NO
four times as great
Not necessarily. In some places there is destructive interference, meaning there will be less energy, but in places where there is constructive interference, the amplitude of the wave will be up to twice the amplitude of the individual waves - and the energy up to four times as much.
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
Since Kinetic energy is defined as (1/2)mv2 thus if v was doubled the kinetic energy would quadruple (22).
The four states of matter are related by energy concentration.

The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.
four times
No.IF both objects have the same mass, then the faster one has twice the momentumand four times the kinetic energy of the slower one. If their masses are different, thennothing can be calculated until we know the masses.
Four times the amount of traction is needed
Four times as farther.
At twice the speed, the kinetic energy will be four times greater.
If several objects have the same speed and the same velocity,then each has the same kinetic energy.
Kinetic energy is proportional to velocity2, so if velocity is multiplied by four the kinetic energy is multiplied by sixteen
No, it is 4 times as great. Looking at the equation for kinetic energy: E=0.5 x m x v x v Where E=kinetic energy m = mass of vehicle v = velocity of vehicle If the vehicle weighs 1000 kg and is traveling at 10 m/s the kinetic energy possessed will be 1000 x 10 x 10 = 100,000 joules Whereas if the same vehicle is traveling at 20 m/s it would be 1000 x 20 x 20 = 400,000 joules. In other words, the vehicle possesses four times as much energy.
Kinetic energy, Ek = 1/2 mv2 Thus, Ek increases by 2 x 42 times => Ek increases by 32 times.
The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.
