## Tags and Description

### 56 Terms

1

force

A push or pull upon an object resulting from the object's interaction with another object.

New cards
2

Vector Quantity

The Physical quantity that has both directions as well as magnitude

New cards
3

Magnitude

Represents the strength and the Direction of the force exerted.

New cards
4

balanced force

when 2 forces act on an object that is equal in size but are opposite in direction, we say the forces are?

New cards
5

unbalanced Force

when 2 forces are acting on an object and are not equal in size, we say the forces are?

New cards
6

Net Force

overall force acting on an object or a combination of the magnitude and the direction

New cards
7

Aristotle

He made pioneering contributions to all fields of philosophy and science, he invented the field of formal logic, and he identified the various scientific disciplines and explored their relationships to each other. He was also a teacher and founded his own school in Athens, known as the Lyceum.

New cards
8

Galileo Galilei

He used an Archimedean model of floating bodies, and later the balance, argues that there is only one principle of motionāheaviness. Bodies move upward not because they have a natural lightness, he says, but because they are displaced or extruded by other heavier bodies moving downward.

New cards
9

Isaac Newton

is popularly remembered as the man who saw an apple fall from a tree, and was inspired to invent the theory of gravity. If you have grappled with elementary physics then you know that he invented calculus and the three laws of motion upon which all of mechanics is based.

New cards
10

Law of Inertia

An object will not change its motion unless a force acts on it. What law of motion is this? (name of law not number,Add "Law of")

New cards
11

Mass

Less inertia has less?

New cards
12

Friction

Force present on the surface in contact with the object that tends to oppose the force acting on a body

New cards
13

Law of Acceleration

a quantitative description of the changes a force can produce in the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ( NAME OF LAW NOT NUMBER, ADD" LAW OF")

New cards
14

a= F/m

What is the formula to find Acceleration? (Use parentheses "(a)" for multiplication, And the slash sign "/" for division)

New cards
15

F=(m)(a)

What is the formula to find Force? (Use parentheses "(F)" for multiplication, And the slash sign "/" for division)

New cards
16

m=F/a

What is the formula to find mass? (Use parentheses "(F)" for multiplication, And the slash sign "/" for division)

New cards
17

acceleration

m/s^2 is the unit sign of?

New cards
18

Force

N is the unit sign of?

New cards
19

Mass

Kg/g is the unit of?

New cards
20

Law of Action and Reaction

for every action (force) in nature, there is an equal and opposite reaction ( NAME OF LAW NOT NUMBER, ADD" LAW OF")

New cards
21

Beaker

are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations.

New cards
22

are for holding small samples or for covering beakers or evaporating dishes.

New cards
37

Wire Gauze

on a ring supports beakers to be heated by Bunsen burners

New cards
38

thermometer

is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air

New cards
39

alcohol lamp

is used for heating, sterilization, and combustion in a laboratory.

New cards
40

microscope

is an instrument that can be used to observe small objects, even cells.

New cards
41

Work

is the product of the force applied and the displacement; it is based also if the object is moving on the direction of the force applied.

New cards
42

W=(F)(m)

What is the formula to find work? (Use parentheses "(a)" for multiplication, And the slash sign "/" for division)

New cards
43

J

What is the unit for work?( letter only)

New cards
44

No work done

If there is no force applied, there will be no movement and direction of the movement, therefore there is?

New cards
45

No work done

If there is a force applied but the object did not move, there will be no direction of the movement, therefore, there is still?

New cards
46

No work Done

If there is a force applied, and the object moved, but the direction of the movement is not the same as the direction of the force applied, there is still?

New cards
