Answer 2

Ratio between two different quantites

Ans: A ratio is a quantity that denotes the proportional amount or magnitude of one quantity relative to another or in short, it is the proportion of one to another.

Property of a body that resists any change in velocity

Ans: Inertia

mass of an object multiplied by its velocity

Ans: Momentum

upward force of air agianst a moving object

Ans: Up Thrust, lift or buoyancy

velocity in an up or down direction

Ans: Vertical motion

unit of measurment for force

Ans: Newton

a push or pull exerted on one body by another

Ans: Reaction

forces always come in ___ (magnitude and direction)

two objects with the same velocity must be moving in the same __ (direction)

a force that acts on all objects on earth

Ans: Gravity

the force that opposes the motion of two touching surfaces

Ans: Friction

the amount of force per unit area

Ans: Stress

Answer 3

1. ? 2. inertia or mass 3. drag would be an opposing, but not necessarily upward force on a moving object. 4. ? 5. Newton, in SI units. 6. force. 7. pairs? 8. "direction." 9. Gravity 10. Normal force. 11. pressure
