What will happen to the kinetic energy of the object when mass and velocity are doubled?

If mass is doubled, leaving velocity constant, Ke is doubled. If velocity is doubled leaving mass constant, kinetic energy is increased four times.

Whats the relationship between mass and kinetic energy?

Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity.

How do mass and velocity affect kinetic energy as it increases?

Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.

What happens to the kinetic energy when the mass is constant and the speed 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.

What happens to the kinetic energy of an object?

The change in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. If the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy.

How will the kinetic energy of the car vary if its mass is halved?

Hence, when the speed of the car is halved the kinetic energy becomes one-fourth.

When the kinetic energy is halved in magnitude what happens to its momentum?

Halving the kinetic energy means either halving the mass or reducing the speed by – or a bit of both: Halving the mass will also halve the momentum . But reducing the speed by will not halve the momentum: So, kinetic energy and momentum are two properties that do not follow each other.
