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.


What is the relationship between speed and kinetic energy?

The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.


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.

Does kinetic energy increase with speed and time?

Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.


What is the speed of an object increases its kinetic energy .?

The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.


Why kinetic energy of a body is maximum at earth?

That's only true when the body is dropped from some height. In that case, its speed keeps increasing until it hits the ground, so that's when it's speed is the greatest, and more speed means more kinetic energy. If you fire a bullet, a golf ball, or a canonball horizontally, then its kinetic energy can easily be greater when it leaves the muzzle or the club-face than it is when the projectile hits the ground.


What is the relationship between energy and the speed?

The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.


If the speed of an object doubles the kinetic energy of the object?

At twice the speed, the kinetic energy will be four times greater.


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

the speed will make the kinetic energy smaller.


When the speed of a body is tripled what is the change in its kinetic energy?

Kinetic energy is proportional to the square of the speed. That means that with three times the speed you get nine times the energy.


What will a car's kinetic energy be if the car's speed triples?

The Kinetic Energy Stays The Same
