Question 9

The difference between velocity and speed is

Answer 9

Velocity is a vector quantity, while Scalar is a scalar quantity

Question 10

meters/second squared

Question 13

Oil Drop Diagram

Answer 13

Diagram that can show the distance that the object traveled at a constant time; can be used to show acceleration

Question 14

Acceleration is described as a

Answer 14

Vector Quantity

Question 15

Force is a

Answer 15

Push or pull;vector quantity

Question 16

An applied force is

Answer 16

a force that is given by us, whether it be pushing or pulling

Question 17

A tension force is

Answer 17

a force that ropes or strings make

Question 18

A tension force will always have the property that

Answer 18

It will always be a pull, and run across the entire string

Question 19

Gravitational force is always a

Answer 19

pull

Question 20

Normal force is

Answer 20

perpendicular to the surface, in physics along with math

Question 21

Frictional force is

Answer 21

always a push, and the resistance of the motion is in the opposite direction of what direction it is being pushed

Question 22

Thrust force is created when

Answer 22

a push happens in the opposite direction

Question 23

Drag force is created when

Answer 23

atoms and molecules push in the opposite direction of the object, sometimes slowing it down

Question 24

Air resistance is

Answer 24

a more specific drag force, in the air

Question 25

Buoyant force is

Answer 25

the force that happens when an object is in a fluid, pushing it against gravity. It is the force that makes things float

Question 26

Lift force is created when

Answer 26

molecules go really fast over and object, creating a force. it can be in any direction, up or down

Question 27

The unit used to describe force is

Answer 27

Newtons (N)

Question 28

A free body diagram (FBD) is used to

Answer 28

see the sum of the forces acting on an object

Question 29

Tendency of objects at rest

Answer 29

they stay at rest until an unbalanced force acts on it

Question 30

Tendency of objects in motion

Answer 30

they continue their motion with the same velocity unless an unbalanced force acts on it

Question 31

Inertia

Answer 31

the natural tendency of an object to continue doing whatever it is doing

Question 32

F=ma

Answer 32

Newton's Second Law

Question 33
