Work,Energy and power

What do you mean by Kinetic Energy

• It can be stored in Fossil Fuels

• Its produced when object is stretched or compressed

• The energy due to movement

• It is energy which is produced when an object is raised to an certain height above the ground level.

Which one is form of Potential Energy

• Chemical Energy

• Elastic Potential Energy

• Gravitational potential energy

• All of the above

Chemical Potential Energy can be stored in..

• Moving car

• Fossil fuel like coal,oil.gas

• When rubber brand is stretched or compressed

• When hammering a nail

Why rubber brand is released

• Because it was stretched or compressed

• It had chemical energy stored in

• It converted to K.E(Kinetic Energy)

What is law of conservation of Energy

• Energy can neither created be nor be destroyed.It cannot change from one form to another.But the total amount of Energh remains constant.

• Energy can neither be created nor be destroyed.It can change from one form to another.But the total amount of Energy remains constant.

• Energy will only be constant.

• Energy will be destroyed and will change from one form to another.

When you are hammering a nail what applies?

• K.E --> Thermal energy and sound energy and kinetic energy is produced.

• Only gravitational potential energy is produced

• Chemical energy occurs

• K.E --> Gravitational potential energy and thermal energy and sound energy and kinetic energy is produced

A coal is burnt what applies?

• Chemical Energy --> Thermal and light energy were produced

• Only chemical energy produced

• Chemical Energy --> Thermal and light energy and kinetic energy produced

• Kinetic Energy --> Thermal Energy and Light energy

A bow is stretched which energy is applying?

• Chemical Potential Energy

• Elastic Potential Energy

• Gravitational Potential energy

• All of the above

A car is parked on top of a hill which energy is applying?

• Chemical Potential Energy

• Elastic Potential Energy

• Gravitational Potential Energy

• None of the above

Is Potential Energy is converted to Kinetic Energy?

• Yes

• No
