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
If you double the speed of a car you increase its force of impact by how many times?
four times as great
KE of an object when you double the velocity?
When you double the velocity of an object, the kinetic energy increases by a factor of 4. This is because kinetic energy is proportional to the square of the velocity according to the equation KE = 1/2 mv^2. So if you double the velocity (v), the kinetic energy (KE) will be four times greater.
How fast is a 4kg bird flying if it has 8 joules of kinetic energy?
Use the formula KE = 1/2 mv2 (kinetic energy = 1/2 times mass times velocity squared).Use the formula KE = 1/2 mv2 (kinetic energy = 1/2 times mass times velocity squared).Use the formula KE = 1/2 mv2 (kinetic energy = 1/2 times mass times velocity squared).Use the formula KE = 1/2 mv2 (kinetic energy = 1/2 times mass times velocity squared).
What will happen to kinetic energy if the velocity is doubled but the mass remains the same?
Kinetic energy will increase by a factor of four. Kinetic energy is proportional to the square of velocity, so if velocity is doubled, kinetic energy increases by four times. Since mass remains the same, there is no impact on kinetic energy from changes in mass.
What happens to velocity if you double kinetic energy?
The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.
What is a runners mass if the runner has a velocity of 4 ms and a kinetic energy of 3.9Nm?
.4875 kilograms but make sure your units are right on your question because that seems very small
If the speed of a moving object is doubled the kinetic energy of the object is?
The relation between kinetic energy is proportional to the square of velocity. Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time.
What is the KE of a 6kg mass at 4?
To calculate the kinetic energy, you need to know the speed of the mass in addition to its mass. The kinetic energy equation is KE = 0.5 * m * v^2, where m is mass and v is velocity. Without the speed of the mass, the kinetic energy cannot be determined.
Which object had more kinetic energy the one that has a mass of 2 kilograms or the one with the mass of 4 kilograms and was lifted at a rate of 3meters per second?
The object with the mass of 4 kilograms that was lifted at a rate of 3 meters per second would have more kinetic energy. Kinetic energy depends on both mass and velocity, so the increased mass more than compensated for the lower velocity compared to the 2-kilogram object.
Which is derived unit 1.mass 2.velocity 3.time 4.length?
velocity
If both the mass and velocity of a ball is tripled the kinetic energy is increased by a factor of?
When both the mass and velocity of a ball are tripled, the kinetic energy increases by a factor of 9. This is because kinetic energy is directly proportional to the square of the velocity, and also directly proportional to the mass. So tripling both the mass and velocity results in the kinetic energy increasing by 3^2 = 9 times the original value.
