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.

Understanding these concepts will help you grasp the principles of motion and its different aspects.

PHYSICAL SCIENCE

Motion and Stability: Forces and Interactions

Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets).

Apply scientific ideas about magnets to solve a problem through an engineering design project (e.g., constructing a latch to keep a door shut, creating a device to keep two moving objects from touching each other such as a maglev system).
