What KE describes the way energy is stored in a moving cricket bat?
KE means "kinetic energy" in this case. Kinetic energy refers to the energy of moving objects.
Which produces the greater change in kinetic energy exerting a 10-n force for a distanceof 5m or exerting a 20-n force over a distance of 2m?
Strictly this should be done in terms of line integrals but for a constant force the result simplifies tochange in KE = Force * distanceso 10N over 5m changes KE by 50J and 20N over 2m changes KE by 40J.
What happens to the force between two charges if the magnitude of both charges is doubled and the distance between them is cut in half?
The force between the two charges increases 16 times.Coulomb's law equation states:│F│ = ke │q1q2│/r2Where (F) is the force acting simultaneously on both point charges (q1) and (q2).r is the separation distance and ke is a proportionality constant called the Coulombconstant.Using above equation, if we double both charges and reduce the distance in half.│F2│ = ke │(2q12q2)│/(r/2)2 = 16 ke │q1q2│/r2 = 16 │F│.We see that the force turns out 16 times stronger
What has a greater effect on an objects kentic energy doubling its mass or doulbing it speeed?
Speed (KE goes up by the square of the velocity).
A feather and a coin dropped in a vacuum fall with equal?
ANSWER: the two objects would have the same velocity, but since KE is proportional to mass, the heavier one would have more KE.
How do you think the electrostatic force between two objects would change if the distance between two objects was doubled?

Do rapidly moving objects have more kinetic energy than slow moving objects?
Yes. The formula for kinetic energy is KE = 1/2mv2, where m is mass in kg and v is velocity in m/s. The greater the velocity, the greater the KE.

How do velocity and mass affect an objects kinetic energy?
The formula is: KE = (1/2) mv2
What type of effect does an objects speed have on its kinetic energy than a change in its mass?
KE = .5 m v2
If an objects velocity is doubled what happens to its inertia?
assuming its not starting at zero, if an object velocity is doubled, its kinetic energy (KE) is four times. If its trebled , its KE is nine times equation : KE = (m*v^2)/2 joules m=mass v=velocity

How do the mass and speed of an objects affect the kinetic energy?
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
How do you know when all of an objects kinetic energy is transferred into potential energy?
When the pendulum is at the top of its swing, the speed is zero so the KE is also zero.
