experiment 2: newton's laws of motion Flashcards
it is a branch of mechanics that study the relationship of motion to the forces that causes it
dynamics
when did Sir Isaac Newton published the cause of motion
in 1687 in his mathematical principles of natural philosophy
what are the 3 statements of Newton’s laws of motion
law of inertia
law of acceleration
law of interaction
breifly explain the Newton’s laws of motion
law of inertia:
law of acceleration:
law of interaction:
law of inertia: net force on body is zero = no change in motion
law of acceleration: force to acceleration when motion is not zero
law of interaction: r/s btwn 2 interaction bodies on e/o
when all the forces that act upon an object are balanced, then the object is said to be in a state of equilibrium and has zero acceleration
first law of motion
what are 2 conditions of equilibrium must be satisfies to ensure that an object remains in static equilibrium
net force acting upon the object must be zero
net torque acting upon the object must also be zero
when an object is accelerating, it is not in equilibrium. the forces on it r not balanced so the net force is zero
second law of motion
the second law states that the acceleration of an object is dependent on 2 variables. what r they
net force acting upon the object
mass of the object
Tension
m g sin(-)
Convert kg to g
Kg times 1000 g
G divide 1000 kg p
F1
F2
T1/ T2
F1 ( grams times 980dyn)
F2(N times 100,000dyn)
T1/ T2 = r f cos (-)
Which torque is theoretical
T1
In law of acceleration, to find
a experimental
a theoretical
a experimental = 2x/ t^2
a theoretical = (mhanging/ mtotal IN GRAMS) x 980
For experiment 3, use what units for mass
Kg
Hence convert to kg, divide 1000
