When the velocity of an object is tripled by what factor is its momentum changed? Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled.
What happens to kinetic energy when momentum is doubled?
If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time. Click to see full answer.
What determines the amount of momentum an object has?
The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
What happens when the velocity of a plane is doubled?
Also, when the velocity of a plane is doubled what is the momentum? The aerodynamic force depends on the square of the velocity. Doubling the velocity quadruples the force. The dependence of lift and drag on the square of the velocity has been known for more than a hundred years.
How does the square of velocity affect the aerodynamic force?
The aerodynamic force depends on the square of the velocity. Doubling the velocity quadruples the force. The dependence of lift and drag on the square of the velocity has been known for more than a hundred years. The Wright brothers used this information in the design of their first aircraft.
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.
When the velocity of an object is tripled by what factor is its momentum changed by what factor is its kinetic energy changed?
The equation for kinetic energy is KE=0.5×m×v2 K E = 0.5 × m × v 2 , where KE is kinetic energy, m is mass, and v is velocity. Since velocity is squared in the equation and if velocity triples, kinetic energy will increase by a factor of nine. Now, let's say momentum triples to 6 kg • m/s.
When the velocity of an object is tripled by what factor does its amount of velocity change movement by what factor does its kinetic energy change?
Answer: When the velocity triples, the kinetic energy goes up by a factor of 9 because the velocity gets squared while mass remains constant.
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.
When the speed of your car is tripled by what factor does its kinetic energy increase?
9If 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.
When an object's speed doubles its momentum changes by a factor of and its kinetic energy changes by a factor of?
Therefore, when the momentum is doubled, the kinetic energy goes up by a factor of 4.
Is the velocity of a car is tripled its kinetic energy is?
If the velocity (v) is tripled, the kinetic energy becomes, K′=21m(3v)2=9×21mv2=9K.
When the speed of your car is doubled by what factor does its kinetic energy increase?
4 timesWhen the speed of your car is doubled, by what factor does its kinetic energy increase? Therefore when you double the velocity, that value is then squared. Therefore your kinetic energy is increased by 4 times the original amount.
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.
What happens to the kinetic energy when the mass is tripled with a constant velocity?
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 will happen to the momentum of an object whose 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 to momentum when kinetic energy is doubled?
i.e. if kinetic energy of a particle is doubled the its momentum will becomes 2 times.
What happens to the kinetic energy of an object when its momentum is doubled?
If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time. Click to see full answer.
How do mass and velocity relate to momentum?
Mass and velocity are both directly proportional to the momentum. 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 is the momentum of an object?
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. What happens if mass and velocity are doubled?
How does aerodynamic force depend on velocity?
The aerodynamic force depends on the square of the velocity. Doubling the velocity quadruples the force. The dependence of lift and drag on the square of the velocity has been known for more than a hundred years. The Wright brothers used this information in the design of their first aircraft.
