motion – the state in which one object’s distance from another is changing.
reference point – a place or object used for comparison to determine if an object is in motion.
position – the exact location of an object.
International System of Units (SI) - a system of measurement based on multiples of 10 and on
established measures of mass, length and time.
Meter – the SI unit length
Speed – the distance an object travels per unit of time
Average speed – the overall rate of speed at which an object moves; calculated by dividing the
total distance an object travels by the total time
Instantaneous Speed – the speed of an object at one instant of time
Vertical Axis – “Y-Axis” A line that runs up and own along the side of a graph, on which the
responding variable (dependent variable) is labeled
Horizontal Axis – (“X-Axis”) A line that runs left to right along the bottom of a graph, on which
the manipulated variable ( independent variable) is labeled.
Slope – the steepness of a line on a graph, equal to its vertical change divided by its horizontal
change.
Origin – the point where the x-axis and y-axis cross on a graph
Coordinate – A pair of numbers used to determine the position of a point on a graph
Data point – A point on a graph showing the location of a piece of data
Acceleration – the rate at which velocity changes. Increasing speed, decreasing speed or
changing direction. Formula: Acceleration = Final Speed – Initial Speed/Time
Force – a push or pull exerted on an object
Newton – a unit of measure that equals the force required to accelerate 1 kilogram of mass at 1
meter per second per second.
Net force – the overall force on an object when all the individual forces acting on it are added
together.
Unbalanced forces – forces that produce a nonzero net force, which changes an object’s motion.
Balanced forces – equal forces acting on an object in opposite directions which does NOT
change an object’s motion.
Friction – the force that one surface exerts on another when the two surfaces rub against one
another
Static Friction – friction that acts on objects that are not moving
Sliding Friction – friction that occurs when one solid surface slides over another
Rolling Friction - friction that occurs when an object rolls over a surface
Fluid Friction – friction that occurs as an object moves through a fluid
Gravity- the force that pulls objects toward each other
Mass – the amount of matter in an object
Weight – the force of gravity on an object at the surface of a planet
Air resistance – the fluid friction experienced by objects falling through the air
Buoyant force – the upward force exerted by a fluid on a submerged object.
Newton’s First Law of Motion – an object at rest will remain at rest, and an object moving at a
constant velocity will continue moving at a constant velocity, unless acted upon by an unbalanced
force.
Inertia – the tendency of an object to resist any change in its motion
Newton’s Second Law of Motion- acceleration depends on the object’s mass and on the net
force acting on the object.
34. Newton’s Third Law of Motion- if one object exerts a force on another object, then the second
object exerts a force of equal strength in the opposite direction on the first object.
35. Momentum – the product of an object’s mass and velocity
36. Law of Conservation of Momentum – the rule that in the absence of outside forces the total
momentum oh objects that interact does not change
37. Work – force exerted on an object that causes it to move
38. Power – the rate at which work is done
39. Machine – a device that changes the amount of force exerted, the distance over which a force is
exerted.
40. input force – the force exerted on a machine
41. output work – the force exerted on an object by a machine
42. mechanical advantage – the number of times a machine increases a force exerted on it
43. efficiency – the percentage of the input work that is concerted to output work
44. potential energy – stored energy
45. kinetic energy – energy that is in motion
