What is the ratio of the kinetic energy if ball A has triple the mass and speed of ball B?
The ratio of kinetic energy is 9:1. Kinetic energy is directly proportional to mass and speed squared, so if ball A has triple the mass and speed of ball B, the kinetic energy of ball A will be 9 times that of ball B.
Can the change in kinetic energy be negative?
Yes, the change in kinetic energy can be negative if the object's speed decreases, resulting in a decrease in kinetic energy.
A change in a objects speed has a what effect on its kinetic energy than a change in mass?
A change in an object's speed has a greater effect on its kinetic energy than a change in mass. Kinetic energy is proportional to the square of the velocity, so even a small change in speed can result in a significant change in kinetic energy. On the other hand, mass only affects kinetic energy linearly.
What happens to the kinetic energy of the object?
The kinetic energy of an object increases as its speed increases, and decreases as its speed decreases. Kinetic energy is directly proportional to the square of the object's speed, meaning a small change in speed can have a significant impact on its kinetic energy.
When work is done is there a change in kinetic energy?
Yes, when work is done on an object, there is usually a change in its kinetic energy. Work transfers energy to the object, which can result in an increase in its speed and therefore a change in its kinetic energy.

What form of energy is related to change in speed?
Kinetic energy is related to the change in speed of an object. As an object's speed increases, its kinetic energy also increases, and as its speed decreases, its kinetic energy decreases.
Can the change in kinetic energy be negative?
Yes, the change in kinetic energy can be negative if the object's speed decreases, resulting in a decrease in kinetic energy.

When the speed of a body is tripled what is the change in its kinetic energy?
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 give something 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.
When work is done is there a change in kinetic energy?
Yes, when work is done on an object, there is usually a change in its kinetic energy. Work transfers energy to the object, which can result in an increase in its speed and therefore a change in its kinetic energy.
How does energy and speed relate?
The speed of a wave is a property of the medium, changing the speed would need a change in the medium itself. If the medium doesn't change as a wave moves, the wave speed is steady. Formula: Speed = distance divided by time
How does the speed of molecules change when ice change to water?
Their speed - Kinetic Energy - increases as the solid melts.
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.
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.
