acceleration
The speed of something in a given direction.
The ratio you are referring to is called speed or velocity. Speed is the total distance traveled divided by the time it took to travel that distance. Velocity includes direction and is a vector quantity, while speed is a scalar quantity.
The ratio of the total displacement of an object to the total time taken is called the average velocity. It gives an overall measure of how fast the object is moving in a given direction over a certain period of time.
Velocity is distance over time
Speed and velocity both involve the rate of motion, with velocity additionally considering direction. Acceleration involves changes in velocity over time, indicating how quickly an object is speeding up or slowing down. Speed and velocity relate to the rate of motion, while acceleration represents changes in velocity over time.
The ratio of (distance) / (time), called "speed".The ratio of (speed) / (time), called "acceleration".The ratio of (force) / (area), called "pressure".The ratio of (force) / (acceleration), called "mass".The ratio of (mass) / (volume), called "density".The ratio of (distance) / (volume), sometimes called "fuel economy".The ratio of ( 1 ) / (time), called "frequency".The ratio of (energy) / (time), called "power".
Average velocity is defined as the change in position of an object divided by the time taken to undergo that change. It gives a measure of how fast an object is moving in a particular direction over a given time interval. Mathematically, it is represented as: average velocity = (final position - initial position) / time.
Acceleration is any change in velocity during a length of time.
The ratio of change in position to the time interval is known as velocity. Velocity is a vector quantity that describes how fast an object's position changes and in what direction. It is calculated by dividing the change in position by the time interval.
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
An increase in the magnitude of velocity is called acceleration. It refers to the rate at which an object's velocity changes over time.
The rate at which velocity changes with time is called acceleration. It can be defined as the change in velocity over a specific period of time. Positive acceleration indicates an increase in velocity, negative acceleration (or deceleration) indicates a decrease in velocity, and zero acceleration indicates a constant velocity.
