You'te fishing for "Einstein", but he didn't say that. He simply figured out how much
the mass of an object changes when the object moves at any speed. He left it for
others to discover that his formulas are true, and that if they're true, the mass of
any object is infinite at the speed of light, and since it would take infinite energy to
make infinite mass move that fast, and since nobody has access to infinite energy,
no object that has any mass can speed up to the speed of light, so it certainly can't
go faster than that.
Not necessarily. The speed of an object is influenced by various factors such as force, acceleration, and resistance. While a lower mass object may have a tendency to accelerate more quickly, it doesn't always mean it will travel faster than a high mass object in all situations.
According to the theory of relativity, it is currently believed to be impossible for any object with mass to travel faster than the speed of light in a vacuum.
According to the theory of relativity, it is not possible for any object with mass to travel faster than the speed of light in a vacuum, which is about 186,282 miles per second.
Heat=energy. The higher the heat, the higher the energy. Particles travel faster because they have more energy.
An object shaped like a streamlined teardrop or a streamlined cone would travel faster through the air due to reduced air resistance. These shapes help minimize drag and turbulence, allowing the object to move more efficiently and with less resistance.
Assuming equal conditions, a light object will generally travel faster than a heavy object due to having less mass to accelerate. This is consistent with Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
You cannot travel at the speed of light. Period.
If an object is more streamlined it will create less friction with the air and so it will be able to travel faster
Air sound travels slower when going through a solid object
According to scientific theories, there is no such thing which exists in the universe faster than light. Einstein proposed the theory that if scientists could make anything which can travel faster than light that that could travel in time or in other words scientist could actually make a time machine
Nobody knows for sure. We have never witnessed a physical object traveling faster than the speed of light.
Friction is force that opposes an objects motion. Therefore, the less friction the object encounters, the less opposition it will have to its direction of travel. The less opposition it has, the faster it may go. Theoretically, a moving object that encounters no friction will continue to travel at a constant rate for EVER.
