of three dimensional motion. Motion in space incorporates all the X, Y and Z axes. Motion of birds flying in the sky is also an example of three dimensional motion.

**When a body moves along a straight line path**, its motion is said to be one dimensional motion. It is also called motion in a straight line or rectilinear motion. For example, the motion of a train on a straight track, a stone falling down vertically.

Such objects are called projectiles and their path is called a trajectory. **The motion of falling objects as discussed in Motion Along a Straight Line is a simple one-dimensional type of projectile motion** in which there is no horizontal movement.

The motion of a body is said to be in one dimension or one –dimensional motion **if it moves along a straight line in any direction**. This type of motion is also called rectilinear or linear motion.

A One-Dimensional Array is **the simplest form of an Array in which the elements are stored linearly and can be accessed individually by specifying the index value of each element stored in the array**.

**Displacement, velocity, and acceleration** of objects moving in one dimension.

One dimensional motion is **motion along a straight line**. Here is an animated diagram showing an object moving along with a constant positive velocity.

Solution. A body is said to be in motion **when it change its position with respect to its surrounding objects with time**.

Remember that the study of one-dimensional motion is the study of movement in one direction, like a car moving from point “A” to point “B.” **Two-dimensional motion** is the study of movement in two directions, including the study of motion along a curved path, such as projectile and circular motion.

What is Motion in a Straight Line? If an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. Motion in a straight line is nothing but **linear motion**.

Two-dimensional (2D) motion means **motion that takes place in two different directions (or coordinates) at the same time**. The simplest motion would be an object moving linearly in one dimension. An example of linear movement would be a car moving along a straight road or a ball thrown straight up from the ground.

**Movement of gyroscope** is an example of three dimensional motion. Motion in space incorporates all the X, Y and Z axes. Motion of birds flying in the sky is also an example of three dimensional motion.

One Dimension: **Once you connect two points, you get a one-dimensional object: a line segment**. A line segment has one dimension: length. Two Dimensions: A flat plane or shape is two-dimensional.

MOTION IN ONE DIMENSION IS **MOTION ALONG A STRAIGHT LINE LIKE THAT OF A CAR ON A STRAIGHT ROAD**. THIS DRIVER ENCOUNTERS STOPLIGHTS AND DIFFERENT SPEED LIMITS ON HER COMMUTE ALONG A STRAIGHT HIGHWAY TO SCHOOL.

law of inertia, also called **Newton's first law**, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Linear motion

Examples Of Motion

involve motion. There is a change of position of the object involved in these activities. **The flow of air in and out of our lungs** is also an example of motion. The automobiles that carry passengers from the place of pick up to the destination possess motion.

Motion under gravity refers to **the movement of an object whose vertical motion is affected by the presence of gravity**. The force that attracts objects downwards is GRAVITY. In fact, gravity works towards the centre of the Earth.

**Rotatory motion**, rotatory motion, oscillatory motion, uniform circular and periodic motion, rectilinear motion, oscillatory motion and periodic motion.

**Motion of train on straight track** is a one dimensional motion whereas everything else is a two dimensional or three dimensional activity.
