definitions
what is physics
the study of physical things
what is a formula
an equation to figure out an answer to something
who is Isaac Newton
an early physicist who developed the laws of motion
what is the first law
Objects in motion stay in motion and objects at rest stay at rest
what is net force
the final added up force
what is acceleration
speeding up
what is the formula for force
force = mass x acceleration
who is Galileo Galilei
an early physicist who came up with the law of falling bodies
what is the second law
the acceleration of an object depends on the forces acting on it (f=ma)
what is a force
a push or a pull
what is velocity
speeding up in a specific direction
what is the formula for speed
s=d/t
what is the difference between speed and velocity
velocity is also direction
what is the third law
for every action there is an equal and opposite reaction
what is friction
what happens when objects rub against each other usually slowing them down
what is a scalar velocity
something with magnitude
what is the formula for time
t=dxt
what is the main unit to measure speed we use
2
m/s
what is the name of the first law
the law of inertia
what is potential energy
energy that could become movement
what is a vector quantity
something with magnitude and direction oh yeah!
what is the formula for distace
d=sxt
name the 5 ways an object can accelerate
1.start moving 2.move faster 3.stop moving 4.move slower 5.change directions
what is the third law called
the law of action and reaction
what is the unit used to measure forces
newtons
