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 else can I help you with?
When a ball is thrown into the air the potential energy gained must come from its kinetic energy. As the ball gains potential energy its speed will?
decrease until it becomes zero at the ball's highest point
As the speed and length of wave decrease what happens to the wave?
As the speed and length of a wave decreases, the frequency of the wave remains constant. This means that the wave will experience a decrease in wavelength, which is inversely proportional to the decrease in speed. The energy of the wave will also decrease.
What will Kinetic energy be most affected by?
Kinetic energy will be most affected by an object's mass and speed. An increase in mass or speed will result in a higher kinetic energy. Conversely, a decrease in mass or speed will lead to a lower kinetic energy.
Does kinetic energy decrease when traveling up hill?
Yes, kinetic energy decreases when traveling uphill because some of the energy is converted into potential energy to overcome gravity. This results in a decrease in the speed of the object.
How are speed and pressure of a fluid related?
Speed and pressure of a fluid are related by the Bernoulli's principle, which states that as the speed of a fluid increases, its pressure decreases and vice versa. This is because the total energy of a fluid (kinetic energy from speed and potential energy from pressure) remains constant along a streamline. So, an increase in speed of a fluid leads to a decrease in pressure, and a decrease in speed leads to an increase in pressure.
Change in speed what kind of form of energy is that?
when you decrease or increase speed you are losing or gaining kinetic energy respectively

As the mass of an object moving at a given speed decreases its kinetic energy does what?
As the mass of an object moving at a given speed decreases, its kinetic energy also decreases proportionally. Kinetic energy is directly proportional to the mass of the object, so a decrease in mass will result in a decrease in kinetic energy.
What happens to potential energy if speed increases?
If speed increases, potential energy will decrease. This is because as an object gains speed, it will typically convert its potential energy into kinetic energy. The total mechanical energy of the system remains constant, but the distribution between potential and kinetic energy changes as speed increases.
How changes in energy will affect tranportation and stopping distances?
An increase in energy will generally result in an increase in speed, which will in turn increase the stopping distance required for a vehicle to come to a complete stop. This is because the kinetic energy of a moving vehicle is directly linked to its speed, so the greater the energy, the greater the speed, and consequently the greater the stopping distance needed. Conversely, a decrease in energy will result in a decrease in speed and stopping distance.
As the speed and length of a wave decrease what happens to the wave?
As the speed and length of a wave decrease, the frequency remains the same while the wavelength decreases. This means that the wave's energy decreases as well.
Can the change in kinetic energy be negative?
Yes, the change in kinetic energy can be negative if the object's speed decreases, resulting in a decrease in kinetic energy.
When a moving car slows down it's kinetic energy decrease?
When a moving car slows down, its kinetic energy decreases because kinetic energy is directly related to an object's speed. As the car decelerates, its speed decreases, causing its kinetic energy to decrease as well. This energy is ultimately transferred into other forms, such as heat generated by the brakes.
