 # What Is Required To Cause Acceleration?

## What is a 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..

## What causes poor acceleration?

There are many reasons why your vehicle may be losing power, especially when accelerating. Some of these common causes are: Mechanical problems such as: Low compression, clogged fuel filter, dirty air filter, clogged Exhaust Manifold. … Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.

## How does force affect acceleration?

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

## Do heavier objects fall faster?

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance.

## Why does mass not affect acceleration?

“What are the factors that affect the acceleration due to gravity?” Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.

## In which situation the box will accelerate more?

the object with greater mass will experience a smaller acceleration and the object with less mass will experience a greater acceleration.

## Which of the following will cause an acceleration in an object?

To cause acceleration in an object the necessary factor is unbalanced .

## What is the force that moves a car?

frictional forceFriction is a force that arises when things rub together. The frictional force between the road and tire is what allows the tire to “push” off the road, thus moving the car forward (Newton’s third law — the action is the pushing frictional force, the reaction is the forward movement of the car).

## What three things can cause acceleration?

What three things can cause acceleration? Acceleration is the rate at which velocity changes. An increase in speed, a decrease in speed, and a change in direction can cause acceleration.

## Why does the car in picture B accelerate?

It is accelerating because the direction of the velocity vector is changing.

## What is the difference between velocity and acceleration?

Instantaneous velocity refers to an object’s velocity in an exact moment in time. Acceleration is the change in the velocity of an object, either as it increases or decreases. Acceleration is also a vector and will have both a value and a direction.

## What two things affect acceleration?

The acceleration of an object depends on the mass of the object and the amount of the force applied to it. It states that the acceleration of an object increases with increased force and decreases with increased mass.

## Does constant speed mean no acceleration?

First, constant speed does not mean zero acceleration. An object could be going on a curved path at constant speed. The object has an acceleration. Zero acceleration means constant velocity.

## How Can acceleration be calculated?

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

## What force is directly responsible for making the car accelerate?

friction forceAnswer. Explanation: The friction force is what actually moves the car. There are other factors and forces which must act to make the car move, but ultimately, the single force responsible for the movement is this friction force.
