-- The area under a velocity/time graph, between two points in time, is the difference in displacement during that period of time.
-- The area under a speed/time graph, between two points in time, is the distance covered during that period of time.
Given that:
Energy of bulb (Work ) = 30 J,
Time (t) = 3 sec
The power consumption = ?
We know that, Power can be defined as rate of doing work
Power (P) = Work(Energy supplied) ÷ time
= 30 ÷ 3
= 10 Watts
<em> The power consumption is 10 W.</em>
Work
Explanation:
Energy can do work or bring about change.
Energy is simply the ability to do work. When work is done, changes occur in a body.
- There are different forms of energy and they are all related to work done.
- When work is done on a body, a force causes a change in that body.
- Both potential and kinetic energy are the same as work done.
- Energy is needed to do work.
- Work is done when a body changes energy.
