Answer 2

1. a stationary object to move
2. an object moving to stop
3. moving object to change direction

Question 3

two categories of forces

Answer 3

contact forces and field/long range forces

Question 4

long range forces

Answer 4

forces that do not involve physical contact between two objects

Question 5

contact forces

Answer 5

forces that result from physical contact between two objects

Answer 10

FT

Question 11

Friction Force

Answer 11

Kinetic Friction (Ffk), Static Friction (Ffs)

Question 12

Gravitational Force (Fg)

Answer 12

• a force which hold you to the surface of Earth

Question 13

Magnetic Force (FM)

Answer 13

-non contact

Question 14

Electrostatic Force (Fe)

Answer 14

-non contact

Question 15

Spring Force (Fsp)

Question 16

Tension Force (FT)

Answer 16

-occurs with ropes, chains, strings, etc.
-only a pull

Question 17

Kinetic Friction Force (Ffk)

Answer 17

-friction that acts to slow down an object in motion
-sliding friction
-resistance force

Question 18

Static Friction (Ffs)

Answer 18

• fiction that acts when an object is “on the verge” of motion
  -Prevents object from moving
  -not moving but you can see that it could/ would move

Question 19

Centripetal Net Force

Answer 19

FNetc

Question 20

Centripetal net force (FNetc)

Answer 20

the net (total) force directed toward the center of an object’s circular path

Question 21

Tangential Velocity

Answer 21

VT

Question 22

Tangential Velocity (VT)

Answer 22

velocity at the line tangent to the circular path
(think straight line out of circle

Question 23

Centripetal Acceleration

Answer 23

(ac)

Question 24

Centripetal Acceleration (ac)

Answer 24

acceleration directed towards the center of a circular path

Question 25

Inertia

Answer 25

The tendency of an object to resist being moved or if already in motion to resist a change in speed or direction

Question 26

Issac Newton's First Law

Answer 26

a body at rest remains at rest. A body and motion remains in motion in a straight line at a constant speed unless acted upon by an unbalanced force

Question 27

Law of Inertia

Answer 27

-Objects continue to move by themselves -a force is needed to overcome friction and to set an object in motion initially

Question 28

How do we measure inertia?

Answer 28

Mass: the about of matter in an object, different from weight

Question 29

Normal Force

Answer 29

FN

Question 30

Normal Force (FN)

Answer 30

A force that acts on a surface in a direction perpendicular to the surface -molecules in a solid move -equal force from both objects

Question 31

Applied Force

Answer 31

(Fa)

Question 32

Applied Force (Fa)

Answer 32

used when talking about people or unknown forces being applied
