What is a Frame of reference?

A coordinate system or a set of objects used to specify the position and motion of an object.

Define Instantaneous velocity.

The velocity of an object at a specific moment in time (t). It is the limit of the average velocity as the time interval approaches zero (\Delta t \to 0).

What is Kinematics?

The branch of classical mechanics that describes the motion of points, bodies, and systems of bodies without considering the forces that cause the motion.

What does Magnitude refer to?

The size or extent of a physical quantity, often referring to the length or absolute value of a vector quantity.

Explain what a Scalar is.

A physical quantity that is completely described by its magnitude only. Examples include mass, time, temperature, and speed.

What is Speed?

The rate at which an object covers distance. It is a scalar quantity representing the magnitude of velocity.

Define Vector.

A physical quantity that has both magnitude and direction. Examples include displacement, velocity, acceleration, and force.

What is Velocity?

The rate at which an object changes its position. It is a vector quantity that includes both speed and direction.

What is a Resultant Vector?

The single vector that represents the sum of two or more vectors. It describes the net effect of all the individual vectors.
