Chapter 11 Forces

Question 1

Inertia

Answer 1

Tendency for an object to remain at rest or moving

Question 2

Newton’s First Law of Motion

Answer 2

an object at rest remains at rest and an object in motion maintains it velocity unless it experiences an unbalanced force

Question 3

Newton’s Second Law of Motion

Answer 3

The unbalanced force acting on an object equals the object’s mass times its acceleration

Question 4

Free Fall

Answer 4

When something is acted on only gravity/ said to weightless

Ex. Skydiver

Question 5

Terminal Velocity

Answer 5

Constant velocity of a falling object when air resistance force is equal in magnitude and oppose direction to the force of gravity

Question 6

Projectile Motion

Answer 6

Curved path an object follows when projected near Earths surface by the influence of gravity

Question 7

Law of Universal Gravitation

Answer 7

Particles attract other particles using the force directly

Question 8

Weight

Answer 8

.force exerted of body by gravity

Question 9

Apparent weightlessness

Answer 9

Property of objects that corresponds with how heavy they are

Question 10

Newton’s Third Law of Motion

Answer 10

For every action, there is an equal and opposite reaction

Question 11

Action Force

Answer 11

When your weight pushes down on something

Question 12

Reaction Force

Answer 12

When something pushes back with equal force
