The word object is a very general term. A photon is also an object, and it does travel
at the speed of light. But it never travels at any other speed, so it doesn't "gain"
that speed. If we were to ask about objects made of atoms, then the answer is no,
they can never accelerate to the velocity of light. They can get arbitrarily close,
depending upon how much energy is used to accelerate them, but they can never
actually get to the full speed of light.
What else can I help you with?
Can an object have velocity more than light?
no
What is when an object could gain a velocity without an external force?
Gravity
What does an object do when it absorbs all light that strikes it?
the atom of the object will gain kinetic energy from the light
What height will it gain after the escape velocity becomes half?
That will depend not only on the escape velocity, but also - very importantly - on the object's speed.
Does an object gain momentum when it speeds up?
Yes The equation for momentum is mass x velocity So if you increase velocity the momentum increases
Can the Inertia of an object change as the object's velocity is changing?
No. What we call 'inertia' is actually a manifestation of the object's mass,which doesn't change (as long as the object isn't moving at some seriousfraction of light speed).
When a falling object has reached terminal velocity it continues to gain what?
When a falling object has reached terminal velocity, it no longer accelerates due to air resistance matching the force of gravity. At this point, the object continues to fall at a constant speed without gaining any additional velocity.
What describes how fast an object is moving and in what dirrection?
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
What is the equation for velocity approaching that the speed of light?
The equation for velocity approaching the speed of light is given by the relativistic velocity addition formula: v = (u + v') / (1 + u*v'/c^2), where v is the relative velocity between two objects, u is the velocity of the first object, v' is the velocity of the second object, and c is the speed of light in a vacuum.
Why does a moving object gain mass?
Mass is the sum of energies, both kinetic and potential. As the velocity increases so does the kinetic energy of object.
How can one determine the total velocity of an object by using the formula for velocity addition?
To determine the total velocity of an object using the formula for velocity addition, you would need to add the velocities of the object and the observer relative to a reference point. The formula for velocity addition is vtotal (vobject vobserver) / (1 (vobject vobserver / c2)), where vtotal is the total velocity, vobject is the velocity of the object, vobserver is the velocity of the observer, and c is the speed of light.
The speed of an object and the direction of its motion?
the object's 'velocity'
