The kinetic energy of an object is proportional to the square of its speed.
The higher the speed the more the kinetic energy.
it has more kinetic energy. if this is a problem for school, use the equation for kinetic energy.
It doesn't. Increasing speed affects the KINETIC energy.
Increasing the speed will increase the KINETIC energy, not the potential energy. Of course, the potential energy may eventually be converted into kinetic energy, for example if the object moves upwards.
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
Kinetic energy depends on mass and speed. It is not directly affected by any force; however, a force can, of course, make an object move faster or slower, and thus indirectly affect kinetic energy.
Use the formula for kinetic energy: KE = (1/2) mv2 (one-half times the mass times speed squared). Clearly, the amount of kinetic energy depends both on the mass and on the speed of the object.
Height directly affects gravitational potential energy, since this energy is equal to mgh (mass x gravity x height). Height does not affect kinetic energy, which depends on the speed, not on the height. Except indirectly - for example, if an object is falling down, its speed will usually increase.
His kinetic energy increases. Ek=0.5*mv^2, so as v (speed) increases, kinetic energy increases.

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.
