What will happen to your kinetic energy if you double its objects velocity?
8
If the velocity of a moving body is doubled what does this do to kinetic energy and the momentun of the body?
The kinetic energy would be quadrupled, and the momentum would be doubled.
Why does a train have more kinetic energy then a car?
Kinetic Energy = 1/2 mv2 where m = mass and v = velocity A train has much more mass than a car. So even if they are travelling at the same speed, a train will have more kinetic energy than a car.
Why is there kinetic energy?
because there is kinetic energy.
Does mind have kinetic energy?
No, the mind does not possess kinetic energy. Kinetic energy is energy that is created by a force or motion.
Is it true that doubling an objects velocity will double its kinetic energy.?
No, that's not true.
A change in a objects speed has a what effect on its kinetic energy than a change in mass?
Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
Which would have greater effect on kinetic energy of an object doubling the mass or doubling the velocity?
the velocity is decreased
Where velocity is squared in the kinetic energy equation doubling an object's velocity will do what to its kinetic energy?
Multiply it by 4 (4 = 22)
How kinetic energy of an object changes when the speed of an abject doubles?
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
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
Which would have greater effect on kinetic energy of an object - doubling the mass or doubling the velocity?
Doubling mass affects kinetic energy in that the greater the mass, the greater the kinetic energy. OK, but if you have a 10kg mass traveling at 2m/s and it bumps into and sticks to a 10g mass, the resultant speed would be 1m/s. The momentum stays the same. KE before is 10*2*2/2= 20, while the KE after is 20*1*1/2= 10. So it is not that the above answer is wrong, but rather, you question is not clear.
KE of an object when you double the velocity?
Kinetic energy = 1/2 (Mass) (Velocity)2. Since KE is proportional to V2, doubling the velocity increases KE by 22 = a factor of 4.
When you double the mass of an object what will happen to the kinetic energy?
Double.
What is the relationship between a moving object mass and its kinetic energy?
Linear - double mass and you double kinetic energy (1/2 m v squared).
What two factors determine an object kinetic energy?
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
