What happens to kinetic energy when mass is constant and speed is tripled?

What happens to kinetic energy when mass is constant and speed is tripled?

1 Expert Answer 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. Hence, KE is 9 times greater.

What will be the kinetic energy if the mass is doubled?

Answer: The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.

Which factor contributes most to kinetic energy of a body in motion?

1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object’s kinetic energy. 2.

How fast can a man of 50kg run so that his kinetic energy be 625j?

v=5m/s.

How fast is a 50 kg man?

How fast should a man of 50?

Solution. So , the man should be running with a speed of 5 m/s .

How fast should a man of mass 60 kg run so that is kinetic energy is 750 Joule?

15m/s.

How fast would a 60 kg person have to run to have the same kinetic energy?

Answer. So,the man have to run at the rate of 5 metres per second.

How will the momentum of body change if its kinetic energy is doubled?

Momentum is directly proportional to velocity. If momentum of an object is doubled , but its mass does not increase (so velocity remains below the speed of light) then its velocity is doubled. If the velocity is doubled, then the kinetic energy increases by four times.

How fast can a man weighing 600n run to achieve a kinetic energy of 750 J?

5ms−1.

What is the definition of kinetic energy in physics?

Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.
