Distance
Displacemet
Displacemet
the length of the path between two points
Distance
forces on a object that combine to give a zero net force and do not change the motion of the object
balanced force
Change in a position in a certain amount of time
Motion
Positive speed increases and negative speed decreases.
What is the difference between positive and negative acceleration?
The quantity of motion of a moving body, measured as a product of its mass and velocity.
Momentum
what is a quantity that has magnitude and direction
Vector
divide the distance the object travels by the amount of time it takes to travel that distance (S=D/T)
speed
Vertical
y-axis
Meters per second squared or distance over time squared.
Two ways the unit for acceleration can be written.
A force acting briefly on a body and producing a finite change of momentum.
Impulse
How are displacements combined?
Add displacements using vector addition.
for every action there is an equal but opposite reaction
Newton's Third Law of Motion
Y axis, the outcome factor; the variable that may change in response to manipulations of the independent variable.
Dependent variable
The tendency of an object to resist any change in its motion.
What is inertia?
To be hit with force while in motion
Collide
What is a frame of reference? How is it used to measure motion?
To describe motion accurately and completely, a frame of reference is necessary.
the force on an object is equal to the mass of the object multiplied by the object's acceleration (F=MA)
Newton's Second Law of Motion
A place or object used for comparison to determine if an object is in motion. (ex. starting line)
Reference point
Mass
What property of matter is inertia related to?
An instance of one moving object or person striking violently against another.
Collision
movement in relation to a frame of reference. For example, as the train moves past a platform, people standing on the platform will see those on the train speeding by. But when the people on the train look at one another, they don't seem to be moving at all.
Relative Motion
an object in motion will remain in motion unless acted upon by another force
Newton's First Law of Motion
rate at which velocity changes, the rate at which velocity changes over time; an object accelerates if its speed, direction, or both change
Acceleration
Speed and direction.
What causes change in velocity?
The total linear momentum of a closed system remains constant through time, regardless of other possible changes within the system.
Law of Conservation of Momentum
