Science "force" Flashcards
___ is a push or pull on a object with mass causes it to change its velocity
Force
____ is a action or process of moving or being move
Motion
____ is a change in position of an object, and its a gap between initial and final position
Displacement
____ is the speed at which sometimes moves in a particular direction
Velocity
____ a change in velocity with time, in terms of both speed and direction
Acceleration
distance or quantity
Magnitude
______ is a location of something relative to something else (North, South, East, West)
Direction
______ or objects moving in straight line at constant speed
Uniform Motion
______ where the object covers unequal displacement at equal interval’s of time. (unequal displacement in equal interval time)
Non-uniform motion
the location of where the force is applied
point of application
the straight line passing through the point of application and is parallel to the direction of force
line of action
where objects touch or contact with each other
contact forces
a force given to a person or object by another person or object
applied
the force acting against or opposite an object in contact with which makes the movement of the object slow down. ____ always opposes the motion of an object
friction
is the force that acts perpendicular to the surface of the object in contact with
normal
is the force applied to string, rope, chain, or cable
Tension
forces where objects do not touch or contact with each other
non-contact forces
bigat
mass
is the force of attraction between two objects. in the case of the earth, this ____ cause objects to fall down to the ground
gravitational
are forces exerted on a field of attraction or repulsion as in the case of magnets and other magnetic materials
magnetic
forces that are equal in magnitude but opposite in direction are called _________
balanced Force
forces that cause a change in the motion of an object are _________
unbalanced forces
is the sum of all forces acting on an object
net or resultant force
friction is a force that acts between surfaces that are in contact with one another
friction force
