Speed
A scalar quantity representing distance traveled over time, without direction.
Velocity
A vector quantity representing displacement over time, including both magnitude and direction.
Displacement
A vector quantity representing the shortest path between two points, with both magnitude and direction.
Vector
A quantity with both magnitude and direction, used to represent displacement and velocity.
Scalar
A quantity with only magnitude, such as speed or distance, without direction.
Magnitude
The size or length of a vector, representing the amount without direction.
Direction
The orientation of a vector in space, often specified by an angle.
Theta
The angle used to describe the direction of a vector in two-dimensional motion.
Components
The projections of a vector along the axes, typically labeled as x and y components.
VX
The x-component of a velocity vector, calculated using displacement or trigonometry.
VY
The y-component of a velocity vector, calculated using displacement or trigonometry.
Pythagorean Theorem
A mathematical equation used to calculate the hypotenuse of a right triangle.
Tangent Inverse
A trigonometric function used to calculate the angle of a vector from its components.
Hypotenuse
The longest side of a right triangle, opposite the right angle, representing the vector's magnitude.
Trigonometric Functions
Mathematical functions like sine and cosine used to calculate vector components.
