100
It is the upward thrust.
What is buoyancy ?
100
when a force is applied and which is produced to certain displacement.
When is work said to be done?
100
it is the capacity to do work.
What is energy?
100
power is the rate of doing work.
What is power?
200
the perpendicular force acting on the surface of the body.
What is thrust?
200
it is joule.
What is the SI unit of work?
200
mechanical energy,kinetic energy,potential energy,light energy,solar energy,wind energy,heat energy
What are the forms of energy?
200
its unit of power is watt.
What is the unit of power?
300
its SI unit is newton.
What is the SI unit of thrust?
300
it is the amount of work done when a force of one newton produces a displacement of one meter in the direction of application of the work.
What is one joule?
300
kinetic energy and potential energy.
What are the two types of mechanical energy?
300
1 kilowatt=1000 watt.
What is 1 kilowatt in watt?
400
its SI unit is pascals
What is the SI unit of pressure?
400
when there is no displacement by the body even though force is applied and vice verse
When is the work said to be zero?
400
it is the energy can neither be created nor destroyed.
What is law of conservation of energy?
400
watt does the work at one joule per second.
