Newton's Laws
Every force has an equal, opposite force is Newton's ____ law.
Third
What do you call the range of influence of a non-contact force?
A field
The measure of a mass in motion
Momentum
All momentum and energy are transferred in this type of collision
Elastic
100% Potential energy/all potential energy/ or some variation of that answer
True or False: Acceleration is only when an object speeds up
False: It is also when it slows down or changes direction
Gravitational force increases or decreases when the objects get farther apart?
Where do you have the most kinetic energy on a rollercoaster?
At the bottom of the tallest hill/Lowest point in the rollercoaster
What happens to objects in an inelastic collsion?
They stick together
thermal energy transferred from one object to another
Heat
What is an object's resistance to a change in motion called?
Inertia
True or False: If you cut a magnet in half, one half will be a north pole and the other would be south.
False: Both halves would have a north and south pole
Gravitational Potential Energy increases or decreases when two objects get farther apart?
Increases
What method of heat transfer requires direct contact
Conduction

What is the amount of force over a period of time?
Lower density
What type of energy transformation takes place when you turn on a computer
Electrical Energy transformed into light and sound energy
What is the Net force of the scenario below?
10N 15N

Name 3 ways you can increase the strength of an electromagnet.
2. Increase the number of coils/turns in the wire
3. Use a ferromagnetic core (Such as iron or other metals that are magnetic)
KE would quadruple
Describe the difference between temperature and thermal energy
Temperature is the average amount of kinetic energy in a substance, thermal energy is the total amount of kinetic energy
