Momentum
& Collision
Vector quantity that determines
the object's potential in collision or explosion.
p = mv
F = △p/△t
Momentum
Elastic collision/explosion:
The collision/explosion that preserves both energy and momentum.
Inelastic collision/explosion
The collision/explosion that preserves only momentum.
Circular Motion
An object moving on a plane in
circle.
Centripetal acceleration = v^2/r
Centripetal force = F = mv^2/r
Frequency = 1/t
Work & Power
& Energy
Work:
Scalar quantity that tells how efficient a force is in order to move an object.
Power:
How work is done in a period
of time.
P = W/△t
Energy:
Scalar quantity that shows
the ability to work.
Kinetic Energy
(Moving object)
E(k) = 1/2mv^2
W = △Ek (Work - Kinetic Energy)
Potential Energy
(Object at rest)
Gravitational potential energy =
mgh
Elastic potential energy =
1/2kx^2
Law of conservation of energy:
⃤ (E(x) + E(p) = 0
W = ma△x
W = 1/2mv^2 - 1/2mu^2
W = F△x (Same direction)
W = F△x cos 0 (Angle theta)
Equilibrium
State of an object where there is no total force acting on the object.
Translational Equilibrium
F = 0
N - W = 0,
N = W
Rotational Equilibrium
State of object that doesn't rotate or rotate with constant angular speed.
If net force is zero, the movement of object stays the same.
