Physics Test 1 Ch.'s 1-6 Flashcards
What does the length of the vector represent?
magnitude
Vector
something that has magnitude and direction
Scalar
something that only has magnitude
Acceleration due to gravity
a=9.8 m/s^2
V and a of object at its highest point that has been thrown up
Vy=o
a=-9.8 m/s^2
t up= t down if…
something that is thrown up and lands at the same hight from which it was thrown
a parallel to v
change in magnitude
a perpendicular to v
change in direction
ax, ay, and delta v for projectile motion
ax=0
ay=-9.8 m/s^2
delta v=0
relationship of initial velocity and final velocity in the x direction
they are equal to each other
how to find x component of a velocity vector
magnitude times cos of the angle
how to find y component of a velocity vector
magnitude times sin of the angle
Newton’s 1st law
an object at rest remains at rest, an object at a constant velocity in a constant direction remains that way, unless there’s an outside force(Fnet)
Equilibrium
if Fnet=0
Dynamic Equilibrium
Fnet=0 and V is constant but doesn’t equal 0
Static Equilibrium
Fnet=0 and V=0
What does Fnet= in non Equilibrium?
ma
How to convert radians to meters
Multiply the radians by the radius in meters
How to convert radians to meters
Multiply the radians by the radius in meters
Newtons 2nd Law
The relationship between force and acceleration is mass
Fnet=m*a
Law of inertia(part of newtons 1st law)
The property of an object that resists and change in motion
