◉ Displacement.
Answer: Distance and direction of an object's change in position
from the starting point.
◉ position.
Answer: the location of an object
◉ Speed.
Answer: The distance an object travels per unit of time
◉ Acceleration.
Answer: The rate at which velocity changes
◉ instantaneous speed.
Answer: the speed of an object at one instant of time
◉ Force.
,Answer: A push or pull on a object
◉ net force.
Answer: The combination of all forces acting on an object
◉ constant speed.
Answer: Speed that does not change
◉ instantaneous speed.
Answer: the speed of an object at one instant of time
◉ average speed.
Answer: total distance divided by total time
◉ Newton's first law ( Aka Law of Inertia).
Answer: "An object at rest remains at rest, and an object in motion
will remain in motion unless acted upon by some external net force."
A rock for example will remain at rest, it won't start spontaneously
moving. An object in motion, that does not encounter any friction
will keep moving, like an object floating in space.
, ◉ Newton's Second Law.
Answer: Force = mass x acceleration ( F=ma)
To find acceleration: A= F/ m
" the acceleration an object experiences is directly proportional to
the applied force and inversely ( in the opposite manner)
proportional to its mass.
◉ Newton's Third Law.
Answer: For every action there is an equal and opposite reaction.
As a car hits a wall, it's force is applied to the wall but the force of the
wall also acts on the car.
Remember, there can never be a single isolated force, forces always
come in pairs.
◉ coefficient of friction.
Answer: the ratio of the force of friction to the normal force acting
between two objects. When you find a coefficient of friction, you're
calculating the resistance to motion at the interface of two surfaces
of similar or dissimilar materials.
