Newtons Laws Vocab

Question 1

Equilibrium Rule

Answer 1

Equation

Question 2

Force

Answer 2

Push or a pull

Question 3

Inertia

Answer 3

The property by which things tend to remain at rest, and in motion

Question 4

Net force

Answer 4

The sum of all forces that act on an object

Question 5

Newton

Answer 5

The scientific unit of force

Question 6

Newton’s first law of motion-the law of inertia

Answer 6

Every object continues in a state if rest, or in a state of motion in a straight line at constant speed, unless acted on by a nonzero net force

Question 7

Speed

Answer 7

The distance traveled per time

Question 8

Support force

Answer 8

The force that supports an object against gravity

Question 9

Vector quantity

Answer 9

A quantity that specifies direction as well as magnitude

Question 10

Velocity

Answer 10

The speed of an object and specification of its direction of motion

Question 11

Acceleration

Answer 11

The rate at which velocity changes with time; the change may be in magnitude or direction or both

Question 12

Air drag

Answer 12

Frictional resistance due to motion through air

Question 13

Free fall

Answer 13

Motion under the influence or gravitational pull only

Question 14

Friction

Answer 14

The resistive force that opposes the motion or attempted motion of an object past another

Question 15

Inversely

Answer 15

When two values change in opposite directions, so that if one increases and the other decreases by the same amount, they are said to be inversely proportional to each other

Question 16

Kilogram

Answer 16

The fundamental SI unit of mass. One kilogram (symbol kg) is the mass of 1 liter (L) of water of 4. Degree C

Question 17

Mass

Answer 17

The amount of matter in an object; the more mass an object has, the more it resists changes in motion

Question 18

Newtons Second Law

Answer 18

The acceleration produced by a net force on an object is directly proportional to the net force, is in the same direction as the net force, and is inversely proportional to the mass of the object

Question 19

Terminal speed

Answer 19

The speed at which the acceleration of falling object terminates because air drag balances it’s weight

Question 20

Terminal velocity

Answer 20

Terminal speed with direction of motion ( down for falling objects)

Question 21

Volume

Answer 21

The quantity of space of an object occupies

Question 22

Weight

Answer 22

The force due to gravity of an object

Question 23

Force pair

Answer 23

The action and reaction pair of forces that occur in an interaction

Question 24

Interaction

Answer 24

Mutual action between objects in which each object exerts an equal and opposite force on the other

Question 25

Newton’s third law

Answer 25

Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. Of put another way, “to every action there is always an opposed equal reaction”

Question 26

System

Answer 26

Any object or collection of objects being studied
