What happens to kinetic energy if mass is reduced to half?

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.

When mass is reduced to 1 2 and speed is doubled What is the kinetic energy?

Answers and Solutions Let, mass=m, speed=v KE1= (1/2)mv^2 now, mass= m/2, speed= 2v KE2= (1/2). (m/2)(2v)^2=mv^2=2KE1,i.e., double of initial energy. Answer: Expl: New KE = 1/2.

What happens to kinetic energy when mass and velocity is halved?

Kinetic energy drops by half.

What happens to the kinetic energy when the speed is doubled?

The kinetic energy is proportional to the square of the speed, so doubling the speed increases the kinetic energy by a factor of 4.

What happens to kinetic energy when?

Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

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.

Which happens to kinetic if 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 of the body when both its mass and velocity are constant?

The kinetic energy of an object is the energy it has because of its motion. When we double the mass, we double the energy; however, when we double the velocity, energy increases by a factor of four.

What happens to kinetic energy when mass and velocity is doubled?

When the mass and velocity of the body are doubled, what happens to its kinetic energy? Kinetic energy is equal to half of the product mass and velocity.

When mass and speed of a body is doubled the kinetic energy increases?

The correct answer is becomes 4 times.

When the mass of a moving object is doubled with no change in speed by what factor?

When th mass of a moving object is doubled with no change in speed, by what factor is its momentum changed? Its kinetic energy? The momentum increases by 2. The kinetic energy increases by 2.
