What is straight line motion?

Physics motion in a straight line: Motion in physics: movement is a phenomenon in which an object over time changes position. In terms of movement, distance, speed, acceleration along with time, motion is described quantitatively. In the field of physics that describes the motion of objects but does not refer to the source of objects is called kinematics.

Motion In A Straight Line - Definition, Formulas, Examples, FAQs

Motion:

Motion is defined as the movement of any object from one position to another with respect to the observer as time passes.

Motion along a straight line:

When an object's location in relation to its surroundings varies over time, it is said to be in motion. It is a change in an object's location over time. Motion in a straight line is defined as movement in a straight path.

Motion in a straight line formulas

Three rules of classical mechanics were formulated by Newton along with Euler historically:

Three motions in straight line formulas are as follows:

v=u+at
s=ut+0.5at²
v²=u²+2as

Define linear motion

Linear motion is the motion that is natural to an object: moving in a straight line. According to Newton's First Law of Motion, an object not affected by any force will continue indefinitely in a straight line. The position x, which varies with t, can be used to explain the motion of a particle (a point-like object) down a line (time). An athlete running 100 metres on a straight track is an example of linear motion. Motion along a straight line is called linear motion.

Linear Motion Definition: The object goes from one point to another along a straight line or a curved route in linear motion.

Examples of linear motion or Straight line motion examples:

Linear motion is a one-dimensional motion along a straight line. When an object travels in a straight line, its position changes with the passage of time. A stone falling from a set height, an athlete running 200 metres on a straight track, a train travelling on a straight track, along with an automobile going at a consistent speed are all linear motion examples of linear motion.

NCERT Physics Notes:

Motion in one Dimension Class 11

When only one of the three coordinates indicating the object's position varies with time, the motion is said to be a one-dimensional motion. One-dimensional motions include the motion in 1 dimension of a car on a road, the motion of a train along a railway track etc.

Rectilinear motion is another name for one-dimensional motion. When two of the three coordinates describing an object's position change over time, the motion is said to be two dimensional. A planet is orbiting the sun, or a body travelling around the perimeter of a circle, are instances of two-dimensional motion. Motion in a plane is another name for two-dimensional motion.

Frequently Asked Questions (FAQs)

1. Give an example of linear motion.

2. What is the definition of motion in a straight line?

The movement of any object from one position to another position with respect to the observer is called Motion and when an object moves along a straight line, the motion of the object is called rectilinear motion.

3. In a straight line motion, what is positive and negative acceleration?

Positive acceleration occurs when an object's speed rises over time. Acceleration is measured in the direction of motion, and it is negative if the speed of an item decreases over time. The direction of motion is reversed with acceleration.

4. What do you mean by motion in one direction?

A particle is considered to be travelling in one dimension if it moves in only one direction throughout its journey.
