The state in which no physical changes occur; A state of steadiness
A "stretching" force that is exerted on any elastic object that is stretched from an equilibrium state.
A push or a pull that causes a change in the state of motion.
To find the resultant of two non-parallel vectors, construct a parallelogram wherein the two vectors are adjacent sides. The diagonal of the parallelogram shows the resultant.
The upward force that balances the weight of an object on a surface
The combination of all the forces acting on an object. An object only moves when experiencing this.
The sum of two or more vectors.
An arrow that represents both the magnitude and direction of a quantity.
Whenever the net force on an object is zero, the object is said to be in mechanical equilibrium. Can be expressed as a mathematical equation:
∑ F = 0
The force due to Earth's gravitational pull on an object.
A quantity that requires both magnitude and direction for a complete and accurate description.
A quantity that can be described by magnitude only. It has no direction. Time, area, volume, and energy are all examples of this.
objects moving at a constant speed in a straight line path are said to be in this
is either straight up or straight down. all objects seek a natural resting place. large objects such as boulders moved towards the ground and light objects, like smoke moved to the sky
imposed motion. the result of forces that are pushed or pulled. ex-carts pulled by a horse, a tug-a-war match, these are violent motions
a push or a pull that causes a change in state of motion
the force that acts between materials that touch as the move past each other causes by the irregularities in the surface of objects in contact
the property of a body to resist change to its state of motion
Newton's First Law of Motion
every object continues in a state of rest, or of uniform speed in a straight line, unless acted on by a nonzero net force
the amount of matter in an object
measured in inertia
more the mass the greater inertia
the force due to gravity on Earth
Know the difference between mass and weight, and mass and volume
v=the amount space something takes up
measured in cubic cm, m, l, or mm
m=the amount of matter in an object
w=the force due to gravity on Earth
2 major accomplishments of Isaac Newton
-famous for creating inertia
-discovering white light is a combination of all colors (ROYGBIV)
-he derived three laws of motion from Galileo's view
2 major accomplishments of Galileo
-first person to use telescope to look at the night sky
-famous for discovering moons that orbit Jupitor
2 major accomplishments of Aristotle
-created two points of motion (natural motion and violent motion)
-concluded all heavily objects orbit Earth
the views of Copernicus and Ptolemy in regards to the motion of the heavenly bodies
-Ptolemy thought that everything orbited Earth and Jupiter Mars and Saturn had epicycles, he made them up to explain their phases in orbit
-Copernicus used the motion of Venus to conclude that heavenly bodies orbit the sun
What process did Galileo use to earn him the name of "Father of Modern Science?"
he preformed experimental procedures
Newton changed the way we view science by changing the perspective of laws from being in terms of the _____________ to in terms of the _________________
the earth, the universe
Identify the difference between static equilibrium and dynamic equilibrium
static: said to be objects at rest
dynamic: said to be objects that move at constant speed that move in a straight path
examples of vector quantities
force, velocity, acceleration, and momentum
a quantity that requires both magnitude and direction for a complete and accurate description
examples of scalar quantities
time, area, volume, and energy
a quantity that can be described by magnitude only. It has no direction.
Be able to draw the resultant of two vectors using the parallelogram rule
