## What is the difference between velocity and acceleration?

The crucial difference between velocity and acceleration is that velocity is variation in position of the object in a particular direction in unit time.

On the contrary, acceleration is variation in velocity in a certain direction per unit time..

## Is motion possible without force?

There cannot be a force without motion and if there is no motion, then there is no force acting. (for example, students see a downward force of a book acting on a table, but they do not see an upward force of the table acting on the book.) When an object is moving the force is acting in the direction of its motion.

## Why is force equal to mass times acceleration?

This equation is one of the most useful in classical physics. It is a concise statement of Isaac Newton’s Second Law of Motion, holding both the proportions and vectors of the Second Law. It translates as: The net force on an object is equal to the mass of the object multiplied by the acceleration of the object.

## What factors affect acceleration?

Notice how mass and force affect acceleration. The acceleration of an object increases with increased force, decreases with increased mass, and is in the same direction as the force.

## Does more force mean more acceleration?

The greater the force that is applied to an object of a given mass, the more the object will accelerate. For example, doubling the force on the object doubles its acceleration. The relationship between mass and acceleration is different.

## Does force always cause acceleration?

Forces always cause objects to move. An object can experience two or more forces and not accelerate.

## Why does weight 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. … Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.

## Will a heavier object accelerate faster?

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass. … If the car drives faster, the air resistance force gets larger.

## Is force equal to weight?

Weight. The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

## Does speed affect inertia?

For both interpretations, the answer is ‘yes’ since force still acts in an opposite force on anything which has mass. As you accelerate, your velocity increases and therefore mass will increase. The increase in mass will bring about an opposite force. The greater the mass, the greater the inertia.

## How does adding force affect acceleration?

states that the acceleration of an object increases with increased force and decreases with increased mass. … Notice how mass and force affect acceleration. Newton’s second law. The acceleration of an object increases with increased force, decreases with increased mass, and is in the same direction as the force.
