Balanced and Unbalanced Forces
____________ Forces are forces on an object that ______________ the motion. The net force is
_____.
___________ Forces are forces on an object that ____________ in the motion of the object. One
side tends to _____________ the other. One side has the _____________.
Different types of forces: ______________________________
Forces cause _____________. Acceleration is
_____________________________________________. We don't use the word ______________
for slowing down.
Forces are measured in units called _________. A ________________ is the measurement tool used
to determine net force.
Machines: Inclined Planes and Pulleys
A machine is a device that ________________________________. It can change:
 the amount of force you exert, the _______________________;
 the distance over which you exert the force, the _________________________; and
 the _______________________ in which you exert the force.
An inclined plane is a ________________________ that is __________________ at a particular
angle.
A pulley can make work easier in two ways:
 by ________________________ the amount of _________________ force needed; and
 by changing the __________________________ of the input force.
Kinetic and Potential Energy
Energy is the ability to do ___________ or _______________. Energy comes in two basic types:
______________________________________
Kinetic energy is the energy an object has because of its _______________. It depends on the
object's ____________ and velocity. Kinetic energy is ____________________________.
Potential energy is the energy that results from the ______________ or __________ of an object.
Potential energy is energy that is ___________________ in a system.
How are Potential and Kinetic Energy related?
When an object _______________, potential energy ______________ into kinetic energy. An object
at rest has ____________________ energy but not ________________ energy.
Calculate Average Speed
Speed is a type of _____________. A rate is a measurement of something that ___________ or
______________ in one ____________ of time.
The speed of an object is the distance the object travels per unit of time.
Speed = ____________________________________________
