What are non contact force?

Define contact force

What are conservative forces ? Give an example.

Which of the following is an example of a non-contact force _____ the force exerted by us to lift a bucket square hit a cricket ball for runs square the force exerted by magnet square push a stationary car square

Statement I: If a car is taking a turn on a banked road, then the normal contact force between car and road is greater than the weight of car (neglecting friction). Statement II: On a banked road, horizontal component of normal contact force between car and road provides necessary centripetal force. Assume friction is absent.

What are non-metals?

Three blocks are pushed with a force F across a frictionless table as shown in figure . Let N_1 be the contact force between the left two blocks and N_2 be the contact force between the right two blocks. Then

Two blocks of 2 kg and 1kg are in contact on a frictionless table. If a force of 3N is applied on 2kg block, then the force of contact between the two blocks will be

Three blocks of mass 4 kg, 2 kg, 1 kg respectively are in contact on a frictionless table as shown in the figure. If a force of 14 N is applied on the 4 kg block, the contact force between the 4 kg and the 2 kg block will be
