SI Units/Metric System
The SI units for length, time, and mass
What are the meter, the second, and the kilogram?
The symbols for position, displacement, and distance
What are d , ∆d , and ∆d?
Continue the sentence:
Newton's first law of motion states that an object at rest will remain at rest . . .
What is "unless acted upon by an unbalanced force"?
Kinetic energy is conserved in this type of collision
What is an elastic collision?
Fill in the blank:
Regardless of whether speed changes, an object traveling in a circular path is accelerating because ___
What is the object is constantly changing direction?
SI is an abbreviation for this name
What is Système international?
The major difference between displacement and distance
What is "displacement is the net change in position, whereas distance is the total length of travel"?
This property can be compared to a "cosmic stubbornness" and is the tendency of an object to resist change in its state of motion
What is inertia?
Mechanical energy is the sum of these two types of energy
What are bulk kinetic energy and gravitational potential energy?
The definition for the centripetal force
What is the net force acting on an object directed towards the center?
The metric prefix for a value of 106
What is mega?
The restriction of the following kinematics equation:
v12-v02=2a∆d
What is motion can only be in one direction?
The normal force of an object acts in this direction
What is perpendicular to the object's surface?
This factor is irrelevant to calculations in a conservative system
What is mass?
What is the direction tangent to the circle at that point?
The metric prefix for a value of 10-12
What is pica?
Fill in the blank:
Acceleration can be a ___ quantity (vector and/or scalar)
What is acceleration can be a vector or scalar quantity (depending on the given information)?
Fill in the blanks:
When a net force acts on an object, the object accelerates with an acceleration directly proportional to ___ and inversely proportional to ___
What are that net force and the object's mass?
In this type of collision two objects start attached and then separate during the collision
What is a ballistic collision?
The angular kinematics equations rest on this assumption
What is constant angular acceleration?
The metric prefix for a value of 1015
What is peta?
Position must be given in respect to this
What is a stated point of reference?
Newton's 3rd law states that when two objects interact, they apply forces of equal magnitude and opposite direction to one another, and this is the reason why those forces do not cancel each other out
What is they are acting on different objects?
The law of conservation of momentum relies on this assumption
What is the objects collide on a horizontal frictionless surface?
The arc on the circumference of a circle can be approximated to this for a small enough angular displacement
What is a straight line?
