What happens to the kinetic energy when the mass is doubled?
Answer and Explanation: The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.
What happens to the kinetic energy when a the mass of the body is doubled at constant velocity B the velocity of the body is doubled at constant mass?
Hence, (i) On doubling the mass, at a constant velocity, the K.E. becomes double its original value. (ii) On doubling the velocity, at constant mass, the K.E. becomes (2)2 i.e., 4 times its original value.
When the velocity of a moving object is halved Which of the following is also halved?
Kinetic energy is given by the formula ½ × m × v2, where m is the mass of the moving object and v is its velocity. Therefore, when speed is halved kinetic energy becomes ¼ of the original.
What happens to the Ke if its velocity is reduced by ¼TH of the initial velocity?
Now, the velocity is reduced to 1/3rd or the initial velocity. The final kinetic energy is given by. So, K.E. becomes 1/9th of its initial K.E.
What happens to the kinetic energy when the mass of the body is doubled but velocity is reduced to one fourth?
The energy of a body depends on mass and velocity. Kinetic energy is equal to half of the product mass and velocity. SI unit is joules. 1) If mass doubled then kinetic energy also gets doubled.
What happens to kinetic energy when mass is tripled?
The equation KE = ½ mv² shows that the relationship between Kinetic Energy and mass is directly proportional. a)So if the mass triples then the KE triples too. The relationship between Kinetic Energy and velocity is also directly proportional but with the square of the velocity.
How does the kinetic energy change if the velocity of a body is reduced by 1/3rd and its mass is doubled?
2..if velocity doubled with constant mass then kinetic energy becomes 4 times the initial kinetic energy.. 3..if mass doubled and velocity reduced to half kinetic energy will be half the initial value..
What happens to the kinetic energy of a moving body if its velocity is reduced by one third of the initial velocity?
