Yes. It is different for different planets etc. Escape velocity on earth is different than escape velocity on Jupiter.

Why all objects travel at the same velocity?

All objects do not travel at the same velocity. As an example, you should take a few minutes and think about an earthworm and a jet airliner.

Do Two objects of different masses fall with same velocity?

Yes. Neglecting the effects of air resistance, ALL objects fall with the same acceleration near the surface of the earth, meaning that any two objects dropped at the same time will have the same velocity after the same time interval.

Who discovered that all objectsheavy or lightfall the same velocity?

Galileo Galilei was the first to explain that heavy and light objects would fall the same way in a vacuum. Keep in mind, objects do not fall with 'velocity,' but with 'acceleration.'

Will the objects attract in the space?

According to the classic Theory of Gravity described by Isaac Newton, all objects are attracted to one another at some infantesimal level. In the absence of any other objects, any 2 objects will eventually be drawn together and collide, assuming they are not moving away from each other at escape velocity. Escape velocity is the velocity at which an object will be slowed by the object it is escaping but will never be stopped and drawn back. In short, yes.

Is escape velocity of light infinity?

Not at all. It would take an infinitely large mass to produce an infinite escape velocity, and no such infinite mass exists. Furthermore, the escape velocity for any object is the same no matter what is trying to escape, so light does not have its own escape velocity. This question presumably concerns black holes. Light does not escape from black holes because the escape velocity is greater than the speed of light. The speed of light is not infinite, it is 300,000 kilometers per second.

Do things fall at the same speed?

In the absence of an atmosphere, all objects will fall with the same acceleration. If two objects of different mass begin with zero velocity and are released at the same time, they will fall at the same speed.

How is the name black hole related to escape velocity?

The word "black" aptly describes the inability of light to escape - all light and matter that passes the event horizon can only do so in one direction, falling in. The reason is, the escape velocity inside the event horizon is greater than the speed of light, the event horizon itself being the boundary at which the escape velocity is equal to that speed. Outside that horizon, the escape velocity is less than the speed of light, hence it would be possible for light and objects moving at speeds approaching that of light to escape.

Why does a heavier object fall with the same accelerate as a lighter object?

all objects have a terminal velocity once youu reach terminal velocity you can not fall any faster

All objects have momentum?

momentum=mass*velocity if velocity is zero.momentum also zero

Is there more force created when 2 objects meet in motion or when 1 object is still?

Assuming all of the objects have the same mass, the answer depends on their combined velocities. If the combined vector component of velocity of two objects is the same as the velocity of the single moving object, then the force of impact will be the same. So if the two are moving in opposite directions along the same path, they will generate the same amount of force as a single object moving at a velocity that is equal to the combined velocities of the two. If the velocities are different, the force varies accordingly.

Can you Explain the concept that all objects have momentum?

If all objects have energy as in E=mc^2 then all objects have momentum P= mc. The universe consists of two types of "objects" scalars and vectors. Scalar momentum =mc, and Vector momentum =mv. If you only consider vector momentum then only objects with velocity have momentum. Here the problem is the Relativity of velocity. If there is no relative velocity then there is no vector momentum. There still is scalar momentum mc for all objects.

Why don't all objects fall to earth at the same velocity?

Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.

Why don't all objects fall to the earth at the same velocity even though the acceleration?

The acceleration is the same for all objects, as long as air resistance is insignificant. After a while, different objects will have different amount of air resistance. Also, even without air resistance, the speed depends not only on the acceleration, but also on how how long the objects are falling.

What If you have four balls all traveling at 5 meters per second which one has the most kinetic energy?

If several objects have the same speed and the same velocity,then each has the same kinetic energy.

In freefall do all objects near Earth's surface have the same acceleration?

Without atmospheric drag, all free falling objects near earth's surface will have the same acceleration. But because of friction with the air (air resistance), the velocity of objects due to that acceleration is limited. The actual velocity is dependent on the surface area of the object relative to its mass. The principle of the parachute is to increase the surface area of a falling object with respect to its mass.

In an explosion why do the smallest part that travel fastest and the furthest do the most damage?

the momentum of all the objects are the same so velocity is greatest at greater distances.

Do two different objects have the same terminal velocity?

No. An object's terminal velocity depends on how much air it must push aside while it falls, and if there were no air, there would be no such thing as terminal velocity. In air, different objects have different terminal velocities, depending on their weight and shape. All of this is the main reason that parachutes are popular for activities where falling is involved.

How does density effect gravity?

Not at all. The force of gravity between two objects depends only on their masses and the distance between their centers. Their volumes have no effect. Another answer: As for as one object goes: Density of an object increases the escape velocity (or escape speed) which increases the gravitational force.

A rocket that moves upward from earth's surface at escape velocity will?

Escape the earth's gravitational pull and continue out into space. However, a rocket does not need to be launched at the escape velocity as it can continue to accelerate as it climbs. A gun projectile would need to be fired with the escape velocity. In a perfect system with only the projectile and the Earth: If the projectile is fired with the exact escape velocity it will travel to infinity away from the Earth. Upon reaching infinitely far away from Earth the projectile would have zero velocity. All of its kinetic energy (movement) would be transferred to potential energy.

What is the word that causes all objects to fall at different speeds?

In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.

Why is momentum caused?

momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.

If two objects have the same momentum do their magnitudes necessarily have the same directions?

First of all ... I think you're talking about either the magnitude of the momentum, or the magnitudeof the velocity, not the magnitude of the objects.Now ... you're obviously skating around the subject of vectors here, recognizing that both thevelocity and the momentum are vector quantities.If, as you say, the two objects have " ... the same momentum ... ", then you're saying that theirmomentum vectors are equal. If so, then you'd have to say that yes, since the momentum vectorsare equal, the momentum vectors and the velocity vectors must all have the same direction.But if the two momenta only have equal magnitudes, then they ... and the velocities ... can be inany two directions, not necessarily related.
