Vocab
The tendency to resist changes in motion.
What is inertia.
a physical quantity, represented by a scalar, vector, or tensor, that has a value for each point in space and time.
field
The universal force of attraction acting between all bodies of matter. It is by far the weakest known force in nature.
Gravity
Force that resists the sliding or rolling of one solid object over another.
Friction
Change with time of the position or orientation of a body.
Motion
Distance and direction of an object's change in position from the starting point.
Displacement
The rate of change of velocity
acceleration
Force that opposes the motion of objects that move through the air
air resistance
Distance an objects travels per unit of time
Speed
Gravitational force exerted on or among objects
Weight
F=ma
Newton's Second Law of Motion
Acceleration of an object toward the center of a curved or circular path
Centripetal acceleration
a force directed towards the center of a curved or circular path
Centripetal force
product of the mass of a particle and its velocity.
Momentum
a push or pull
Force
an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by an external force.
Newton's first law of motion
state of a body that moves freely in any manner in the presence of gravity.
free fall
in a closed system (where no external forces act), the total momentum of all objects in the system remains constant, even if they interact with each other.
Law of conservation of momentum
law of action and reaction, states that for every action (force) there is an equal and opposite reaction.
Newton's Third law of Motion
the constant speed a falling object eventually reaches when the force of air resistance (drag) equals the force of gravity, resulting in zero net force and no further acceleration.
terminal velocity
speed in combination with the direction of motion of an object.
Velocity
the vector sum of all the forces that act upon an object.
Net force
