# Relationship of velocity and acceleration

### How are acceleration, time and velocity related? | Socratic

Displacement, velocity, acceleration. Kinemetics is the description of motion; it concerns only the accurate description of the positions of objects, and the change . Useful equations related to acceleration, average velocity, final velocity and distance traveled. Velocity and acceleration are the two key concepts which are always discussed while studying motion. Velocity can be understood as the.

If you've been paying attention, then you should have anticipated the answer. It could be the velocity the meteor has as it passes by the moon, as it enters the Earth's atmosphere, or as it strikes the Earth's surface.

## Equations of Motion

It could also be the meteorite's velocity as it sits in the bottom of a crater. Are any of these the final velocity?

Someone could extract the meteorite from its hole in the ground and drive away with it. Probably not, but it depends.

### Difference Between Velocity and Acceleration (with Comparison Chart) - Key Differences

There's no rule for this kind of thing. You have to parse the text of a problem for physical quantities and then assign meaning to mathematical symbols. The last part of this equation at is the change in the velocity from the initial value. Recall that a is the rate of change of velocity and that t is the time after some initial event.

Rate times time is change. Move longer as in longer time.

Acceleration compounds this simple situation since velocity is now also directly proportional to time. Try saying this in words and it sounds ridiculous.

### What is the Difference Between Velocity And Acceleration? | Sciencing

Would that it were so simple. This example only works when initial velocity is zero. Displacement is proportional to the square of time when acceleration is constant and initial velocity is zero.

A true general statement would have to take into account any initial velocity and how the velocity was changing. It is a vector expression that has both magnitude and direction.

## How are acceleration, time and velocity related?

An object is said to be accelerated when there is an increase or decrease in its speed or change in the direction of motion or both.

When the direction of acceleration is parallel to velocity, then it is believed that object is accelerating or its speed is going up. However, when the direction of acceleration is anti-parallel to velocity, then the object is decelerating, or its speed is slowing down.

There can be two types of acceleration, which are: When the object travels at a uniform speed in a circular motion, like the revolution of the earth, then this acceleration is called centripetal acceleration because there is a change in the direction of the object. When there is no change in the direction of motion but the speed changes with time, is called tangential acceleration.

**Position, Velocity, Acceleration using Derivatives**

Key Differences Between Velocity and Acceleration The difference between velocity and acceleration can be drawn clearly on the following grounds: The velocity of an object refers to the speed in a specific direction. Acceleration implies any change in the velocity of the object with respect to time.

Velocity is nothing but the rate of change of displacement. On the other hand, acceleration is the rate of change of velocity with respect to time.
