Motion & Forces, 30 (25) - Coggle Diagram
Motion & Forces
Forces
Force and mass determine acceleration.
Force Equals Mass Times Acceleration
f = ma
f = force
m = mass
a = acceleration
Forces transfer momentum.
Objects in motion have momentum
p = mv
p = momentum
m = mass
v = velocity
Motion
Speed measures how fast position changes.
Calculating Speed
s = d/t
d = distance
t = time
s = speed
Acceleration measures how fast velocity changes
Calculating Acceleration
a = (vfinal - vinitial)/t
a = acceleration
vfinal = final velocity
vinitial = initial velocity
t = time
Work and Energy
Work is the use of force to move an object.
Calculating Work
w = fd
w = work
f = force
d = distance
Energy is transferred when work is done
Calculating Gravitational Potential Energy
gpe = mgh
gpe = gravitational potential energy
m = mass
g = acceleration due to earth's gravity
h = height
Calculating Kinetic Energy
KE = 0.5mv^2
KE = kinetic energy
v = velocity
m = mass
Gravity, Friction, and Pressure
Pressure depends on force and area
Pressure describes how a force is spread over an area.
p = f/a
p = pressure
f = force
a = area
