speed and direction of an object
velocity
inertia
energy is the ability to do _________ or cause _______
work and change
how fast an object is moving
acceleration
a force that draws an object toward the center of the earth
gravity
the energy stored in an object
potential energy
when an object is not moving at all it is at ______
rest
a unit of force
newton
For every action there is an equal and opposite reaction
Newton's Third Law
energy of a moving object
kinetic
a push or pull on an object
force
give an example for force (either a push or a pull)
answers will vary
an object at rest will stay at rest and an object in motion with remain in motion until acted upon by an outside force
Newton's First Law
kinetic energy is dependent on _________ and _______
speed and mass
when two objects rub together creating an object to slow down
friction
give an example of movement
answers will vary
the greater the mass of an object being accelerated, the greater amount of force needed to accelerate it
Newton's Second Law
potential energy is dependent on these two things
position and mass `
