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.

∙ 11y agoSince the kinetic energy is proportional to the square of the velocity, the doubling of the velocity has greater effect.

Which would have greater effect on kinetic energy of an object doubling the mass or doubling the velocity?
the velocity is decreased
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.
What has a greater effect on an objects kentic energy doubling its mass or doulbing it speeed?
Speed (KE goes up by the square of the velocity).
The factor that has the greatest effect on kinetic energy is?
velocity!!
What is the effect of doubling speed?
Several effects - for example, you get to your destination faster. You also have a greater risk of an accident.

Does mass or speed effect more on kinetic energy?
Kinetic energy = 0.5 x mass x velocity^2. Your answer should be velocity.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.

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.
How does mass and speed effect kinetic energy?
Kinetic Energy is 1/2 mass x the square of speed (KE = 1/2 mv^2)
How does the mass and speed of an object affect the kinetic energy?
Kinetic Energy is 1/2 mass x the square of speed (KE = 1/2 mv^2)
What 2 factors effect an object's of kenetic energy?
Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.Kinetic energy is (1/2) x mass x velocity2.
Is the greater an objects velocity the stronger the gravitational force on it?
Gravitational forces between objects depend only on their masses and the distance between them. Velocity has no effect.
