## Why does acceleration not depend on mass?

Mass is intrinsic to matter, but weight is the force of gravity on that mass.

…

The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels, and thus the object’s weight, does..

## 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 happens when you double the mass?

If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

## What is the force required to keep an object moving?

According to Galileo and Newton, when is a force needed to keep an object moving? Only when friction (or some other oppositional force) is present is a force needed to keep an object moving. The net force equals mass times acceleration.

## Does acceleration depend on speed?

That’s because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction. … Acceleration occurs anytime an object’s speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous.

## Why does mass not affect projectile motion?

When an object is dropped from a tower, mass does not affect final velocity or time. … When writing equations of motion for a dropped object, mass is in the equations in 2 places and they cancel out. That is basically the reason that mass does not affect the results of analysis of a projectile.

## Does mass affect acceleration?

Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.

## What is law of acceleration and examples?

Newton’s Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.

## Is motion possible without force?

Yes, it is possible for motion to exist without force. An application of an external force is required to change the state of the motion. … When the force is removed, the object acquires a new constant speed/direction.

## 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.

## Do more massive objects fall faster?

As learned above, the amount of air resistance depends upon the speed of the object. … Thus, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.

## Do you keep accelerating in space?

You can keep accelerating as long as you have the means. … Due to the distorting effects of the theory of relativity on space and time, you can keep accelerating at a constant acceleration forever, and yet never hit the speed of light.

## Does Mass oppose acceleration?

The relationship between mass and acceleration is different. It is an inverse relationship. In an inverse relationship, when one variable increases, the other variable decreases. The greater the mass of an object, the less it will accelerate when a given force is applied.

## What is required to cause acceleration?

the rate of change of velocity is called as acceleration . so , change in velocity is required to form acceleration. and unbalanced forces also cause to form acceleration.

## What if I push an object which is already moving horizontally?

Thus, force would cause. acceleration in horizontal motion.

## What is the relationship between mass force and acceleration?

It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied. If the same force is applied to two objects of differ- ent mass, the heavier object has less acceleration than the lighter object (Figure 1).

## What keeps the object remain at rest?

Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia. A more massive object has more inertia than a less massive object.

## Why does mass resist acceleration?

More mass means more curved space and more inertia – more resistance to change of state. The curved space (gravity) of the object itself manifests as inertia when you try to change state of the object (e.g. from rest or uniform motion). Same curved space, manifests as gravity for other objects.

## Why is force equal to mass times acceleration?

Newton’s second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object’s acceleration.

## How much force is needed to keep an object moving?

It includes the law of inertia → if there is no force, F = 0, then the acceleration = 0 → the velocity doesn’t change → no force is needed to keep an object moving with constant velocity. If there is more than one force acting on an object, then F is the net force.

## Does Mass Affect force?

Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects. Example: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.
