Newton's Laws of Motion
Newton’s first law of motion states that an object in motion remains in motion and an object at rest remains at rest unless acted upon by unbalanced force. This can also be called:
What is the law of inertia?
_______ is the change of an objects position.
What is Motion?
This is the transfer of heat from warmer object to a cooler object through direct contact.
What is Conduction?
Example: touching a hot stove with your hand.
Name the formula to calculate average speed.
What is
Speed = Distance/Time?
This unit is used to measure work.
What is a joule?
Wearing a seat belt protects you from effects that are best explained by understanding
What is the law of inertia?
Acceleration can occur in three different ways, what are they?
What is:
Speed Up (Accelerate)
Slow Down (Decelerate)
Change Directions?
This is the transfer of heat through electromagnetic rays.
Examples: Microwave, sun heating earth or warmth you feel when you sit next to a fire.

What is Speed?
This is the decrease in effort that is needed to move an object called.
What is Mechanical Advantage?

What is Momentum?
What is Convection?
Examples: Air in your home.

A fixed unmoving object or location is ______.
What is a reference point?
Thermal Energy always moves from _______ to _______ energy.
What is high to low.
Sally was at the front of the race when suddenly she stumbled over a piece of gravel. Her average speed decreased.
What is Acceleration? (deceleration)
This simple machine consists of two inclined planes placed back to back.
What is a wedge?
It took one student to pick up a box filled with feathers and two students to pick up the same sized box filled with books.
What is Newton's Second Law of Motion?
Force = Mass x Acceleration
______ is the ability to make something move.
What is Mechanical Energy?
BONUS!!! (Answer this question for a bonus prize)
What's the difference between temperature and thermal energy.
Temperature is the average kinetic energy of molecules in a substance, and thermal energy is the sum of KINETIC and POTENTIAL energies of all the molecules in a substance.

What is 3 miles/minute?
This simple machine makes work easier by either changing the direction of the force or by reducing the amount of force needed to move an object.
