Question

expalin these
1.inertia
2.work
3.energy
4.displacement

Answer 1

1 ) INERTIA :Inertia is also defined as the tendency of objects to keep moving in a straight line at a constant velocity. 

2 ) WORK : work is defined as the work expended by a force of one newton through a displacement of one metre.

3 ) DISPLACEMENT : The word displacement implies that an object has moved, or has been displaced. 

Answer 2

hey user,, it seems nice to see your question .
lets start

1) Inertia= The tendency of an object to resist a change in state of motion of an object is known as Inertia..
Inertia is also known as the first law of motion..

2) work = when a force applied to an object then ultimatley the object will get displaced ..then in that condition it is said that work is done ....
w = F×S

3)Energy = The capacity of doing work is known as energy ..

basically ,, energy is of two types
1) kinetic energy
2) potential energy ..

4) Displacement = when a force is applied on an object then it will cover a distance. that distance is said to be that displacement ...

hope it helps you ,, if you like my explaination then plz mark my answer as brainliest..
