What kind of energy transformation is taking place in the plant in the photograph?
What kind of energy transformation is taking place in the plant in the photograph?
Plants transform the Sun’s light energy into chemical energy during the process of photosynthesis.
What kind of energy transformation is taking place in the caterpillars body while the caterpillar eats the leaf in the photograph?
chemical energy
Which of the following describes the energy transformations that occur when a lamp is plugged in and turned on?
6th Grade study cards for Unit 5 Test; 3rd 6 weeks
| Question | Answer |
|---|---|
| Energy transformation that occurs when a switch is turned on a lamp… | #(electrical to light) |
| Kinetic energy is determined by an object’s mass and its… | #(speed) |
Which of the following is an example of energy transformation?
An example of an energy transformation that occurs in the natural world is the process of photosynthesis. In the Sun, chemical energy transforms into light and thermal energy. Plants transform the Sun’s light energy into chemical energy during the process of photosynthesis.
What 3 things does potential energy depend on?
The factors that affect an object’s gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in.
At what point is potential energy the greatest?
Potential energy is greatest when the most energy is stored. This could be when an object reaches its highest point in the air before falling, a rollercoaster just before it drops, or when a rubber band is stretched as far back as possible before it snaps. Potential energy is then converted to kinetic energy.
When work is done on a body does it gain energy?
Answer. it didn,t gain or loose energy. the energy of one type gets transformed into any other type
How is energy transferred when work is done?
When you do work on an object, some of your energy is transferred to the object. You can think of work as the transfer of energy. In fact, both work and energy are measured in the same unit, the joule. Energy can be transferred from the man to the ball, but the total amount of energy in the system does not change.
What is the difference between work power and energy?
Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt. One watt is equal to one joule per second. Power is a scalar quantity….Difference between Momentum and Inertia.
| Work | Power |
|---|---|
| Work is a scalar quantity. | Power is a scalar quantity. |
What kind of energy is force?
Any object that possesses mechanical energy – whether it is in the form of potential energy or kinetic energy – is able to do work. That is, its mechanical energy enables that object to apply a force to another object in order to cause it to be displaced.
