What happens to energy during a phase change?
Energy either transfers to the object or leaves the object.
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.
When is kentic energy the greatest?
Kinetic energy depends on an object's mass, as well as on its speed. Since an object's mass usually doesn't change much, the kinetic energy will be greatest when the object moves fastest.
How does potential energy change to kinetic energy?
When the object changing its position from up per to a lower position.As an example an object falling from a building
Is kinetic energy is the energy an object has to due to its motion?
kinetic energy-energy in motion object that change from being at rest
What does an object have if it is able to produce a change in itself or its surrounding?
The object has energy.
When does light energy change to thermal energy?
When an object absorbs light energy the object can get warmer.
What happens to energy during a phase change?
Energy either transfers to the object or leaves the object.
What object is energy stored in to cause change?
potential energy
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.
What type of energy change results when friction slows an object down?
The kinetic energy of the object changes into thermal energy.
The term metabolism is based on a greek word that means change. How is change related to metabolism?
You need energy for metabolism and energy is the ability to cause a change
What does an object have if it is able to produce change in itself or its surroundings?
The object has energy.
What does an object have if it is able to produce a change in itself or it surroundings?
The object has energy.
What change of state and what energy changes occur when water freezes?
the state change is from liquid to solid and the energy change is cold energy to heat energy
Does an object mass change potential energy?
Kinematics
How can potencial energy change to kinetic energy?
yes it can, if you move the object it will gain kinetic energy
