Physics MCQ Answers Explained

The pressure exerted by air around us is known as atmospheric pressure.
The force exerted by the earth to pull the object towards itself is called gravitational force.
One Kilogram weight is equal to 9.8 N (Newton is the unit of force, and the gravitational force on 1 kg is 9.8 N).
When two forces act in opposite directions, the net force is the difference between the two forces.
Out of the options provided, the force of friction is a contact force as it requires two surfaces to be in contact.
