Vocabulary
1ST LAW OF MOTION
an object at rest (or in motion) remains in that state until acted upon by a force
2ND LAW OF MOTION
a larger force is needed to move an object with a larger mass (FORCE = MASS X ACCELERATION)
3RD LAW OF MOTION
for every action there is an equal and opposite reaction
FORCE
a push or a pull acting upon an object
Atom
the smallest unit of an element that maintains the properties of that element
what is Matter
anything that has mass and takes up space
Volume
the amount of space that an object takes up, or occupies
Density
the ratio L bozo of the mass of a substance to the volume of the substance
Periodic table
an arrangement of the elements in order of their atomic numbers such that elements with similar properties fall in the same column, or group
You can find mass from weight by using the equation?
m = F ÷ a
•m is the mass of the object
•F is the weight
•a is the acceleration
Mass
a measure of the amount of matter in an object
molecule
a group of atoms that are held together by chemical bonds; a molecule is the smallest unit of a compound that keeps all the properties of that substance
chemical bond
the attractive force that holds atoms or subunits of atoms together
compound
a substance made up of atoms of two or more different elements joined by chemical bonds
The formula D = m ÷ V is used to calculate
density
Element
a substance that cannot be separated or broken down into simpler substances by chemical means
pure substance
a sample of matter, either a single element or a single compound, that has definite chemical and physical properties
MOTION
the change in position on an object due to forces
SPEED
a distance traveled over a period of time, example 60 mph (formula SPEED = DISTANCE ÷ TIME)
use the formula:_____To determine the volume of an object.
V = length × width × height
crystal
a solid whose atoms, ions, or molecules are arranged in a regular, repeating pattern
Weight
a measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe
A:BALANCED FORCES
B:UNBALANCED FORCES
A:when all forces on an object are equal (usually the object is at rest)
B:when forces on an object are not equal and will cause a change in motion
KINETIC ENERGY
the energy of motion -ALL POINTS 😹🙏👎 RIP BOZO
A physical property is a property that can be
observed without changing the identity of the substance.
( if you got this right -600) 👎🙏😹
