Question

Give two examples of each of the following in short 1:mascular force 2:gravitational force 3:frictional force 4:electrostatic force

Answer 1

examples of the following:

1. pulling the door or lifting any heavy object.
2. falling of apple into the ground from the tree
3. combing hair many times causes friction and leads to attraction of pieces of paper when you keep the comb closer to those pieces of paper
4. moving of electrons or charges

Answer 2

1.force apply by buffalo to push carts, force apply to lify a stone from the ground,

2.this is the force when a stone is thrown upwards, it falls to the ground, another is the earth moves around the sun in a fixed orbit ,etc because of gravitional force

3.When a ball rolls over a ground, it stops after sometimes because of frictional force, when we play football then it stops because of frictional force, etc

4.lightning ,when you rub the plastic comb in your hair for several times and bring near to the small pieces of paper it can attract them because of electrostatic force
