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.
What is the relationship between energy and the speed?
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.
What will a car's kinetic energy be if the car's speed triples?
The Kinetic Energy Stays The Same
How does the average kinetic energy of a gas relate to its temperture?
The kinetic energy of a gas is the speed of motion of the gas molecules. The higher the speed of the molecules, the higher the kinetic energy and the higher the temperature.
Kinetic energy is related to an objects?
Kinetic energy is the energy of movement. It is related to an object's mass, and to its speed.
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.

What will happened to the ke if its velocity is reduced by 12 times?
Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.
Does kinetic energy increase with speed and time?
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
What is the speed of an object increases its kinetic energy .?
The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.
What is the relationship between energy and the speed?
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.
If the speed of an object doubles the kinetic energy of the object?
At twice the speed, the kinetic energy will be four times greater.
What happens to the kinetic energy when you increase the speed but keep the mass constant?
the speed will make the kinetic energy smaller.
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 will a car's kinetic energy be if the car's speed triples?
The Kinetic Energy Stays The Same
What does kinetic energy depend on in addition to speed?
Kinetic energy can be expressed by the equation: Ek= ½ mv2. Therefore in addition to speed (v), kinetic energy is also dependent on mass (m).
