What else can I help you with?
Can any object move with the velocity of light?
No object that has mass when it's just sitting there on the table can move at the speed of light. Photons have zero "rest mass".
How can you tell an object has moved?
Because of its velocity (velocity is the rate of change of position), an object will move. An object is stationary if it has no velocity because it will not be able to move without velocity. Therefore, you can tell that an object has moved because of velocity.
How fast an object move?
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
What is the velocity if acceleration is zero?
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
What are the condtions for an object to stay at restto keep moving at constant velocity or to move with increasing velocity?
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
Why an object will move if its velocity is constant?
If an object's velocity is constant, it will continue to move at the same speed and in the same direction due to Newton's first law of motion. Unless an external force is applied, the object will maintain its state of motion.
How fast an object move and the direction it moves is called?
Velocity
What is the acceleration if velocity is zero?
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
What is the effect of gravity on velocity?
Gravity affects velocity by changing the acceleration of an object. As an object falls, gravity accelerates it, increasing its velocity. Without gravity, an object would move at a constant velocity.
What happens to the velocity when an object is accelerated?
A moving object being accelerated will show a change in its velocity (it may move faster, or slower, or experience a change in direction). A stationary object will respond to acceleration only if there is no other force acting to prevent its response. For example: gravity is a constant force of acceleration, but objects cannot move toward the center of the earth if they are being blocked by another object.
Why is no force required to move an object with a constant velocity?
Newton 2nd Law is the answer
Why velocity of current equal to velocity of light?
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
