Miscellaneous
100
Change of position over time.
What is motion?
100
States of energy.
What are potential and kinetic energy?
100
An object in motion stays in motion with the same velocity, or an object at rest remains at rest, until acted upon by an unbalanced outside force.
What is Newton's 1st law (law of inertia)?
100
Varies with gravity; actually considered a force and should be measured in Newtons, but it is commonly measure with another unit.
What is weight?
200

The length between two objects or the length an object has travelled

What is distance

200

What is the unit SI unit for energy

What is a Joule?

200
A basketball just before release has equal and opposite forces acting upon it.
What is Newton's 3rd law (law of action/reaction forces)?
200
Type of fluid friction that acts upon airplanes.
What is air resistance?
300
These can cause a change in velocity.
What is speed and/or direction?
300

What is the energy of movement?

What is kinetic energy ?

300
At-a-distance, "unseen" force of attraction Newton discovered by applying his knowledge of his 1st law.
What is gravity?
300
Magnets have these characteristics and act differently when arranged when likes or opposites are combined.
What are (north & south) poles?
400
A downward-sloping line on a velocity-time graph.
What is negative acceleration or deceleration?
400
Energy can neither be created or destroyed; it can only be transformed.
What is the law of conservation of energy?
400

Which law includes F=MA

Newtons 2nd law

400
Electricity pushes electrons through wires, creating a magnetic field around iron.
What is electromagnetism?
500
A horizontal line on a distance-time graph.
What is at rest or speed=0?
500
Increases with speed.
What is kinetic energy?
500
Example of Newton's 2nd law.
(answers vary - must explain how f=ma; more force-greater acceleration)
500

A horse ran 500 meters down the hill in 50 seconds.  What is the velocity of the horse?

10m/s
