# Is Velocity Dependent On Mass?

## What is difference between mass and velocity?

Answer: Velocity is the speed in a certain direction, e.g.

100mph north would be a velocity.

Mass is easiest understood as a measure of how hard it is to change that objects velocity*.

Mass is different from weight, which is mass times the strength of gravity..

## Do heavier objects have higher terminal velocity?

heavy objects will have a higher terminal velocity than light objects. … It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.

## Why mass does 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 terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object’s mass and directly proportional to the object’s velocity.

## How do you find velocity with time and mass?

Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth’s gravitational force as the acceleration rate of an object.

## What happens when velocity increases?

A positive velocity indicates that the position is increasing as time increases, while a negative velocity indicates that the position is decreasing with respect to time. … If the velocity remains constant on an interval of time, then the acceleration will be zero on the interval.

## Is force dependent on velocity?

The viscous force that a fluid exerts on a particle depends on velocity, F = F(v).

## What is velocity dependent?

Consider a particle of mass moving in one dimension under the action of a force, , which is a function of the particle’s speed, , but not of its displacement, .

## Does velocity increase as mass increases?

Therefore, it is safe to say that as the mass of an object increases so does its inertia. … Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally.

## Does force equal mass times velocity?

The second law explains how the velocity will change. The law defines a force to be equal to change in momentum (mass times velocity) per change in time. … For an object with a constant mass, the second law can be more easily expressed as the product of an object’s mass and it’s acceleration (F = ma).

## Does acceleration depend on mass?

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.

## What is the difference between velocity and momentum?

What is the difference between momentum and velocity? Momentum is dependent on mass, and velocity is independent of mass. The momentum is conserved in a closed system, but the velocity is not conserved. An external force is always required to change the velocity, but momentum can be changed by changing mass.

## 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. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.

## What is the relationship between acceleration and velocity?

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.

## Why does mass change with velocity?

As an object increases in speed, so does the amount of energy that it has, this energy is what we refer to as ‘the increase in mass’ (just remember, this is inertial mass). … Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well.

## What is mass velocity?

Mass flow rate across a unit area perpendicular to the direction of the velocity vector.

## Does mass affect velocity?

Mass does not affect the speed of falling objects, assuming there is only gravity acting on it. Both bullets will strike the ground at the same time. The horizontal force applied does not affect the downward motion of the bullets — only gravity and friction (air resistance), which is the same for both bullets.

## Is force and mass directly proportional?

Newton’s second law of motion (also known as the force law ) states that… net force is directly proportional to mass when acceleration is constant. …

## Can a body have a velocity without acceleration?

yes, a body moving with a constant speed has velocity without acceleration.

## What is the difference between acceleration and velocity?

Here are the basic definitions of velocity and acceleration: velocity – the rate of displacement of a moving object over time. acceleration – the rate of velocity change over time.
