If you double velocity the speed increases by [itex] sqrt(2) [/itex]
You go twice as fast? The momentum is doubled? The KE is multiplied by four? OK, none of that works under some specific conditions. For example, if the initial velocity is zero, none of the above happens.

What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.
What happens to the velocity of gas when temperature increase?
As temperature increases, so does molecular velocity, which also means volume increases.
Why KEof body increase when its speed is double?
KE = 1/2mv2, where m is mass in kg and v is velocity in m/s. If you double the velocity, KE quadruples.
What will happen to your kinetic energy if you double its objects velocity?
8
What happens to particles when thermal energy is given to them?
They move faster.
What happens to a car's velocity when you double its velocity?
If you double a car's velocity, its velocity will also double. This means that the car will be moving twice as fast as it was previously.
When does centripetal force double?
Since a=Rω², when you double the radius, but hold the angular velocity constant, you double the force. Also when you increase the angular velocity or velocity by a factor of √2 and hold the radius constant.
What happens when the velocity of the Earth is doubled?
If the velocity of Earth were to double, it would have 4 times the kinetic energy. Twice the current kinetic energy would already be enough to catapult the Earth away from the Sun - never to return.
How does velocity affect momentum?
if velocity increases, so does momentum. and vice versa momentum = mass x velocity increasing mass or velocity or both will increase momentum
What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.
What happens to an object's velocity when it accelerates?
"Acceleration" implies that the velocity changes.
What happens when you decrease the velocity of a car?
as you decrease the velocity of a car, you decrease the kinetic energy.
If an object moves with constant acceleration what happens to the velocity?
The velocity increases at a constant rate.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
What would be a passenger bus's new momentum if its velocity were double?
momentum is mass x velocity so if we double v then momentum becomes 2 times greater or double also
What happens to the velocity of bullet if there are two or more targets?
velocity decrease and at last it becomes zero.
When tossing a coin upwards what happens to its velocity while ascending what happens to its acceleration?
Its velocity decreases because gravity is pulling on it as it goes up. Its acceleration increases.
