What happens to momentum when velocity is tripled?
If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.
What will happen to the momentum of the object if the velocity is doubled?
If the velocity is doubled its kinetic energy is multiplied by four times. And there is no relationship between the velocity and potential energy. So, if the velocity is doubled, momentum also doubles.
What happens when speed is tripled?
If the speed triples, how does the kinetic energy change? The kinetic energy increases as the square of the speed. If the speed triples, how does the kinetic energy change? The kinetic energy increases by a factor of 9.
What happens to the kinetic energy if the mass and velocity was tripled?
1 Expert Answer 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 is the relationship between velocity and momentum?
p = m v . You can see from the equation that momentum is directly proportional to the object's mass (m) and velocity (v). Therefore, the greater an object's mass or the greater its velocity, the greater its momentum.
When velocity becomes three times the original velocity What is the new kinetic energy?
Answer: If velocity is increased three times, then its kinetic energy becomes 9 times the original value, because it is proportional to the square of the velocity. Hence, kinetic energy = 25 × 9 = 225 J.
When momentum of an object is tripled what happens to its kinetic energy?
Hence, if the momentum of a body is tripled, it's Kinetic energy will become nine times its original value.
When the velocity of an object is doubled by what factor is its momentum changed by what factor is its kinetic energy changed?
Thus, if the velocity of an object is doubled, its kinetic energy is increased by a factor of four.
When the momentum of an object is tripled what happens to its kinetic energy?
Hence, if the momentum of a body is tripled, it's Kinetic energy will become nine times its original value.
How is the kinetic energy of a body affected if its mass is tripled and velocity is one fourth?
Answer: If the mass is tripled, the new kinetic energy of the car will be three times greater than that of the previous case. If velocity becomes 1/4th, the new kinetic energy of the car will be 1/16 times that in the previous case.
Is momentum and velocity the same?
What is the difference between momentum and velocity? Momentum is dependent on mass, and velocity is independent of mass. The momentum is conserved in a closed system, but the velocity is not conserved. An external force is always required to change the velocity, but momentum can be changed by changing mass.
How is velocity related to momentum quizlet?
Momentum is directly proportional to mass and velocity. Describe the relationship between mass velocity and momentum. The greater the mass and velocity the greater the momentum. The impulse on an object is equal to the change in momentum.
How is kinetic energy of a moving vehicle affected if velocity is tripled?
If the velocity (v) is tripled, the kinetic energy becomes, K′=21m(3v)2=9×21mv2=9K.
When kinetic energy of a body becomes thrice its momentum becomes?
Solution : As `p = sqrt(2)m K ,` here K is kinetic energy , if it is made three times then momentum will become `sqrt(3)` times .
What will happen to the momentum if velocity is decreased?
(Momentum is a vector quantity because velocity is a vector). Decreasing either mass or velocity will decrease momentum. Some or all of the momentum of an object can be transferred to another object by colliding with it.
What happens to momentum when kinetic energy is doubled?
i.e. if kinetic energy of a particle is doubled the its momentum will becomes 2 times.
When a body triples his speed his kinetic energy becomes?
When a boy tripled his speed, his kinetic energy will becomes nine times.
What is momentum and collision?
Momentum is a vector quantity that depends on the direction of the object. Momentum is of interest during collisions between objects. When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces).
What is momentum class 9th?
Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object's momentum equals mass times velocity. Momentum = Mass x Velocity.
What is the relationship between momentum and velocity?
p = m v . You can see from the equation that momentum is directly proportional to the object's mass (m) and velocity (v). Therefore, the greater an object's mass or the greater its velocity, the greater its momentum. A large, fast-moving object has greater momentum than a smaller, slower object.
Is momentum defined as an object’s mass times its velocity?
Momentum (P) is equal to mass (M) times velocity (v).
How is the kinetic energy of a moving car affected if a its mass is tripled B its velocity becomes one fourth?
Answer: If the mass is tripled, the new kinetic energy of the car will be three times greater than that of the previous case. If velocity becomes 1/4th, the new kinetic energy of the car will be 1/16 times that in the previous case.
What happens to the kinetic energy if the velocity increases three times?
Hence, new kinetic energy becomes 9 times.
What happens to momentum when kinetic energy is increased by 300?
Hence, momentum will increase by 100%.
What can momentum be decreased by?
Decreasing either mass or velocity will decrease momentum. Some or all of the momentum of an object can be transferred to another object by colliding with it. Momentum is conserved during a collision unless some work is done (eg permanently bending something, generating sound, etc).
What does doubling an object’s velocity do to its momentum and to its kinetic energy?
What does doubling an object's velocity do to its momentum and to its kinetic energy? a) Doubling the velocity doubles the magnitude of the momentum and decreases the kinetic energy by a factor of four.
Does momentum increase after a collision?
In most collisions between two objects, one object slows down and loses momentum while the other object speeds up and gains momentum.
What happens to momentum when objects collide?
Momentum is of interest during collisions between objects. When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.
What is momentum in class 11?
Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object's momentum equals mass times velocity. Momentum = Mass x Velocity. Momentum is the quantity of motion and is compounded by the quantity of the matter moved and the velocity with which it moves.
What is impulse Byjus?
Impulse in Physics is a term that is used to describe or quantify the effect of force acting over time to change the momentum of an object. It is represented by the symbol J and usually expressed in Newton-seconds or kg m/s.
