Forces and Motion
These are a set of card I use to study for my science final.
an increase in speed
the fluid friction experienced by objects falling through the air
Total distance divided by total time
equal forces acting on an object in opposite directions
the change in position of an object
force into or from an action or state.
the resistance encountered when one object is moved in contact with another
the speed of an object at one instant of time
the combination of all forces acting on an object
friction that occurs when one surface slides over another
distance travelled per unit time
the friction that acts on objects that are not moving
Forces that produce a nonzero net force, which changes an object's motion
a variable quantity that can be resolved into components
speed in a given direction
acceleration toward the center of a curved or circular path
the inward force on a body moving in a curved path around another body
First Law of Motion
An object in motion will stay in motion unless it is acted upon by an outside force.
The force of attraction between all masses in the universe.
the tendency of an object to resist any change in its motion
Law of Conservation of Momentum
the rule that the total momentum of objects in an interaction does not change
an impelling force or strength
Second Law of Motion
the rate of change of momentum is proportional to the imposed force and goes in the direction of the force
Third Law of Motion
action and reaction.
a system of units used to express how heavy something is.
