Motion at a constant speed.
Scalars and Vectors: Scalars are quantities that have only magnitude, while vectors have both magnitude and direction. In kinematics, displacement, velocity, and acceleration are all vectors.
Position: The location of an object at any given time.
Displacement: The change in position of an object over time.
Speed: The rate at which an object covers distance. It is a scalar quantity.
Velocity: The rate of change of displacement. It is a vector quantity.
Acceleration: The rate of change of velocity. It is a vector quantity.
Uniform Motion: Motion with a constant velocity is called uniform motion. In uniform motion, the acceleration is zero.
Non-Uniform Motion: Motion with varying velocity is called non-uniform motion. In non-uniform motion, the acceleration is non-zero.
Average Speed: The average speed is calculated as the total distance covered divided by the total time taken. It is a scalar quantity.
Average Velocity: The average velocity is calculated as the total displacement divided by the total time taken. It is a vector quantity.
Instantaneous Speed: The speed of an object at a particular instant in time.
Instantaneous Velocity: The velocity of an object at a particular instant in time.
Graphical Representation of Uniform Motion: Diagrams, graphs, and charts may be used to represent uniform motion.
Equations of Uniform Motion: Equations used to describe uniform motion include distance-time, displacement-time, and velocity-time.
Free Fall: The acceleration due to gravity causes free fall. In free fall, an object falls under the influence of gravity alone.
Projectile Motion: The motion of an object projected into the air and then falling under the influence of gravity. The projectile's motion is influenced by its horizontal and vertical velocity components.
Linear Uniform Motion: The motion of an object following a straight line path at a constant speed is called linear uniform motion.
Circular Uniform Motion: When an object moves in a circular path at a constant speed, it is called circular uniform motion.
Projectile Motion: This is a type of motion in which an object is thrown or projected into the air and moves along a parabolic path. It is caused by the force of gravity.
Curvilinear Uniform Motion: When an object follows a curved path at a constant speed, it is said to be in curvilinear uniform motion.
Oscillatory Motion: This type of motion is characterized by the back-and-forth movement of an object around a central point. A simple example is the motion of a pendulum.
Harmonic Motion: When an object moves back and forth with a constant period and amplitude, it is called harmonic motion.
Simple Harmonic Motion: The motion of an object undergoing harmonic motion with a sinusoidal motion is known as simple harmonic motion.
Angular Uniform Motion: This is a type of motion in which an object moves in a circular path at a constant angle speed.
Rectilinear Uniform Motion: This type of motion occurs when an object moves along a straight path at a constant speed.
Translational Motion: When an object moves from one place to another along a particular direction and continues to move in that direction, it is said to be undergoing translational motion.
Rotational Motion: This is a type of motion in which an object rotates around an axis. The axis can be external or internal.
Rolling Motion: This type of motion happens when an object moves forward and rotates at the same time.
Periodic Motion: When an object repeats a motion in a given time at a particular frequency, it is said to be undergoing periodic motion.
Non-Uniform Motion: This type of motion happens when an object does not move at a constant speed, i.e., its velocity changes as time passes.
Relative Motion: When an observer perceives motion in relation to a stationary object, it's called relative motion.
