Question

definition:
1. atmospheric pressure.
2. kinetic friction.
answer fast pls ​

Answer 1

Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air above that surface

a force that acts between moving surfaces. A body moving on the surface experiences a force in the opposite direction of its movement

Answer 2

That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. ...

Kinetic friction is defined as a force that acts between moving surfaces. A body moving on the surface experiences a force in the opposite direction of its movement. The magnitude of the force will depend on the coefficient of kinetic friction between the two material.
