Physics Regular- Perella Period 5

###
inertia

the resistance of change in an object

###
inertia is related to

the amount of mass in an object

###
the more mass you have the more

inertia you have

###
force can change an object's

acceleration, decceleration, direction

###
net force

the sum of all the forces acting on an object

###
when an object is in constant motion the net force is

0

###
and object with more mass/inertia needs more _____ to change its acceleration, decceleration, or direction.

force

###
the amount of force in an object is directly proportional to its

acceleration

###
newton second law relates

the net force, mass, and acceleration of an object

###
free fall

when gravity is the only force acting on an object

###
an object with more surface area has more

air resistance

###
air resistance

a force acting against gravity causing an object to deccelerate

###
terminal velocity

when the net force of an object is 0 and the object is in constant speed

###
acceleration due to gravity is

9.8 m/s/s

###
force due to gravity is an object's

weight

###
the find the speed of a distance vs. time graph you must determine the

slope

###
to find the acceleration of a speed vs. time graph you must determine

the slope

###
to find the distance in a speed vs. time graph you must determine

the area under line

###
the find the mass in a force vs. acceleration graph one must determine the

slope.

###
↑⁻⁻↓⁻⁻↑⁻⁻↓ air resistance and gravity are equal, the object is at

terminal velocity
