Homework Statement
From a uniform circular disc of radius 2 centimeter( its centre of mass is at 'O') , a circular portion of radius 1 cm is removed such that shift in centre of mass is maximum.The disc is now rotated about about 'O' perpendicular to the plane through an angle then the...
Yes,you are right.
During the horizontal motion
F= ma = kx
And during the vertical motion
F = mg = kx
If friction is taken into count that force also shall be taken into count.
Inertia is the property of bodies which always oppose the change of state.
If a body is in the state of rest because of inertia property it would like to continue its state of rest.
To change this state we need to apply force.
This gives foundation for Newton's first law.
