What's Newton's first law of motion?
Objects moving at a Constant velocity keeps moving unless an unbalanced net force acts on it
A Combination of forces Acting on an object.
The tendency of an object to resist a change in motion
Push or pull on an object
Equal but opposite forces acting on an object
The acceleration of an object that is slowing down
The acceleration of an object that is Speeding up
The rate of Change in velocity
A visual display of Information or data
A measure of speed Of an object and the direction it is traveling
The distance an object travels in an amount Of time
the speed of an object at one point in time
A measure of how far an object has moved
the distance and direction that something moved from a starting point
the total distance traveled in a unit of time

speed = -----------------------
What is the formula to calsulate average speed?
The formulas is:
average speed= -------------- total time
The fomula for acceleration
change in velocity
acceleration = ------------------
What is the formula to calculate change in velocity?
The formula is:
in = final - initial
velocity velocity velocity
What are the SI base units of measure?
An exact quanity that people agree to use to compare mesurements

Thy study of energy and matter that is scientific in nature
The study of living things
What are the three main categories of science?
The application of science to help people
A statement about what happens in nature that seems true all the time
Anything that represents an idea, event or object to improve understanding
What is expected cjanges how results are viewed
An explanation for a question or problem based on what you know and observe.
the measrement of the quantity of matter in a object
The mass per unit volume of material
An investigation that tests a hypothesis by collecting information under controlled conditions
What are the stpes of the scientific method?
State the problem
Hypothesis or Hypothesis
The steps a scientist follows when preforming an investigation
A standard in an experiment against which results are compared
A condition in an experiment that dose not change
In an experiment, the condition that is tested
The condition in an experiment that results from the changes made to the independent variable
A quantity that can have more that one value
The latin word for knowledge
List the three way velocity can change.
change in direction
change in speed
change in motion
What is Newton's second law of motion?
The net force acting on an object causes the object to accelerate in the direction of the net force.
The highest speed a falling objest can reach
A force that opposes the slliding motion of two srufaces that a are touching each other
A force that opposes the movement of objects through air
the force that opposes the motion of two surfaces sliding past each other
the force that keeps two surfaces at rest from sliding over each other
What is the formula to find acceleration when force and mass are known?
acceleration = --------------
What is the fromula to find force when mass in know?
net force = mass x acceleration
An attractive force between two objects
What is the law of Universal Gravitation?
Allow us to find the force of gravity beween any two objects if their masses ans the distance beween them are known.
The gravitational force exerted on an object
Acceleration toward the center of a curved path.
The net force exerted toward the center of a curved path
What is Newton's third law of motion?
To every action force ther is an equal and opposite reaction force.
the product of a moving object's mass and velocity
What is the fromula for momentum?
momentum = mass x velocity
