What is the frequency of the ke of a body in shm if the time period of shm is t?
If the period is ' t ', then the frequency is 1/t .
How the kinetic energy of an object changes when the speed of the object doubles?
Look at the formula for the kinetic energy of an object: KE = 1/2 M V2Did you notice that " V2 " ? That means the KE is proportional to the squareof the object's velocity.So if the object's speed doubles, its KE increases by (2)2 = a factor of 4.
What is PE and KE?
PE in physics is Potential Energy which means: energy an object has because of the position, shape, or condition of the object. KE in physics is Kinetic Energy which means: the energy of an object that is due to the object's motion.
When does a object have the most kinetic energy?
In the case of a falling object, the instant before the object hits the ground. U = KE + PE; PE=-KE . Inversely, the object has the highest potential energy (lowest kinetic energy) at the starting point of the fall.
When a object falls.. PE decreases and KE increases?
Correct.

If the period is ' t ', then the frequency is 1/t .
When kentic energy is passed from one object to another?
The first object loses KE and the second gains KE.
What is the mass of an object that has 9760000000 Joules of kinetic energy when it is moving at a speed of 236 meters per second?
A moving object has kinetic energy, KE, equal to 1/2 times its mass m times its velocity squared ,v^2 which is written: KE = (1/2)mv^2 since you know KE and v you can then solve for m.

Can an object have a non zero force and have constant kinetic energy?
an object can have a non zero force acting upon it if and only if the sum of all of the forces on the object is still equal to zero. The sum of the forces is equal to mass times acceleration. If an object is accelerating, then it does not have a constant KE therefore the sum of the forces must be equal to 0 so that acceleration is also equal to zero. For instance, take the case of an object falling through the air. Initially, the force of gravity is accelerating the object downward and it is gaining KE. After some time, this object will reach terminal velocity. At this point, the resistance force of the air on the object negates the force of gravity and the sum of the forces is equal to zero. The object now falls at a constant velocity and in turn also a constant KE. It is still being acted upon by the force of gravity and the resistance force but these forces are canceling each other out. =============================== I don't like to delete an answer that somebody put a lot of effort into, and supervisors don't like it when I become plainly uncomplimentary. So all I can say is: Use the above answer at your own extreme peril, and far better to ignore it. Especially the 1st and 3rd sentences.

Correct.
Why is KE equal to half mass velocity squared?
You can derive it from accelerating an object to a certain speed. Assume constant acceleration (and therefore constant force), and calculate how much work (force x distance) you need to get the object to a specific speed.
What two things do the kinetic energy of an object depend on?
KE = mv2 The mass and the squared velocity of the object.
What is KE?
Moving of an object releas the p.e due to aac.
KE of an object when you double the velocity?
Kinetic energy = 1/2 (Mass) (Velocity)2. Since KE is proportional to V2, doubling the velocity increases KE by 22 = a factor of 4.
