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 else can I help you with?
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).
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 do you notice about the relationship between kinetic energy and speed?
The relationship between kinetic energy and speed is directly proportional, meaning that as speed increases, kinetic energy also increases. This relationship is described by the kinetic energy formula, which states that kinetic energy is directly proportional to the square of the speed of an object.
How does the speed of an object affect the motion energy kinetic energy of the object?
The kinetic energy of an object increases with its speed because kinetic energy is directly proportional to the square of the object's speed. As the speed of an object increases, its kinetic energy also increases at a faster rate.
If the speed of an object increases its kinetic energy does what?
If the speed of an object increases, its kinetic energy also increases. Kinetic energy is directly proportional to the square of the object's speed, so a small increase in speed can result in a larger increase in kinetic energy.
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).
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.
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 happened to the ke if its velocity is reduced by 12 times?
Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.
Does kinetic energy increase with speed and time?
Kinetic energy increases with speed because kinetic energy is directly proportional to the square of an object's speed. Time does not have a direct effect on kinetic energy, as kinetic energy depends on an object's mass and speed but not its duration of movement.
How does kinetic energy affect speed?
The kinetic energy of an object is proportional to the square of its speed.
How does the speed of particle affect its kinetic energy?
The higher the speed the more the kinetic energy.

If the speed of an object increases, its kinetic energy also increases. Kinetic energy is directly proportional to the square of the object's speed, so a small increase in speed can result in a larger increase in kinetic energy.
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 form of energy is related to change in speed?
Kinetic energy is related to the change in speed of an object. As an object's speed increases, its kinetic energy also increases, and as its speed decreases, its kinetic energy decreases.
