# Quick Answer: What Is Another Name For Acceleration?

Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity.

Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared..

## What is the another name of negative acceleration?

retardationNegative acceleration is also called retardation.

## What is the definition acceleration?

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

## What is another word for positive acceleration?

1. hastening, hurrying, stepping up (informal), expedition, speeding up, stimulation, advancement, promotion, spurring, quickening He has called for an acceleration of political reforms. 2.

## What is positive acceleration?

A positive acceleration means an increase in velocity with time. negative acceleration means the speed reduces with time. its a retardation. If the speed is increasing, the car has positive acceleration. When the car slows down, the speed decreases.

## Is a car slowing down accelerating?

A car that is slowing down is decreasing its speed. … In both cases, the car is accelerating, but one acceleration is positive and one is negative. When a car changes direction, it is also accelerating. In the figure to the right, compare the direction of the acceleration to the direction of the velocity.

## What is negative acceleration?

Negative Acceleration. Deceleration always refers to acceleration in the direction opposite to the direction of the velocity. Deceleration always reduces speed. Negative acceleration, however, is acceleration in the negative direction in the chosen coordinate system.

## What is the other name of acceleration?

The act or condition of increasing in speed or rate. hastening. quickening. stimulation. advancement.

## Does acceleration affect momentum?

Acceleration and Momentum An object that is accelerating, therefore, has an increasing velocity and increasing momentum. A decelerating object has a decreasing velocity and will lose momentum over time. An object in motion with zero acceleration will have a constant velocity and thus have a constant momentum.

## Is momentum a force Yes or no?

Momentum is the force that exists in a moving object. The momentum force of a moving object is calculated by multiplying its mass (weight) by its velocity (speed).

## Which is an example of negative acceleration?

Because the velocity/speed of this object is decreasing over time, this means there is a negative acceleration. A jet airliner starts at rest and moves down the runway in a straight line. After accelerating for 20 seconds, it reaches a speed of 80 meters per second.

## What is acceleration sentence?

an increase in rate of change 2. the act of accelerating; increasing the speed 3. … There has been a rapid acceleration in the growth of industry. 2. He has also called for an acceleration of political reforms.

## Is momentum and acceleration the same?

Acceleration is the rate of change of velocity. Momentum is the mass times the velocity. So if you multiply the mass times the acceleration, you get the rate of change of momentum.

## What is the opposite of acceleration?

the act of accelerating; increasing the speed. Antonyms: deceleration, retardation, slowing.

## What is SI unit of retardation?

Retardation means change in velocity per unit time is negative . e.g retardation is also a acceleration but negative sign . hence, si unit of retardation is equal to Si unit of acceleration . SI of retardation = m/s²
