When the speed of an object doubles does its kinetic energy double too?

Answer: Speed is distance over time (V=x/t). The kinetic energy of an object is calculated from the type KE=1/2mass by Speed squared. From these two formulas we can see that if the speed doubles, then the kinetic energy of an object becomes four times larger. Lets see an example: A car has a speed of 4 metres per second. Its kinetic energy is KE=1/2mass by speed squared, so its KE=1/2mass by 16 (since the square of 4 is 16). If the speed doubles and the car does 8 metres per second, its kinetic energy is: KE=1/2mass by 64 (since 8 squared gives us 64). If we divide 64/16 its 4. So we see that when speed doubles, the Kinetic Energy of an object becomes four times larger.

∙ 13y agoKinetic energy is proportional to 1. Mass 2. Velocity2. So if the mass doubles the energy doubles. For velocity, if the energy doubles, the velocity must have increased by the square root of 2 (assuming mass is constant). If both mass and velocity are varying at the same time (as in a rocket launch for example) you would have to compute the kinetic energy at time intervals to see how it varies.

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
What happens to an object's kinetic energy when its speed doubles?
-It increases
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.
How kinetic energy of an object changes when the speed of an abject doubles?
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
If the of an object doubles Its kinetic energy doubles?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
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.
When you double the mass of an object what will happen to the kinetic energy?
Double.

What is the relationship between a moving object mass and its kinetic energy?
Linear - double mass and you double kinetic energy (1/2 m v squared).

What does it mean if an object has no kinetic energy?
an object has no kinetic energy if it is not moving
What does it mean if an object has kinetic energy?
an object has no kinetic energy if it is not moving
Explain how the kinetic energy of an object changes when the speed of the object doubles?
Kinetic energy is (1/2) (mass) (speed)2 .The only part of that formula we need in order to answer the question isthe (speed)2 part. It says that if you multiply the speed by 'K', then thekinetic energy gets multiplied by K2 .So if you double the speed, the kinetic energy is multiplied by (2)2 = 4 .
