Relation between force,work and energy in easy way for class 4
Dear Student
Force work and Energy
as shown in the figure a boy is pulling or pushing the cart that means boy is applying force on the cart,
When the cart moves from one place to other that mean work is performed
and when the boy is pushing or pulling the cart his energy is also lasting to performed the work
in the formula we can write
Work done =force x displacement
W=F x s
unit of work done is Joule
that work done can be written in the form of kinetic energy and potential energy
W=PE= mass x height x gravity=mgh Jpole
W=KE=1/2 (mv2)
where m is the mass and v is the velocity
Regards
