Motion

Motion is the act of changing place or position. Objects are in motion if they are changing position relative to a reference point. Motion can be described in terms of distance, time, speed, and direction.

Types of Motion

There are different types of motion, including:

Linear Motion: Motion along a straight line.
Circular Motion: Motion in a circular path.
Periodic Motion: Motion that repeats at regular intervals.

Study Guide

Here are some key points to understand about motion:

Distance: The total length of the path traveled by an object. It is a scalar quantity, meaning it only has magnitude.
Displacement: The change in position of an object in a particular direction. It is a vector quantity, meaning it has both magnitude and direction.
Speed: The rate at which an object covers distance. It is calculated as the distance traveled divided by the time taken.
Velocity: The rate at which an object changes its position. It is a vector quantity and is calculated as the displacement divided by the time taken.
Acceleration: The rate at which the velocity of an object changes over time. It is calculated as the change in velocity divided by the time taken.
Graphs of Motion: Motion can be represented on graphs, such as distance-time graphs and velocity-time graphs.
