Kinetic energy is proportional to the square of the speed. That means that with three times the speed you get nine times the energy.

What is the ratio of the kinetic energy if ball A has triple the mass and speed of ball B?
Triple the mass will triple the kinetic energy; triple the speed will increase it by a factor of 9 (32), so in total, ball A will have 27 times the kinetic energy of ball B.
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 makes an object have more kinetic energy?
An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly. An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly.
How does the kinetic energy change if the objects mass is twice as large?
Assuming the larger mass is moving at the same speed as the original mass, the kinetic energy will double.
Dose a heavier or lighter object have a greater kinetic energy?
Kinetic energy depends on mass, and speed. Since you can't easily change an object's mass, you would basically change its speed.

What happens to kinetic energy when the mass and speed of an object changes?
Any change in mass or speed will cause a change in kinetic energy.
How does the speed of molecules change when ice change to water?
Their speed - Kinetic Energy - increases as the solid melts.
What does independent variable and dependent variable mean and what they do?
It means that you can change one variable (the independent variable) freely, but that the other variable (the dependent variable) depends on the independent variable. For example, to calculate kinetic energy, the energy (for a given object) depends on the speed; if you change the speed, you change the kinetic energy. You can't change the kinetic energy directly, only indirectly by changing the speed.
Change in speed what kind of form of energy is that?
when you decrease or increase speed you are losing or gaining kinetic energy respectively
What makes an object have more kinetic energy?
An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly. An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly.
How does the kinetic energy of a body change if its momentum is halved?
Since momentum is proportional to the velocity, half the momentum means half the velocity (and therefore half the speed). And since kinetic energy is proportional to the SQUARE of the speed, half the speed means 1/4 the kinetic energy.
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.
