Can balance force bring a body to rest?
Balanced forces cannot bring a body to rest. Balanced forces can act on a body which is already at rest or in motion but equal forces cannot change a bodies acceleration, kinetic energy or momentum.
Can heat energy change into mechanical energy with equal ease and with the same efficiency?
yes
Factors affect heat gained or lost?
-heat capacity of the object (equal to mass times the specific heat capacity of the object) -overall change in temperature.
How does doing work on an object change its energy?
doing work changes the energy because energy is begining transferred to the object and the power will be equal to the amount of energy transferred.
What is laws of conservation of energy?
A conservation law, such as this one, can be stated in different ways; for example:* The total amount of energy in a closed system doesn't change over time.* Any change in energy in a system is equal to the energy that comes in, minus the energy that goes out.* There is a quantity called energy, that can't be created or destroyed.
Are all types of energy equal in their capacity to bring about changes?
yes just ask moses
How do you calculate change in energy?
The change in potential energy is equal to mass*gravity*change in height
If work done on an object is equal to object's change in kinetic energy this the state of?
the Work-Energy Theorem states the work done is equal to the change in kinetic energy.
Why is gravitational potential energy equal to kinetic ebergy?
Gravitational potential energy is not equal to kinetic energy:MGY doesn't always equal (1/2)mv2. This holds true in the CHANGE of gravitational potential energy being equal to the CHANGE in kinetic energy because of the Law of Conservation of Energy, Mass, and Charge.

Can heat energy change into mechanical energy with equal ease and with the same efficiency?
yes
How do you find kinetic energy if no final velocity is given?
Kinetic energy is equal to potential energy during the change
Did the Civil War bring about more change than the American Revolution?
i think equal
How many BTUs does a 1 ton unit equal?
A ton is the amount of cooling capacity (power), not energy. 1 ton is equal to 12,000 BTU/hr.
What is the amount of energy given off or absorbed when electrons change energy states equal to?
E=hv
Factors affect heat gained or lost?
-heat capacity of the object (equal to mass times the specific heat capacity of the object) -overall change in temperature.
How does energy change when work is done?
Energy changes and object is equal to the net work done. This is taught in science.
