Since momentum is proportional to the velocity, half the momentum means half the velocity (and therefore half the speed).

And since kinetic energy is proportional to the SQUARE of the speed, half the speed means 1/4 the kinetic energy.

Do larger particles move faster than smaller ones?

because they have a larger mass and require a greater energy to move at the same speed. KE=1/2mv2 where m is mass, v is velocity and KE is kinetic energy so for the same energy if the mass is doubled then v2 is halved, resulting in a slower speed


Two point charges q1 and q2 are located a distance r apart in a vacuum Which change to the charges will halve the magnitude of the electric charge between them?

Hello, some error in the words. Electric "force" not electric charge. A/s we increase the distance between the charges ./2 times then force between them will be halved.


Will density change if you split an object?

ANSWER:No. The mass will be halved but the density will remain the same. ___________________________________________________________The density will remain the same since the formula for density of an object is mass/volume. When you split and object, the mass is divided by 2, and the volume is divided by 2 (or whatever fraction you want to cut your item). If you would, compare mass/volume=mass divided by 2/volume divided by 2.


Radium-226 is a common isotope on earth but has a half-life of about 1600 years. why is there any radium at all?

. This is because it keeps getting halved, and something that keep getting cut in half will never reach zero.


When the pressure exerted on a confined gas at a constant temperature is doubled the volume of the gas is?

Pressure will be doubled as well, if done in the samevolume (so: not in a balloon I mean).(Gas law: p/T=constant )

What will happen to the kinetic energy of the body if the mass of the body is halved and velocity remains the same?

Kinetic energy will also be halved. Because kinetic energy is equal to 1/2 mv2


What happens to speed if kinetic energy halved?

Kinetic energy is determined by mass and velocity. The velocity is halved if you double the original mass, so the kinetic energy stays the same (unless the mass added has the same kinetic energy in the observer's reference frame as the original mass).


What happened to kinetic energy is speed is halved?

The formula for kinetic energy is: KE = mv^2, in which m is mass in kilograms and v is speed in meters/second, or m/s. The unit for kinetic energy is the Joule (J), which is one kilogram·m^2/s^2. If the speed of a mass is halved, it's kinetic energy will be reduced by one quarter. For example, if a 1 kg mass has a speed of 4 m/s, its kinetic energy = 1 kg(4 m/s)^2 = 16 J. If the speed of the 1 kg mass is halved to 2 m/s, its new kinetic energy = 1 kg(2 m/s)^2 = 4 J.

What happens to the potential energy of an object if the mass is halved?

If the mass of an object is halved, its potential energy will also be halved as potential energy is directly proportional to the mass of the object. This is because potential energy is determined by the mass of the object, the acceleration due to gravity, and the height at which the object is located.


What would be the momentum if the mass were halved?

momentum=mass * velocity if velocity remain unchanged, the momentum too will be halved ============================================== But wait! Haven't we all learned that momentum is conserved, and half of it doesn't just suddenly disappear ? If half of the mass of a moving object suddenly disconnects from the object and goes somewhere else, then half of the momentum must go along with that half of the mass, and the total momentum doesn't change. On the other hand, if Tinker-Bell flew by, waved her magic wand and sprinkled ferry dust on the moving object so that half of its mass truly ceased to exist, then in order to keep the total momentum constant, the object's velocity must double! The answer to the question is: No matter what happened to the massive moving object, or how it happened, total momentum doesn't change. It's the same today, tomorrow, and forever. Momentum of the total system is always conserved. If half of the mass is detached, you can't say the rest is the whole system. The whole system is together both halves. If both moving same velocity, momentum is divided. If that half stopped, half of the momentum goes to the force used to stop that.


How much do you decrease your kinetice energy when you decrease your speed by double?

Kinetic energy is given by mv2, where m is mass and v is speed. To obtain a result let me divide the new kinetic energy, m(v/2)2 (where the initial velocity is divided by two), by the initial velocity, mv2. (v2/4)/v2 = 1/4 The kinetic energy will be one fourth of what it was when the speed is halved.


What will happen to the momentum of an object if the mass of an object is cut in half?

If the mass of an object is cut in half, the momentum of the object will also be halved. This is because momentum is directly proportional to mass, so a decrease in mass will result in a proportional decrease in momentum.


What happened to kinetic energy if the magnitude is being halved?

Kinetic energy = 1/2 M V2 .Double the mass . . . doubles the KE.Cut the speed in half . . . reduces the KE to 1/4 .Do both . . . reduces the KE to 1/2 its original value.


What happens to the speed of body when kinetic energy increase by four times?

When the kinetic energy increases by four times, the speed of the body will double. The relationship between kinetic energy and speed is not linear, but rather quadratic. So if the kinetic energy increases by four times (2^2), the speed will increase by two times (2).


When the mass of a moving object is doubled and its speed remains the same its momentum?

When the mass of a moving object is doubled and its speed remains the same, its momentum also doubles. Momentum is directly proportional to mass, so doubling the mass will result in a doubling of the momentum regardless of the speed.


What will happen to the potential energy of a body when its height is kept the same if the mass of the body is halved?

according to the equation for potential energy of a body i.e.''mgh'' if mass of the body is halved m/2 keeping it hight same then its energy will become half as well...
