10.1 Introduction to Free Fall Motion Free fall is a type of motion experienced by objects that are falling under the influence of gravity. It occurs when an object is dropped from a height or is projected upwards and then falls back to the ground due to the force of gravity. 10.1.1 Definition of Free…

6.1 Introduction to Constant Acceleration Motion Constant acceleration is an important concept in physics that describes the motion of an object that experiences a steady (unchanging) increase or decrease in velocity over time. This type of motion is also known as uniformly accelerated motion, as the object’s velocity changes by a constant amount during each…

5.1 Introduction to Constant Velocity Motion Constant velocity is a term used to describe a situation where an object moves at a constant speed in a straight line. In other words, the velocity of the object remains unchanged, which means that its speed and direction do not change over time. In future chapters we will…

4.1 Position and Displacement Position is a fundamental concept in physics that describes an object’s location in space relative to a reference point. To understand position, we need to define a few key terms. The first is distance, which is the total length of the path an object travels. This can be a bit tricky,…

2.1 Introduction Vectors are a fundamental concept in physics which describe quantities that have both magnitude and direction. This definition cannot be stressed enough. Unlike scalars, which only have magnitude (such as temperature, mass, or time), vectors allow us to describe physical quantities that have both a size and an associated direction, such as velocity,…

1.1 Introduction Physics calculations often involve measurements of various physical quantities such as length, time, mass, and temperature. To make these calculations easier and more accurate, scientists have developed a system of units known as the metric system. This system has become widely used around the world and has many benefits over other systems of…
