Torque Notes and Practice Set
Notes:
Torque, moment or moment of force is the tendency of a force to rotate an
object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a
torque c

Centripetal Acceleration
Notes:
Consider an object moving in a circle of radius r with constant angular
velocity. The tangential speed is constant, but t
Heat of Phase Change Notes and Practice Set
NOTES:
Transitions between solid, liquid, and gaseous phases typically involve
large amounts of energy compared to the specific heat.
If heat were added a
Overcoming Friction Notes and Practice Set
NOTES:
Friction is the force resisting the relative motion of solid surfaces, fluid
layers, and material elements sliding against each other. There are sever
Average Acceleration Notes and Practice Set
NOTES:
Acceleration = a change in speed: (Speeding upSlowing down or
changing direction)
Average acceleration is the rate at which velocity changes.

Average Velocity and Displacement Notes and
Practice Set
NOTES:
Velocity is a vector physical quantity; both magnitude and direction are
required to define it.
o Velocity is a vector quantity that re
Stopping Distance Notes and Practice Set
NOTES:
Momentum
o A quantity that describes an object's resistance to stopping (a kind of
"moving inertia").
o Represented by the symbol p (boldface).
o The p
Force and Impulse Notes and Practice Set
NOTES:
In classical mechanics, impulse is defined as the integral of a force with
respect to time, which gives you the change in the momentum of the body
being
Momentum Practice Set
NOTES:
In classical mechanics, linear momentum or translational momentum is the
product of the mass and velocity of an object.
o For example, a heavy truck moving fast has a larg
