What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
When a cars speed is doubled its kinetic energy is?
KE is increased by 4 times
What will happen to kinetic energy if vilocity is doubled?
Kinetic energy = (1/2)mv2, that is, (1/2) x mass x speed squared. As you can see, it is proportional to the square of the speed. Twice the speed would cause four (22 or 2 x 2) times the kinetic energy.
If speed is tripled then its kinetic energy of a mass is?
The formula for Kinetic Energy of an object is mv2/2 where m: mass of object and v:velocity of object Therefore when the speed of an object is tripled, then its kinetic energy becomes 9 times
Why is kinetic energy of an object four times larger when the speed doubles?
The expression for KE is 1/2 m v2 As v is doubled then KE will be 1/2 m (22) V2 So it becomes 4 times the original.
2009 tnpsc group 2 question paper?
when the speed of a body is doubled its kinetic energy becomes kinetic energy = 1\2 mv^2 speed = velocity kinetic energy = 1\2 m (2)^2 kinetic energy = 2 m so hence the answer is kinetic energy is quadrapole.

When a cars speed is doubled its kinetic energy is?
KE is increased by 4 times
Why does a small increase in speed produce a large increase in kinetic energy?
Kinetic energy is proportional to (depends upon) the square of the speed (velocity). If the speed is doubled then the KE is increased by a factor of 4 (2 squared).
Start with 20 joules if speed is doubled what is new kinetic energy?
80 (20 x 22).

How does kinetic energy affect speed?
The kinetic energy of an object is proportional to the square of its speed.
How does the speed of particle affect its kinetic energy?
The higher the speed the more the kinetic energy.
Does something have grater speed when it has more potential energy or less?
It can be a little complicated but I'll do my best to explain.Quick Vocab: potential energy - the stored energy in an object because of its position, shape, or condition. Kinetic energy - the energy of an object due to its motion. The more potential energy an object has the more Kinetic energy it will have. Basically when the object is moved the potential energy is released and becomes kinetic energy. As the kinetic energy (speed) increases the Potential energy decreases.So yes, when the potential energy decreases the speed increases.
What is the relationship between speed and kinetic energy?
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
