Answer 1

Answer:

1. a push or a pull.

2.to push somebody/something suddenly or violently; to move quickly and suddenly in a particular direction

3.the force that is produced when you press on or against something

10. an instrument that measures air pressure and indicates changes in weatherA barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.

Answer 2

1. Any push or pull is called force
