Unit 2 Flashcards
What is the equation for the force of Gravity
Mass * Gravitational Energy (9.8 N)
What is Newtons First Law and what does it mean?
Objects in motion will stay in motion unless acted upon by unbalanced forces
If all forces are balanced there is a constant velocity
What is the kinematics equation for when there is no accelration given?
x=1/2(Vf+Vo)t
What is the formula to find the force on the
x axis
F * (Cos theta )
What is the force equal to on the y axis
F * (sin theta)
How do you find the sum of all forces (on x or y)
Sum of all forces = mass * acceleration
What is the equation to find the acceleration of a pulley system with two mass objects
A= (m2-m1)g / (m1+m2)
How do I know which force to subtract in system equations of physics
The first force to subtract is the numerical value of the force that is inflicted the objects movement
What is Newton’s second law
The acceleration of an object is directly proportional to the net force of an object and inversely proportional to the mass
What is meters third law
For every action there is an equal and opposite reaction
How do I find the time vertically traveled with no velocity given
d=1/2at^2
How do I find the distance when it is a constant velocity given
distance = velocity*time
