Its value grows to become precisely equal to double its initial value,
while its direction remains unchanged.
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.
Yes, two cars moving with the same velocity can collide if their paths intersect or if one fails to stop in time to avoid hitting the other. Velocity only describes the speed and direction of an object's motion, not its position. So, the cars can still collide if they have the same velocity.
Both cars would have the same momentum since momentum depends on both mass and velocity, and in this case, the cars have the same velocity and mass. So, the momentum of both cars would be equal.
if velocity increases, so does momentum. and vice versa momentum = mass x velocity increasing mass or velocity or both will increase momentum
"Acceleration" implies that the velocity changes.
Horsepower and aerodynamics
When cars are changing direction, they are also changing their velocity vector, which includes speed and direction. This change in velocity requires acceleration, which can be in the form of turning left or right, slowing down, or speeding up.
The velocity increases at a constant rate.
as you decrease the velocity of a car, you decrease the kinetic energy.
Double Trouble - The Cars song - was created in 1987.
momentum is mass x velocity so if we double v then momentum becomes 2 times greater or double also
velocity decrease and at last it becomes zero.
