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

a push or pull

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.

10N←O→58N =

48N

32←O←41

73N

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

terminal velocity
