Velocity

The speed of an object in a specific direction, measured in meters per second (m/s).

Acceleration

The rate of change of velocity over time, measured in meters per second squared (m/s²).

Displacement

The change in position of an object, measured as a straight line from the initial to the final position, with direction (meters).

Initial Velocity (v₀)

The velocity of an object at the start of a time interval, measured in meters per second (m/s).

Final Velocity (v)

The velocity of an object at the end of a time interval, measured in meters per second (m/s).

Time (t)

The duration over which motion occurs, measured in seconds (s).

Rate of change of velocity

Refers to acceleration, indicating how quickly an object's speed is increasing or decreasing.

Distance traveled

The total length of the path an object has covered during its motion.

Time elapsed

The duration over which motion occurs, measured in seconds.

speed

Speed is defined as the distance traveled per unit of time. It is a scalar quantity, meaning it has magnitude but no direction. The formula for speed is:

[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} ]

Common units of speed include meters per second (m/s) and kilometers per hour (km/h).

distance

It is a scalar quantity that represents how far apart objects are from each other, regardless of direction. It can be calculated using various formulas depending on the context, such as in geometry or physics.

Definition of Scalar:

A scalar is a quantity that is fully described by a magnitude alone and does not have a direction. In mathematics and physics, scalars are often contrasted with vectors, which have both magnitude and direction. Examples of scalars include temperature, mass, and speed.

direction

Definition: The course along which someone or something moves; guidance or supervision in achieving a goal or outcome. Can also refer to the management of a project or organization, indicating the path to follow for success.

average speed

Definition: The total distance traveled divided by the total time taken for the journey. It represents how fast an object is moving on average over a specific time period. This measurement does not account for variations in speed throughout the journey.
