CORRECT (VERIFIED SOLUTIONS)
Displacement .....ANSWER.....- it refers to the distance that a
object is from its starting point
Motion .....ANSWER.....- when an object is motion its displacement
is constantly changing
- it is describe by displacement, velocity, and acceleration
Speed .....ANSWER.....- refers to the distance traveled by an
object per unit of time.
velocity .....ANSWER.....- refers to speed in a given direction;
therefore it tells us two things about a moving object: its speed
and its direction
,Page 2 of 37
acceleration .....ANSWER.....- refers to to any change of velocity
either positive or negative.
deceleration .....ANSWER.....- refers to the negative acceleration
or a decrease in velocity and can cause a change in direction
momentum .....ANSWER.....- is equal to the mass of an object
multiplied by its velocity
- Momentum = (Mass)(Velocity)
conservation of momentum .....ANSWER.....- States that the total
momentum of an isolated system is always constant
-Ex: during a collision between two bodies, the momentum of
each body changes, but the total momentum is is conserved. One
object may lose momentum, but the momentum lost by the object
is gained by the other.
,Page 3 of 37
vector .....ANSWER.....- velocity and acceleration can both be
described using vectors because they both have magnitude and
direction.
Newton's First Law .....ANSWER.....- states that objects in motion
tend to stay in motion and that objects at rest tend to stay at rest
inertia .....ANSWER.....- is the property of matter that resist any
change in motion
Newton's second law .....ANSWER.....- describes the relationship
between force, mass,and acceleration.
- it states that force is applied on an object equals the mass of
the object times its acceleration
force .....ANSWER.....F= ma
newton .....ANSWER.....- (N) is the unit that represents a force that
accelerates a mass of 1 kilogram 1 meter per second
, Page 4 of 37
friction .....ANSWER.....- sliding box along a floor, giving it
velocity, it does not continue at that speed but stops. This is due
to friction between the box and floor
- whenever a force is exerted along a surface or whenever an
object has a velocity along the surface, and the two surfaces
touch, there is force called friction
gravity .....ANSWER.....- is the force of attraction between all
objects in the universe
weight .....ANSWER.....- the pull of gravity on an object
determines its weight
torque .....ANSWER.....- the ability of a force that is applied
perpendicularly to rotate an object around an axis, such as using
a wrench to turn a bolt is measured by the quantity torque
