Speed has the greatest influence on kinetic energy. However, we must not ignore the principle of conservation of energy. For example, when a ball is thrown from a height, the energy change is from gravitational potential energy to kinetic energy. Thus, height will determine kinetic energy. If the ball is thrown from rest, the initial speed will give rise to kinetic energy.

∙ 14y agowhen you want to know what variable has the biggest impact on something else, such as the kinetic energy, you write down the formula:
Ek = (1/2)mV^2
we notice straight away that the kinetic energy is proportional to V^2, but is only proportional to m, therefore increasing V will have the greatest effect on increasing Ek, where Ek is the kinetic energy.
making V a constant and plotting Ek against increasing mass would give a linear relationship between Ke and m, but doing the same with V would produce a parabola, which climbs much more quickly that the linear Ek vs M plot.

Kinetic Energy = 1/2 Mass x Velocity2 ,
therefore the K.E. increases as the SQUARE of the Velocity.

The factor that has the greatest effect on kinetic energy is?
velocity!!
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.
If you double the speed of a car you increase its force of impact by how many times?
four times as great
What two factors determine an object kinetic energy?
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
The factor that has the greatest effect on kinetic energy is?
velocity!!
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
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.

What is the primary factor in decreaseing the kinetic energy of an object?
Decreasing the mass or Decreasing the velocity
If you double the speed of a car you increase its force of impact by how many times?
four times as great
What is The primary factor in decreasing the Kinetic Energy of an object?
Important factors in decreasing Kinetic Energy are Gravity and 'drag' from Friction.
State any one factor which determines the kinetic energy of a body?
One factor affecting the kinetic energy of a particle (or body) in is the viscosity of the medium through which that particle moves
What is a exponential factor?
The exponential factor gives the proportion of collisions with kinetic energy greater than the activation energy
