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 kinetic energy of the object?

The kinetic energy of an object increases as its speed increases, and decreases as its speed decreases. Kinetic energy is directly proportional to the square of the object's speed, meaning a small change in speed can have a significant impact on its kinetic energy.


What happens to an object's kinetic energy as its speed increases?

As an object's speed increases, its kinetic energy also increases. Kinetic energy is directly proportional to the square of the object's speed, so even a small increase in speed can result in a significant increase in kinetic energy.


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 happens to an object's kinetic energy when its speed doubles?

When an object's speed doubles, its kinetic energy increases by a factor of four. This relationship is due to the kinetic energy equation, which is proportional to the square of the velocity. Therefore, the object will have four times more kinetic energy when its speed doubles.

How does the kinetic energy of a body change if its momentum is halved?

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.

What happens to the kinetic energy when you increase the speed but keep the mass constant?

When you increase the speed while keeping mass constant, the kinetic energy increases. Kinetic energy is directly proportional to the square of the velocity, so as speed increases, kinetic energy increases even more rapidly.

particles speed up.


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).


As speed increases what happens to potential energy?

As speed increases, potential energy decreases. This is because potential energy is converted into kinetic energy as an object gains speed.


What happens to kinetic energy when an object is in motion?

When an object is in motion, its kinetic energy increases. Kinetic energy is the energy of motion, and it depends on the object's mass and speed. The faster an object moves or the heavier it is, the more kinetic energy it has.


What happens to the energy of a particle if the mass is constant and the speed increases?

The kinetic energy of the particle increases as the speed increases, following the equation ( KE = \frac{1}{2} mv^2 ) where ( KE ) is the kinetic energy, ( m ) is the mass of the particle, and ( v ) is the speed of the particle. The energy of the particle is converted to kinetic energy as its speed increases.
