An object that normally doesn't move at light speed (so, this doesn't include photons for example) CANNOT move at the speed of light. As it approaches the speed of light, its mass will get higher and higher (and tend towards infinity); as will the energy required to continue speeding it up.
When any object with mass moves, no matter at what speed, its mass increases. The faster it moves, the faster its mass increases. And the closer to the speed of light it moves, the closer to infinity its mass grows.
An object such as a train simply CANNOT travel at the speed of light. You can investigate what happens when it moves close to the speed of light.
"Speed of light" is the correct term. Velocity refers to the speed of an object in a specific direction, while speed is the rate at which an object moves regardless of direction. The speed of light is approximately 299,792 kilometers per second in a vacuum.
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
No material object ever moves at the speed of light. The Earth's speed in its solar orbit ... relative to a foolish astronomer sitting on the sun ... is about 29.78 kilometers per second. That's about 0.0001 of the speed of light.
It means the speed at which light moves. While it may seem that light advances instantaneously, in fact it does not - it moves at a speed of 300,000 kilometers per second. That's the speed in a vacuum; in other substances, it moves slower. For example, in glass or water it moves at about 2/3 of the speed it has in a vacuum.
The speed that an object moves through the air.
When we say an object moves with constant speed, it means that the object is moving at the same rate without speeding up or slowing down.
No, distance and speed are two separate measurements. Distance is how far an object moves relative to speed and time, and speed is how fast an object moves relative to time and distance.
When an object moves, it acquires kinetic energy, which is the energy associated with its motion. This energy increases with the speed of the object and its mass.
The ratio of distance moved to the time taken to move that distance is the speed of the object. Speed is a measure of how quickly an object changes its position. Mathematically, speed = distance/time.
