Thus photon will have high momentum and a larger but indefinite amount of it will be transferred to the electron at the time of collision. This will result in greater uncertainty in the velocity of electron. On the other hand , decreasing the momentum means increasing the wave length which will lead to greater uncertainty in position. A light body and a heavy body have same linear momentum. Which one has greater K.E.? View Solution play_arrow; ... What will happen to the momentum? Will the momentum remain conserved ? (b) What will happen to the K.E ? ... If stretch in a spring of force constant k is doubled, calculate (a) ratio of final to initial force in the spring.Answer (1 of 6): actually I don't understand the motive of asking this question but since you have asked then I will try to cover all the possible effects when the velocity of a moving object is doubled .firstly as the velocity has been doubled then surely there would have been an acceleration an...What happens to momentum if mass is doubled? 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.Once things are moving relative to one another you have to factor in momentum. The full formula is E 2 = m 0 2 c 4 + p 2 c 2 where p is the object's momentum. E = mc 2 is what happens when the momentum is 0. Watch this Sixty Symbols video for more about that. Momentum is important for the Earth's orbit, specifically angular momentum per unit mass.Momentum is in the same direction as velocity. Scientists calculate momentum by multiplying the mass of the object by the velocity of the object. It is an indication of how hard it would be to stop the object. If you were running, you might have a mass of 50 kilograms and a velocity of 10 meters per second west (really fast). Oct 28, 2017 · The correct answer is Momentum is double. Key Points 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. Momentum = mass × velocity Momentum is directly proportional to velocity. What happens to the angular momentum of an object if its angular velocity is doubled? What happens to angular velocity of the object? Thus the angular momentum of the object must remain constant. Since L = Iσ, if I is doubled, σ must be halved. Thus the final angular velocity is equal to one half its original value.Ans : Its kinetic energy will be doubled. Question. What will happen to the kinetic energy of a body if its velocity is halved? Ans : The kinetic energy of the body will become one-fourth. Question. When a constant force is applied to a body moving with constant acceleration, is the power of the force constant?Sep 14, 2012 · (c) A girl of mass 40 kg jumps with a horizontal velocity of 5 ms 2 1 on to a stationarycart with frictionless wheels. The mass of the cart is 10 kg. Find her velocity as the cart starts moving. Assume that there is no external unbalanced force working in the horizontal direction. Sol. (a) When the velocity of aeroplane is doubled. Its momentum gets doubled but the momentum of air also gets increased by the same amount in opposite direction so that total momentum of plane and air remains conserved. (b) The kinetic energy will become four times additional energy will be obtained by burning of the fuel of the plane.When a skater skates in a straight line, linear momentum is the product of the skater's mass and velocity. When spinning, however, linear momentum changes to angular momentum. Angular momentum depends upon angular velocity and moment of inertia. Angular velocity is a measure of how quickly an object is spinning. Linear momentum is the product of a system’s mass and its velocity. In equation form, linear momentum p is. p = m v. 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. If the velocity of a body is halved, its kinetic energy becomes one fourth as kinetic energy is directly proportional to velocity squared. Byjus Asked on June 25, 2016 in Physics.What happens to the angular momentum of an object if its angular velocity is doubled? What happens to angular velocity of the object? Thus the angular momentum of the object must remain constant. Since L = Iσ, if I is doubled, σ must be halved. Thus the final angular velocity is equal to one half its original value.(C) momentum is doubled (D) potential energy is doubled Verified 98.1k + views Hint: Velocity is defined as the rate of change of position of an object with respect to time. And the velocity is also defined as the amount of distance travelled by an object in a given amount of time. By using the velocity formula, the solution can be determined.What happens to inertia when velocity is doubled? There is no change in the inertia when the velocity is doubled. Inertia is dependent only on the mass of the object. When the velocity of the object increases the momentum will be doubled.Sol. (a) When the velocity of aeroplane is doubled. Its momentum gets doubled but the momentum of air also gets increased by the same amount in opposite direction so that total momentum of plane and air remains conserved. (b) The kinetic energy will become four times additional energy will be obtained by burning of the fuel of the plane.MCQ Questions for Class 9 Science with Answers Physics. Q1. Among the equal-sized stone and a football, the inertia will be higher of: Q2. A water tank filled upto 2/3 of its height is moving with a uniform speed. On sudden application of the brake, the water in the tank would.Regarding this, what happens to velocity when kinetic energy is doubled? The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed is called its kinetic energy. Hence, when velocity is doubled, kinetic energy. becomes 4 times.When the velocity of a body is doubled A kinetic energy is doubled B acceleration is doubled. C momentum is doubled. D potential energy is doubled. Easy Solution Verified by Toppr Correct option is C) Momentum is directly proportional to the velocity, hence if velocity is doubled momentum will be doubled.
